A couple tips if you do decide to do the oculus test Other than the PC framerates, I'd advise checking on the transmission framerates, oculus loves to take about 60-100% of the encoder just because it can (for contrast VD medium and steam link take about 30% on a 4070), making it impossible to get 120fps on lower end cards Besides runtimes which im not sure how they work, i can confirm that on a 1060 you could play beat saber at a resolution of 1920 120fps on VD, but using oculus you had to drop to 1400ish to barely achieve 120fps I was also using oculus killer which honestly didnt feel like it did much, but i also found a fork of the project that has received many updates and i think the performance is better(?) There are a lot of variables, but in summary i advise to test VD Steam link Oculus direct Oculus steam link Oculus killer (the updated version from the fork) Also important to check on the transmission framerate

I use Steamvr with my Pimax Headset exclusively because of exactly the reasons you show here. Thank you for making a Point. There is a lot of confusion around when G2 or Q2 users change to a Pimax Headset. A lot of outdated info too. Well done!

Quest 2 / 3 / Pro with steamlink is pretty much the same as a steamvr native headset like a Valve index or Vive pro no?

Thank you, you black shadow adviser . That is an excellent piece of information. The only thing I wish to have in the content is the advice for DCS VR and IL2VR since this is the reason for doing VR games.

Wondermelon

The main reason I try to avoid steam is the bloat and stacked launchers. Some games don't play at all.

I didn't know Steve GN had a child. Immaculate conception! Praise be!

I hope that thete can be a better setup on Steam VR for mist heafsets..eg..where it can detect yi headset and automatic set it for user😢😮

I always use Opencomposite with my Pimax and SteamVR with my Quest 3. I only use the Pimax for Flight Sims and Opencomposite gives me a far better frame rate than SteamVR can when the graphics settings are high. I do this because the Pimax has far better clarity for viewing long distance. I use the Quest for anything else, mainly FPS type games, and Steam VR gives a good performance with this type of gaming.

Please do a quest comparison!

cool and awesome. an overview on the options on oculus would be very interesting too

Honestly, your results probably have more to do with the Pimax software, and I think your video title ought to reflect that. It‘s quite known to be unstable for no apparent reason, and with OpenComposite being developed by an unaffiliated and non-profit third party, it‘s likely the two softwares are not playing well together. However, with your hardware, the difference should be somewhat negligible anyway, even if OpenComposite did work as well as it does with the Quest(s)

The Pimax crystal looks crazy,I’m sure it is amazing through

Very good video, appreciate the work you put in here! I would've liked to see VRChat performance though. Single user instance in the UDON Benchmark world would probably be consistent enough to post. So if you do a Quest 3 video, perhaps you can put that in there.

A Quest 3 version of this video would be awesome. Personally I use VD and I'd be very interested to see how that stacks up

I would love to see a video like this for the meta quest 3 headsets vs using steamlink\airlink or virtual desktop this is pretty interesting.

To the man in black (man, that suit looks itchy, LOL) thank you. I'm supposed to get my PCL late tomorrow, but with my G2, I use SteamVR (OpenVR) 99.5% of the time, only title I have which gets the OpenXR treatment is MSFS and the rare times I play iRacing. As for open composite, I can't say I'm a fan of this approach, the way I look at it, either a title has native OpenXR support or it doesn't in which case I use SteamVR. Open Composite just looks janky and a pain in the butt! Again, thank you for the video, a bit of a eye opener (pardon the pun 🤪)

Fab. Noticed something was off with Pimax XR and OpenComposite too but MSFS always made me question myself cause it was noticeably better perf with Pimax XR. Nice to have some numbers to see these differences across titles. Will keep Pimax XR for MSFS and Steam for everything else. Bit of a pain switching between everything... c'est la vie.

What help is supersampling and removing all AA

Great gains with bypassing SteamVR, the difference between 85fps/90fps is a difference between playable and not playable. So I don't agree that its an performance difference to ignore. If you want max. performance the way to move forward is OpenXR toolkit with maximum tweaks with SteamVR bypassed. You need the toolkit for max. performance, so its not a choice of openvr or openxr, its SteamVRs OpenXR runtime or opencomposite and then the difference is significant! You forget that most important fact in your video. SteamVR is and stays as terrible as it ever was.

Curious if theres a relation between (mostly) GPU and CPU bound games, what if we have a NVIDIA drivers situation, where the drivers use more cpu resources thus reducing its performance?

I love this!!! There definitely needs to be more videos on this so we can save fps anywhere we can even with a 4090 so we can hit a fairly consistent 90fps in all games

Im so confused about VR 😂

What happened to your mic omni? it sounds like it's buried in sand at the bottom of a pringles can

Excellent in depth info in a side of the VR world that few people go down. It’s very time consuming, not mainstream and at times aggravating. But that’s the life of being an enthusiast! Props to you for doing this and sharing so others can learn. I’ve done my own tests using these programs with various headsets over the years and I’ve always ended up staying with SteamVR. As a VR only live streamer/creator, the tools on SteamVR make life easier. But the performance difference never seemed to make a big difference. It’s great to see your results! Thanks again for doing this and sharing! Had looked forward to this one since you had mentioned you were working on it. Cheers Omni! PS, mbucchia is the dude!

Is there a way to actually test VR performance without having the headset on your head?

Doesn't foveated rendering and culling outer mask used with openxr flips the table completely?

why man's gotta wear a gimpsuit for the analysis video

Ok, subbed because this is a lot of work and you nailed it.

Your annoying voice and the great benchmark earned a sub from me.

I mainly play using SteamVR for most of my VR games, but one game that really sucks with SteamVR, which I cant explain why is ACC, thus for ACC, I only play using OpenComposite with OpenXR toolkit which this game is very stable with... like I said, I cant explain why or ACC just sucks in VR.

It looks like the Pimax Crystal is set at 120 Hz refresh during the testing. What happens if you set the refresh to the 1% lows, such as 60 Hz or 72 Hz? Will the variance stabilize? Also, in IL-2 there is a significant change in the appearance of the game after making changes in XR toolkit. Thanks for the effort to make these comparison tests.

Quest 3 version, please.

Yes would very much love this done for Quest headsets

Have you tried it with UEVR?

How to use OpenXR SteamVR instead of OpenXR PimaxXR?

I'd like to see this video done with a Quest 3, If only so I know which I should be using.

Great info! Thanks.

Thank you so much for this! Finally confirmed my suspicions. Great work, you are needed on the VR scene.

Well, I don't care about 5% -/+ performance gains. What I know is that some games I run through SteamVR will crash (themselves or SteamVR itself), suddenly pixelize or tear like my headset had been smashed against a wall when they do fine through AirLink (although I hate the UI).

Will psvr2 work with open composite and perform better?

Disconcerting to be given information by a human fly....

Very interesting... I play DCS and have felt the performance was about the same either way. I prefer OpenVR as I can run overlays and also the Motion Compensation for OpenVR for my Motion Platform seems to work better than the one made for OpenXR. I plan to test this myself down the road but your video seems to have answered the questions I had for now. Thanks for doing all the work on this, I really appreciate it.

Some really good info here, thanks for doing that and sharing

Do you have to use PimaxXR in order to get dynamic foveated rendering to work?

But lets get our semantics straight. Pimax does not even have their own native OpenXR, you are usaing PimaxXR which is a tool built by MBuccia and runs without steam but not technically native.

The chart from Mbucha (sorry I don’t have the spelling handy) was something I’ve wanted to see for quite a while, and your explanation of why Open XR is something I hear people asking for all the the time makes sense - in theory. It was great to see your testing numbers to see that one vs the other isn’t always the best answer. Thank you for your work and the new lighting is cool.

I am not doubting the compatibility issues with Quest headsets. That being said I've only encountered issues on one single game not running properly in steam VR which was TWD:SS

Thank you Omni for doing these benchmarks! Nothing else like it for VR.
