DPVR E4 Review | Does a Quest 2 With a Displayport Even Have a Market in 2023?

- Опубликовано: 16 июл 2024
- I got sent a product for review purposes for the first time and so we're taking a look at the DPVR E4 today. A headset aimed at the budget to mid-range segment and offering uncompressed PCVR via DisplayPort, when that seems to have been largely abandoned on recent lower-end HMDs now.
This headset took some notable shortcuts to remain budget, but there's also a few things it does well.

Looks like a good option for a PCVR newbie but given its archaic design it’s way overpriced. Probably should be priced around $299. Thanks for your always great reviews mate and best cheers from Australia.
I always feel the need to comment on every DPVR E4 video that I tried it and it was not working with my IPD (about 70mm). A Quest 2 on the wide setting looks absolutely perfect and comfortable, but I have the same issue with both the E4 and also the Rift S. No amount of software adjustment can eliminate the eyestrain, and I had to return it. Other than that, I thought it was a relatively solid headset and the Displayport + slight lens upgrade made the displays look much more impressive than they ever did in a Q2.
That is the exact kind of thing I was worried about would happen and a big reason I'd have trouble recommending it even if everything else was right. Fixed hardware IPD is just playing with fire. Sorry to hear that.
thx a lot for your comment ( i was looking for this info everywhere on reddit ), I have the same ipd as you and i was wondering about buying this headset, Ill probably go with pico neo 3 link or hp reverb g2
The DP, airlink and VD comparison was super interesting. I have felt like wireless compression has been overstated for the last year or so, it was bad 2 years ago but the last while (especially since the big VD update) it really has been impressive.
Yeah it's honestly rather amazing how good it looked. There was still SOME compression in certain situations, but you'd have to really pixel peep or know exactly what to look for to find it sometimes. Really impressive how far it has come.
Granted, these resolutions are a good bit lower than the apex of what we have with stuff like the Aero and Crystal so maybe it'd show more cracks on something like those, but even still. It's quite good considering the bandwidth limits is orders of magnitude lower than a DP cable.
omniwhatever you have been killing the youtube game this is the best review of this headset ive seen and i really appreciate the benchmarking with gpus you do have you thought about standardizing the way you benchmark vr its so hard to get back to back tests reliably
VR Benchmarks are hard but I'm not really sure what you mean or would expect when it comes to 'standardizing'. It's hard to do comparative 1:1 benchmarking, or close to it, because even slight head movement or enemy placement could lead to hugely different results.
A showcase is easy, a benchmark to compare to another one is harder and I usually try to pick stuff with minimal movement(Like Saints and Sinner's intro) or has minimal variance with some replicable cutscene like behavior, such as with Alyx.
i plan on buying it next paycheck
Dude made his pimax crystal his personality
Because of the flimsiness of the silicone interface, the headset has to be tightened so much that you can see the entire borders of the screen, it's either that or a lightbleed fest if the strap is too loose.. That is a problem often overlooked by reviews, but seeing the edges of the screen IMMEDIATELY takes a person out of immersion.
I've also noticed that even with the lowest display settings (4k 72Hz) the headset feels like it's going to catch on fire, so the fan runs at 100% constantly. And the fan is loud, so loud in fact that every head movement results in the fan blades hitting the casing and making an awful scraping sound.
The controller tracking is fine, but the headset tracking has an issue where every second the playspace gets moved around a tiny bit, this is very noticeable when looking at things up close, maybe higher room brightness might fix the problem though.
Also fun fact - the old Windows Mixed Reality headsets featured a flip-up visor, but every time it was used it would cause the hinge to quickly degrade over time, essentially the headset would fall right out of your face. I wonder if the questionable build quality of this one will stand the test of time.
This device is way overpriced and doesn't have enough good features to counteract the bad ones, I had hoped to finally retire my HP mixed reality headset, but it looks like I'll have to wait even longer.
They sent me a headset to review as well, told me to send it back and they would cover the shipping because i had nothing good to say about it. They have yet to respond since i sent the headset back 2 weeks ago. It's hands down one of the worst VR experiences i have ever had.
Do you notice any CPU bottlenecking on resident evil village using Quest 2 compared to the DPVR? Maybe I am goofing something up but at the same res and hz, my quest 2 can't get past 60ish fps no matter how low or high the resolution is, but on my G2 I can easily hit 90. I noticed in FPSVR that my CPU stays in-between orange/red while my G2 stays somewhat comfortable in the green zone. Do you think this is due to the encoding? Or am I goofing up somewhere?
Nope no issues here on either. The Quest 2 with Virtual Desktop actually consistently performed a few % better than the DPVR did. On the new rendering method and upscaler branch. Didn't try the current non-beta branch on these. You running the Quest 2 in 120hz mode? MIght be getting forced into reprojection/motion smoothing.
12:08 do you know how to install Resident Evil 8 on PC for virtual reality? I wanna install this because I’m buying the DPVR E4 but I’m also waiting for a BigScreen beyond and playing resident evil on a BigScreen beyond with fresh OLED displays and an insane resolution would be insane. Plus I never got to play resident evil 8 in vr and I would like to be able to start playing games that are actually good instead of games on meta quest that are pretty much the length of iPhone apps for the most part
I can very clearly read line 8 on a supersampled Rift S without using CAS or any sharpening. That's very interesting considering it's a much lower PPD headset.
From FIVE meters away, which is the furthest point on the mat? I have some trouble believing that. I could readily believe it from closer than that since legibility rapidly improves as you step closer.
@@Omniwhatever Of course, actually even a little more. The gray circle was sitting before the measuring line even starts.
I set the in app supersampling to 2.0 so I assume the res was about 3500p.
I really have no reason to lie about it. Just found it very interesting.
I'm not surprised quest is worse since that's compressed and I did a test like this myself but I'd expect DPVR4 to be way sharper than that.
@@b00rak Are you talking about the resolution adjuster within TestHMD itself? In that case, it could depend on what its multipliying vs SteamVR here. If the 2.0 figure is meant to do x2 the total pixel count, then(for example's sake) 1000x1000 would end up as 2 million pixels(Instead of 1 mill). However, if the 2.0 refers to each axis INSTEAD, and you're multiplying the 1000 figure instead of the end result, you'd get 2000x2000, which ends up as being 4 million pixels, or 2x the other result.
I don't know what TestHMD uses for its resolution scale but depending on how things are done could explain the results.
@@Omniwhatever Yeah, I'm pretty sure it multiplies it per dimension, I think only steam does it based on total resolution.
Regardless, it shows you how important high supersampling is if it can make a considerably lower res headset sharper than the higher res one.
@@b00rak Perhaps, but there's also some more factors to consider. I've been rather underwhelmed by supersampling even to very high amounts and there's a bit more to what gets you your clarity than just resolution.
Resolution isn't your only factor in clarity. The Rift S is a smaller FoV headset, having under 90 degrees rendered FoV horizontally and only 94 vertically, vs 96x96 of something like the DPVR E4. A small FoV headset can have a higher PPD than a much higher res one if the image is focused in a tigher area. The gigantic res of the 8KX, 3840x2160 per eye, still ends up with it being LESS sharp than the Reverb G2's 2160x2160 per eye despite the G2 being a much, much lower res headset. Or take the Crystal having the same total pixel count for the panel resolution(2880x2880) but it's leaps and bounds sharper than the 8KX because it's focusd in a much tinier FoV. And as you increase FoV even slightly the amount of pixels you need for a similar clarity goes up drastically because of how something like surface area works.
The DPVR and Quest 2 are quite a bit higher res than the Rift S, but they've also got a moderate FoV bump so the clarity isn't going to scale totally linearly with that, even if they'll be a sizable improvement still.
Have you ever tried a Samsung O+ ?I am surprised nobody talk about it .With vrss ON I prefer it to my HpG2. Deep blacks, great vertical fov and per pixel illumination.
Can't say I have. Have used OLED HMDs before but eeeeeh wasn't blown away.
I have a g2 I don't like it ,I am not I should spend for a crystal when I don't like lcds.
I'm here because I have an O+ and looking for a reasonable upgrade. I'm surprised you prefer it over the g2
@sodapopinksi667 The od+ feels like 4 times the fov of the g2, when in a dark room the g2 look like a horrible Grey.VRSS or fixed foveated rendering improve so much the performance and the definition.The only problem I found on the od+ is the facial interface. I can see the screen door in the g2, I can't in the od+. All lcds feel the same to me.You can improve a lot the fov check the size of the lenses. Just enlarge the bottom of the face gasket until you can get very close to the lenses.
what are you wearing?
I want to find a cheap headset that doesnt use meta. Guess ill keep looking.
people scream for wireless vr, wifi then became the saving grace.. untill you have games with foliage and then you realise, that leafs, gras and smal moving objects, are the bane of compression. i dont get, why usb connection have become the norm. if you have a connecter for wired pcvr anyway, then use DP, cant be that much of a parts price difference. even pico according to the rumors, only puts DP on the pro maxx 999 dollar headset, with an insanely high res that needs the hardware to be able to run 3500+ per eye but the pro and the regular one, only use usb
That is a stupid question. There will not be a Quest (1,2,3,any) with Display port. So you might as well ask Does a cow with 3 assholes have a market.
549 USD 💀
Even without the noticable latency that comes with link / virtual dekstop,
thats a very hard sell.
This would be competitive at 250-300
$549 is cheap. think about all the stuff you gotta do to a quest 2 to get it comfortable, you still gotta buy a router etc etc
@@D-money813 I mean, 299 USD + 50 (Headstrap) + 50 (Quality Link Cable) is probably the better experience for 150 USD less
I don't think it'd have to be THAT cheap, but yeah 549 this late into 2023 with the current compromises I just don't really see it being that compelling an option outside of a very specific market. You could buy the Quest 2, a wifi 6 router, the Vive DAS+adapters, and come out to about the same price, perhaps a bit less.
Maybe if Virtual Desktop didn't exist too, I was shocked how good that ended up being with 10-Bit. Airlink was a noticeable downgrade.
@@Omniwhatever i didnt see the price drop but I will say this, buy the dpvre4 and you are not putting money in zuck's pocket. that fact cannot be overlooked AND you'll be supporting PCVR
@@Omniwhatever Glad VD is working well for you mate. I can't see any differences in performance using VD (+4yr user) and Air Link with my Quest Pro/rtx4090. Probably a systems/settings thing. Actually, msfs has slightly better performance with AL because VD it needs to run through SteamVR's OpenXR. Pretty well the same running any Rift store games through VD but most of the differences are not noticeable, to me at least.
Aside, I've measured the fps performance loss of my Hybrid PCVR headsets vs dedicated my DisplayPort wired Vive Pro to be about 10% lose. Lower latency with DP (Probably around 20-30ms less). With my high end win11 pc (i913900/rtx4090) I don't really see any significant differences.
