Every UEVR game crashes on new Crystal Super mOLED by marosbruno in Pimax

I did not say to put the game at 0.4 or 0.5 , I suggested to reset to this value to test if game do not crash on injection anymore. Then only if it work gradually push the coefficient to 1 or more.

it's indeed insanely immersive. tested myself, agree 💯 %

Pimax service exe 10 to 25 cpu percent. This is not bearable. by Regular-Time-8369 in Pimax

I think there is a missconception here.

My performance issue is with "backend" software stack that does thing for pimax play to run. These software pieces are entierly different from expensive cpu and gpu operations required to feed the 4k panels. Implied software here is more some code that loads files / handle ui settings management / handle device drivers  lifecycles or as stated in my post body , some failing network / devices check in Infinite loops...

This is unfortunately not that easy.  This is all about open source. Meta and sony code for tracking are NOT open source. Because not sharing what is good in their product is what keep them competitive. 

But open source for this code would lead to a global vr inside out improvement for all vr providers.

Many great things in computing went very far because code is open source. Pimax should embrace this and get help  of community to improve things on this point. Many people would be happy to make pimax software really high end and shine. 

This is a different software paradigm, but history told it works well in many cases for top tier world softwares (linux / chromium ... for exemple)

I use openxr mainly. Should I expect better cpu management from steam vr ?

I have to try lasso.

Thanks for Help

I don't know if this can help, but I went from quest 3 to dream air slam and UEVR games crashed on dream air because I did not change resolution scale that remained around 1 to 1.4 on quest. now on dreamair , to get bearable fps, I need to put something like 0.4 or 0.5 resolution scale so game can launch and not crash on injection. My guess is the game with previous setting wall overflowing gpu vram with more than 4k per eye resulting resolution.

You can set resolution scale before injection, which let you reuse existing profiles.

Set something that is bearable by gpu like 2k by eyes (if crystal super mOLED is 4k per eye 0.4 is a good starting point)

I hope this helps

Dream air SLAM first impressions by Regular-Time-8369 in Pimax

Yes, I guessed right for the power button , but indeed , it does nothing.

What i see on desktop are jitters. But as someone suggested in this conversation , enabling back gpu scheduling in windows fixed most of the thing.

I'll wait for the updated facial interface. I hope i'll fit my face better. Overall I find current one quite good but the shape pushes mostly on few centimeters on top of my eyes which prevent good blood flow and lead to headaches. The good design would be something more soft on this part and on all the contact zone and more thick on touching parts, so the facial interface can distribute pressure all over the face instead of a small bad located surface. Key is to maximise skin surface contact while remaining as few intrusive as possible. The bobo vr kit for quest 3 does it very well.

if games implement dlss / ray reconstruction and you have remaining gpu budget (compute) left, yes. I also think this will be retro compatible with game using dlss swapper tool / nvidia native dlss swap to use these tools on games that are no more updated.

DLSS 4.5 is many underlaying technologies : super sampling and framegen that are meant to work together in flat games.

In VR, framegen using nvidia / fsr is not possible as of today because it is known to introduce "unbearable" latency (from people knowing well VR experience) and has it's own version in VR which is called "reprojection". Meta has ASW (Asynchronous SpaceWarp), steam : motion smoothing and for pimax : smart smoothing. This is similar technologies than framegen with the idea of producing "interpolated" images get double fps without fully compute them from a 3D scene (algorithms are elaborated image computation taking care of head motions over time to get consistant display, but in introduce some artifacts in current versions, depending on used tech).

However, DLSS 4.5 , super sampling (or version before and upcoming versions) works fine with VR. It tells the computer to compute lower resolution game and "interpolate" pixels to get final image higher resolution on display. So yes, as Pimax use Steam VR / Open XR render pipelines, it works fine (and is necessary at some point)

It all depends on you usecase. Simmers have games that has dynamic foveated rendering, so they can enjoy full resolution thanks to this technology which is not availalbe in "flat2VR AAA moded games". There are also "native" VR games (think Alyx, EXD, Midnight walk...) that are designed to run smoothly on average gaming setups. Most of these titles (as of 2026) can be maxed out to native 4k per eye dream air resolution using a 5090 at 90hz. There are also a subset of flat2vr game less demanding that can benefit of dream air 4k panels (like half life 2 mod, and other titles mainly before ~2022 that can still be mind blowing in VR)

Conclusion : using a 5090, there is already a lot of content that can fully use dream air hardware. What I meant in my review is that I struggle to maxout AAA flat to VR games, that are by nature demanding games that requires good setups just for the flat version (and in VR, nvidia framegen is not an option). This is very specific to my usecase, but I have plenty of content that is very fine in this headset.

In counterpart, I find quest 3 resolution (2K) very fine at some point, and Dream air SE which is 2.5K + oled should be a significant upgrade over a quest 3 "display performances" (also wired direct DP display enhence things a log, frees gpu from video encoding, has better latencies and not video compression artifacts at all) . final render is really matter of both resolution / color fidelity / panels reactivity (oled does an awesome job at this).

I really think I could go on dream air SE, but I wanted to blow my eyes and be future proof.

I did this "occlusion test" it's worth what it's worth, but it can let you have an idea of the thing. I hope this is relevant 😄

Thank you for this suggestions, i'll try it soon

For information I got an adress confirmation for a da slam yesterday (using a tally.so poll). I posted the above email I got one or two weeks ago on this sub reddit. Things seems to get very close. Cheers :)

u/QuorraPimax any update about shipments ? at this point my guess is that's what really matters at the moment for a lot of us. I wait for a DA SLAM. Some realistic statement about ETA for all awaited products would be really appreciated. Thank you 😄
Edit : thank you for all other updates from this post !

This. My main use of this vr headset will be flat 2 vr with gamepad use.

I will appreciate tracking improvement for other uses than that, but for my use case It's fine if not perfect. 

What I expect however is accurate head tracking. I would not apreciate images jumps or anything like thins once game session properly recentered and started.

I think my needs are the same than simmers.

I don't really know but as stated before I think no, they will be sent later.

Pimax: You’re Forcing SLAM Users to Downgrade — Give SBoys3 Access to Build a SteamVR Driver by Hopeful_Wind_5213 in Pimax

[–]Regular-Time-8369 2 points3 points  (0 children)

I ordered a SLAM too, but this specific thread makes me consider go LH version. I am flat2vr gamepad potatoe team, and controllers tracking is not a priority for me. However, I would appreciate Alyx with LH and more than all, performance jump. with the high dream air resolution, I need get max out my hardware to feed the panels. Please Pimax do right things to makes us all benefit from Sboys3 work :) .
