Fabio, i fkin love you dude! This is absolutely insane! 5800x + 7900XTX user here, playing 4k resolution. The only game where i had huge problems with stuttering was Farming Simulator 2022, in Silverrun Forrest Map especially where there were lots and lots of trees. Couldn't get past 60 fps no matter what, with drops to 30 happening a lot, CPU hovering at 20% use, GPU usage never going over 60%, it was unplayable and i couldn't understand why since FS22 is a shitty game, poorly optimized indeed but still... So I disabled core isolation and the FPS on that map jumped to 120. Double than before! And it's a joy to play now. I can't believe it! You made my day sir and you made me love my AMD setup again. Thank you Fabio!
Exactly. I disabled mine too to have my computer working as it should. All other youtubers pretend that core isolation does not affect gaming but they are wrong

What a legend! Can confirm turning off memory integrity checking gave me at least a 6-7% increase in max fps potential on a heavily modded cyberpunk on my 7800x3d/4090 combo, but the real winner here is not the max/avg fps, it's the 1% lows and stutter reduction. Capping my fps to 60 used to still give me stutters in specific areas and scenarios, those are almost completely gone and my frame time graph is a thing of beauty now!

Windows 11 required TPM and virtualization and it was tanking performance in games. They also had issues with Ryzen. If you compare them both now on a modern machine you will not notice any difference however. This is especially true because windows 11 simply cannot be installed on old machines.
@@SirSomnolent the problem is most of the PC gamer are on Nvidia and it performs worse without windows because it has not been very open source. I saw news implying they were working with Linux recently however so this may be resolved now or in the near future.
Just did this in WoW with my R9 7900. Never thought this would have any impact but I was wrong. A solid 15 - 20 FPS + in Valdrakken where it's heavily CPU bound cause of player density. Nice one, TY
I noticed this fairly quickly after benching my new PC a few weeks back and noticing my setup got less score than identical setups. I disabled core isolation and immediately received the "Free PC Upgrade" achievement in 3dmark, my bench score jumping by ~15% e.g. in TimeSpy from 27k to 31k! Insane.
I saw the thumbnail and was like "how tf did this bs reach me? How did I sub to those channels". I immediately turned interested af after I've read the name of the channel lol, we all agree those "+20/30/40 FPS" optimization guides are shit, but yours are never click bait, keep it up Fabio!
I keep my cores isolated in the secret dungeon underneath my flat. They know that they can only have supper if they properly evaluate their life choices.
I think it is worth noting that virtualization is disable by default in bios. And I am pretty sure most people don't use it, so they don't have to worry about this.
@AncientGameplays so you are saying that with newer boards, it is enabled by default? Damn, I had my fare share of boards in the past, and it was always disabled by default. But since microsft needs it for this crap, it is not a surprise that the settings changed. I saw a bios update for my b450 had something about important security changes in update notes, so maybe they are turning it on by default like they did tpm.
That's crazy. Usually most of these "change settings to boost fps" videos are a load of nothing. But the fact that you can increase a card's performance by 30% is game changing!
Disabled it on my FX8350 (i know its old ) and it brought me around ~ 20 FPS in Mechwarrior Online, never thought that this feature cost performance if it isnt used.
I just did this with my R5 2600 as well especially since I don't use BlueStacks anymore or anything like that. Hopefully I get at least 10-20 more fps which will be godsent with this old CPU!
you can also check if virtualization is on or off on task manager, go to performance tab and select the cpu stats... it shows on bottom right if virtualization is on
WOW! Thank you!!! Immediate difference noticed! EDIT: Just wanted to add that I saw the difference in the funniest things - like Mafia 2 running better, Quake 4 running better. Things like Doom 2016 already ran like butter on my system, but older games seemed to really draw differently from the gpu/cpu, very interesting!
If virtualization is shut off altogether like you did there's no need to worry about needing core isolation. It can always turned back on if or when its needed..
Did this about a month ago while playing Helldivers 2 was Heavily CPU Bound , Went from avg 60 FPS (~50-70 % GPU util) to avg 80 FPS (~80-95% GPU util) RTX 4070 + Ryzen 7 5800x Also tweaked RAM slightly

You know what would also help? If developers actually optimized their games. No, seriously. Computers get faster and faster and devs get lazier and lazier with bloat, thinking the extra memory and stuff will take care of it. Computers are the fastest they've ever been and what's the trending feature people want to use and have supported? Downscaling their game and playing at a lower resolution and masking it with AI upscaling. Computers are really powerful, we should be able to use native resolutions with little to no issues. The fact that expensive RTX supercomputers nowadays sometimes have to go as low as 720p (and again, masking it by upscale it) to get stable framerates is really saddening. That's probably why games are hundreds of GB, because of tons of HUGE, uncompressed textures and high-poly assets that are that way just for the sake of fidelity, even though you could get the exact same results with less. All the shaders, material and model features in game engines that we've had for the past decade or so are specifically-designed so that we don't HAVE to be so extreme with our detail. Like instead of modeling the individual pores of someone's face, using normal maps, smooth shading, and optimized lighting techniques to get the same thing so the computer doesn't have to work as hard. Or instead of dynamically raytracing the entire map, using baked pre-rendered lighting that has everything already calculated ahead of time. That sorta stuff. Forza Horizon 4 is a great example. It's super photorealistic, yet optimized SO well that my mid-range PC can max it with no issues at all. Lighting techniques, models and shaders are detailed yet do it in a way that doesn't melt your computer by using as many efficient techniques as possible and getting rid of any unnecessary bloat. Meanwhile some games today are equal in visual quality, or sometimes even worse, yet run like hot garbage because everything's so unnecessarily computational.
Virtualization based security has always hindered fps but it has gotten better. It used to be a lot worse. However, VBS has significantly improved the security of the OS. Hopefully, they will get it even closer with newer versions.
Core isolation is one of those security features that have been known for a long time to affect gaming, but I didn't realize that it was now on by default.

Yup discovered that this was the reason my 8700k sucked now. after disabling my fps went up 15% to 100% in some games. Bf1 for instance weny from 100 to the max that the engine allows which is i think 200.
For some of us, security is more important. Good to know not all games are affected by Core Isolation. This is actually a known issue for years. I guess some games have engineered in a way to minimise the performance impact.
@@AncientGameplays anyway for my main rig which I game & mine, it's off but every other devices it's on. Had to be extremely careful with downloads as I keep client data for work.
Man as soon as I heard that virtualization needed to be off I knew I was fucked since I often work with VMs, but if this actually works even by keeping virtualization on you are a hero
Thanks for another helpful video. I used to know every little setting when I worked in IT but not anymore so it's always fun to learn these things again. Checked in windows and it couldn't open the page and i assume that means it's off in the BIOS and i actually am still pretty good. lol
I missed a graph comparing synthetic benchmarks, like CineBench, for example. I'm going to try out your tip in a game I play a lot and which has a huge CPU bottleneck, which is Squad. Anyway, excellent video as always, Fábio!
Interesting find, I wonder how this setting may impact the performance of some VR games, like VRChat, since that one is especially heavy on the CPU in some worlds.
I have never heard of this setting, amazing work. All these big big tech channels with so many employees and no mention on this topic, if they tested it, I didn't catch it.
Thank You for this video! It was very informative. That's one of the reasons I use Custom Windows! So many unnecessary (for us) things on windows! There are others, like: Telemetry, it slows down your PC considerably too!
I never noticed much of a performance hit with this on or off, But you are right, this feature is going to be pointless for the majority of users out there so why not turn it off.
bro i must thank you sooo much for this info ,,, i had some frame drops and stutters even thought the svm was disabled from my mother board .. but after i enabled the svm and then disabling the coreisolation setting my pc performance went crazy .. no frame drops no stutters and i feel like my pc run in full power .. thank you so much bro
and let me thank you again before this option i couldenot OC my gpu more than 2740 mhz and the pc crash .. now i tried 2800hz it works like butter ,, idk if all this change is possible from this simple option but it worked for me
i thought there was something wrong with my used 6950XT because I always seemed to have stuttering problems, this made my games feel so much smoother thank u
I am going to try this later. I am getting nasty stutter whenever I teleport to another area in Genshin with my 5700X3D. I wish I left my PC on Windows 10. The stutter I get after the upgrade is annoying.
@@AncientGameplays I desperately need a clean install. I initially installed Windows 10 on this machine in January 2020. Since then, I kept updating, ran the Windows 11 update back about a month ago, and have changed the GPU twice, changed the CPU a month ago, and on my third monitor upgrade since then. The Samsung 970 EVO nvme is still giving me the same speeds in CrystalMark as it gave me when it was new and the Samsung Magician software shows it is in good health with good temps. Waiting for my GPU to come back from an RMA I have sent it out for.
There's little need for Core Isolation on a personal machine. If you have a bad program on your machine you're already screwed. It's more for shared servers and the like. Turning it off is fine.
Thanks for the info! Was excited to see if I could squeeze anything out my rig, but had it off already xD Might tinker with it later when I have time just to see if I perform worse with off.
If you do any security-sensitive work on your Windows PC (like taxes, storing private information, running your business, accessing websites you don't want your login leaked for, etc.), don't do this. Windows is generally vulnerable and these technologies are at least partially mitigating that. My recommendation is to have a dual boot - ideally Linux (for work) and Windows (for games) or Windows and Windows and to separate your work and privacy from your fun and messing around. Yes, it is a hassle but it's nothing when compared to identity theft (wanna wake up with someone taking huge loans in your name or making you the fall guy in some criminal enterprise?) or having your client info leaked, your data encrypted (be sure to regularly backup - and being it OFFLINE backup) or some other nasty issue.
I always disable anything Windows Defender related whenever I install Windows, exactly because of this. You never know what kind of setting is enabled for absolutely no reason which can affect gaming performance or the performance of your entire PC in some cases. I usually never get any malware so I don't need any anti-virus.
Much the same here, the most I use is 1.1.1.2 DNS resolving, because it blocks mal sites, and a firewall using portmaster. Can't get viruses if the places that have them are blocked, along with me just not being an idiot when downloading, clicking, or visiting sites. Plus portmaster blocks specific CDNs of common sites, programs, etc. So it's good for being a system wide adblock. (and when not on windows, well then nobara linux be doing the job just fine) (as for windows changing your settings and such, id recommend checking out christitustech and his windows debloat program, as well as O&O shut up to get windows to stop calling home and making changes so often) Yeah doing all these little config changes is why I barely touch windows now, too much work.
I wouldn't say it's enabled for absolutely no reason. What core isolation does is that it divides important processes in the PC's memory. Now where this plays a big part is in security, by isolating important pc memory processes malicious code has harder time spreading through your pc. Good security is like a good psu, you don't want to skip on it. I'd say that a small performance hit is always better than having your PC being infected as hackers have been getting quite creative and the issues may be coming from things you can't quite affect or expect, like the case with Apex Legends getting hacked and spreading malware.
@@DrunkenJoeh If you want security, use virtual machines on Linux and isolate your gaming environment from anything else. But that's not feasible for most people because of their specs. My point is, Windows has absolutely nothing to do with security. Malware can easily get past Windows Defender, and even with Core Isolation turned on, you can't do anything about it. I have done some RAT work myself and I can get past most AVs lmao. A digital signature is enough to stop the AVs from raising suspicion, and a RAT done properly that uses exploits to leverage permissions will be unstoppable by Defender. TL;DR, all Windows does is slow down your PC for the sake of saying it's protecting your PC. Sure it may protect you from regular malware, but that's the user's fault and if you're smart about the sources you download from and what you run on your computer, you don't need any protection. What we need protection from is exploits. Those need patches done by Microsoft, not Windows Defender or Core Isolation.
I LOVE YOU. I am so happy I stumbled upon this video. Linus Tech Tips needs to hear about this and popularize this, my FPS went up by 100. I feel like if I just got a new pc. I remember, when I first got my PC I had 400-500+ FPS in range in valorant, but after a while I had only 300. Turns out it was bc of virtualization, as I installed Visual Studio Code for schoolwork, which needed virtualization. THANK YOU AGAIN!!!!
Core Isolation is disabled when you turn of CPU virtualization in the bios. It's really only for corporate need. It does seem that we gaming enthusiasts need to shut that off while gaming. 5950x is a creature that will punish you for incorrect settings. This video has been a turning point in the saga.
Bro in warzone for at least the last year, I had on average 90 fps now I'm seeing insane numbers. 120 on average even hitting 150! This has unlocked my pc thank you.

Man as soon as I heard that virtualization needed to be off I knew I was fucked since I often work with VMs, but if this actually works even by keeping virtualization on you are a hero
it does
Core isolation page not available on my 5800X3D!!!Is there something wrong?
It means you have virtualization disabled on BIOS and are already at the max FPS you can get, which is GOOD!
@@AncientGameplays Same for mine, glad to know my 5800X3D is being pushed to the max properly. As always, great vid Fabio!
@@SpainSpace Thank you!
@@AncientGameplays Thank you, man!You're the best!!!
Yup on regular 5800X it's also off by default.
I just turned off the core isolation and I immediately see an increase in fps! I’m glad I found this video thank you 🙏
This sounds fantastic! But I'm not near my computer and I will probably forget about this so I'm just leaving this here as a reminder. Hi, future me!
Mine was already disable. Well, thats why my i5 10600k is performing miracles.
Yeah, it even takes coffees
Thanks for another helpful video.
I used to know every little setting when I worked in IT but not anymore so it's always fun to learn these things again.
Checked in windows and it couldn't open the page and i assume that means it's off in the BIOS and i actually am still pretty good. lol
Yeah, that's it exactly, you're good haha
Thank you. I hadnt even realised and as someone who uses an Android emulator, this had stealth turned on. Getting much nicer FPS ❤️
Ótima dica Fábio!
Você é o melhor 🤜🤛
Disabling Core Isolation is even more useful if you run local LLM models
I missed a graph comparing synthetic benchmarks, like CineBench, for example.
I'm going to try out your tip in a game I play a lot and which has a huge CPU bottleneck, which is Squad.
Anyway, excellent video as always, Fábio!
I did the same thing when Vondel was brand new on the 13900K and can confirm that it gave back about 20 FPS in that title
subscribed because of the solid not-well known fps tweak- disabled memory integrity thank you!
Lay an eye on my video section ;)
Interesting find, I wonder how this setting may impact the performance of some VR games, like VRChat, since that one is especially heavy on the CPU in some worlds.
This is something I wonder too. How much of a difference will this make in VRChat in VR (along with other VR games)
I found this feature a while ago. Logitech keyboard, camera and mouse drivers were preventing Core Isolation from turning on.
Good
Okay now that's a huge discovering
Nah, just something I needed to share
@@AncientGameplays I mean, this performance increase can be massive, it's a big deal for budget gamers !
You know what else is huge, your mom
I have never heard of this setting, amazing work.
All these big big tech channels with so many employees and no mention on this topic, if they tested it, I didn't catch it.
Mine core isolation is already disabled when I checked, which is sad news 🤣
Well, actually good ones haha
The funny thing is I turned this off yesterday to overclock my ps5 controller and I noticed better ram usage and fps was way better.
Thank you so much ❤ brother it's very helpful
Never clicked on a setting so fast! Thank you Computer Jesus! 🙏
Miss the result with 7800X3D 😢
True, but didn't have it on the PC right now
Thank You for this video! It was very informative. That's one of the reasons I use Custom Windows! So many unnecessary (for us) things on windows! There are others, like: Telemetry, it slows down your PC considerably too!
Mine was already off.
Good to know in any case.
Cheers mate!
I never noticed much of a performance hit with this on or off, But you are right, this feature is going to be pointless for the majority of users out there so why not turn it off.
Dang it mine was already off😢
bro i must thank you sooo much for this info ,,, i had some frame drops and stutters even thought the svm was disabled from my mother board .. but after i enabled the svm and then disabling the coreisolation setting my pc performance went crazy .. no frame drops no stutters and i feel like my pc run in full power .. thank you so much bro
and let me thank you again before this option i couldenot OC my gpu more than 2740 mhz and the pc crash .. now i tried 2800hz it works like butter ,, idk if all this change is possible from this simple option but it worked for me
well, other people found this out a long time ago, its been known for a while, but i guess its never bad to spread some awareness
Exactly the point
Niiiiiice!!!!!! Good find!
i thought there was something wrong with my used 6950XT because I always seemed to have stuttering problems, this made my games feel so much smoother thank u
Great to help! This means you still need a better CPU most likely
I am going to try this later. I am getting nasty stutter whenever I teleport to another area in Genshin with my 5700X3D. I wish I left my PC on Windows 10. The stutter I get after the upgrade is annoying.
If you haven't clean installed windows you should. Also, check your hard drives
@@AncientGameplays I desperately need a clean install. I initially installed Windows 10 on this machine in January 2020. Since then, I kept updating, ran the Windows 11 update back about a month ago, and have changed the GPU twice, changed the CPU a month ago, and on my third monitor upgrade since then. The Samsung 970 EVO nvme is still giving me the same speeds in CrystalMark as it gave me when it was new and the Samsung Magician software shows it is in good health with good temps. Waiting for my GPU to come back from an RMA I have sent it out for.
There's little need for Core Isolation on a personal machine. If you have a bad program on your machine you're already screwed. It's more for shared servers and the like. Turning it off is fine.
Exactly
Jesus Christ of technology 😂😂❤
Welcome to my channel haha
@@AncientGameplays My pleasure
Will add this to my win optimization routine. Since I have a gaming dedicated rig, I don't care about security. 😜
Appreciate your work man, Your channel is my go to when it comes to things like this
top demais, mano!
Obrigado, um abraço!
Ryzen 9 5900X + RTX 4080 Super I noticed a HUGE change in FPS. Thanks!
Thanks AMD Jesus 🎉❤
Thanks for the info! Was excited to see if I could squeeze anything out my rig, but had it off already xD Might tinker with it later when I have time just to see if I perform worse with off.
>Slower CPU
>tests a 12600K👍
12600K is slower, actually it isn't even that fast compared to lower end CPUs nowadays like the 5700X3D
id say its a slower cpu as well
@@AncientGameplays my bad i miss understood it
dude thank you so much, this provided smoother gameplay and looks even better thank you!
Great!
Jesus be praised
If you do any security-sensitive work on your Windows PC (like taxes, storing private information, running your business, accessing websites you don't want your login leaked for, etc.), don't do this. Windows is generally vulnerable and these technologies are at least partially mitigating that.
My recommendation is to have a dual boot - ideally Linux (for work) and Windows (for games) or Windows and Windows and to separate your work and privacy from your fun and messing around. Yes, it is a hassle but it's nothing when compared to identity theft (wanna wake up with someone taking huge loans in your name or making you the fall guy in some criminal enterprise?) or having your client info leaked, your data encrypted (be sure to regularly backup - and being it OFFLINE backup) or some other nasty issue.
subarashi
thought you were moistcritical on the thumbnail, but instead you test pc parts so now im calling you moistechnical
i love ur vids helped me so much keep it up pls. much love
I always disable anything Windows Defender related whenever I install Windows, exactly because of this. You never know what kind of setting is enabled for absolutely no reason which can affect gaming performance or the performance of your entire PC in some cases. I usually never get any malware so I don't need any anti-virus.
Yeah but even then, it will enable this shit sometimes
@@AncientGameplays Haha yeah. I wish Microsoft would stop enforcing this kind of stuff by default.
Much the same here, the most I use is 1.1.1.2 DNS resolving, because it blocks mal sites, and a firewall using portmaster. Can't get viruses if the places that have them are blocked, along with me just not being an idiot when downloading, clicking, or visiting sites. Plus portmaster blocks specific CDNs of common sites, programs, etc. So it's good for being a system wide adblock. (and when not on windows, well then nobara linux be doing the job just fine) (as for windows changing your settings and such, id recommend checking out christitustech and his windows debloat program, as well as O&O shut up to get windows to stop calling home and making changes so often) Yeah doing all these little config changes is why I barely touch windows now, too much work.
I wouldn't say it's enabled for absolutely no reason.
What core isolation does is that it divides important processes in the PC's memory. Now where this plays a big part is in security, by isolating important pc memory processes malicious code has harder time spreading through your pc.
Good security is like a good psu, you don't want to skip on it. I'd say that a small performance hit is always better than having your PC being infected as hackers have been getting quite creative and the issues may be coming from things you can't quite affect or expect, like the case with Apex Legends getting hacked and spreading malware.
@@DrunkenJoeh If you want security, use virtual machines on Linux and isolate your gaming environment from anything else. But that's not feasible for most people because of their specs.
My point is, Windows has absolutely nothing to do with security. Malware can easily get past Windows Defender, and even with Core Isolation turned on, you can't do anything about it. I have done some RAT work myself and I can get past most AVs lmao. A digital signature is enough to stop the AVs from raising suspicion, and a RAT done properly that uses exploits to leverage permissions will be unstoppable by Defender.
TL;DR, all Windows does is slow down your PC for the sake of saying it's protecting your PC. Sure it may protect you from regular malware, but that's the user's fault and if you're smart about the sources you download from and what you run on your computer, you don't need any protection. What we need protection from is exploits. Those need patches done by Microsoft, not Windows Defender or Core Isolation.
Nice tip dude! Gonna try it with my 9900K/1080 combo.
Ahah 15 min is not short😂
Wirh this amount of benchmarks? Kinda is
Got a 7800X3D + 4090, disabled Core Isolation, and I can honestly say I can't see any difference fps wise. Letting you know.
That's because you didn't test any cpu bound scenario
Thank you soo much. I forgot about this setting and it was affecting me
I LOVE YOU. I am so happy I stumbled upon this video. Linus Tech Tips needs to hear about this and popularize this, my FPS went up by 100. I feel like if I just got a new pc. I remember, when I first got my PC I had 400-500+ FPS in range in valorant, but after a while I had only 300. Turns out it was bc of virtualization, as I installed Visual Studio Code for schoolwork, which needed virtualization. THANK YOU AGAIN!!!!
Core Isolation is disabled when you turn of CPU virtualization in the bios.
It's really only for corporate need.
It does seem that we gaming enthusiasts need to shut that off while gaming.
5950x is a creature that will punish you for incorrect settings. This video has been a turning point in the saga.
Man i cannot understand these settings that worse your performance on windows
Bro in warzone for at least the last year, I had on average 90 fps now I'm seeing insane numbers. 120 on average even hitting 150! This has unlocked my pc thank you. I didn't find any advantage disabling virtualization so I just left it on. It actually seemed to have made things worse. Rx6700 and ryzen 5 5600x
