and have noticed that since I have upgraded to the RTX, updated Pimax App, Drivers and DCS (2.8) and what all comes to gether, I have very high frame times compared to Ismael.
He has around half with the same CPU (mine is about 30-36ms in similar scenarios with identical settings in DCS) and again minus 2-3ms with the 5800x3d.
Now I know there could be about 1000 reasons, but since I count myself rather PC Tech affinitiv I wonder where his comes from. My I tried the Ryzen Master Settings for OC and Gaming to see if they change anything - nope.
I also have since I build the systsem RAM at 3600MHz and the correlating bus at 1800MHz.
So since its a diffrent HMD (similar Resolutions ) I would like to finde the cause for this large differenz. Especially since
HAGS ist like a handbreak for me in ST - I have to turn that off - causes stutters and enormous FPS reduction).
I have not tried how this behaves in MT - will give it a try now.
MT is definetly a gain for me, but now its the GPU that is limiting often (Small, 8K X, 4090, Using DCS Native OpenXR). But its like the first time that I can use it with almost 90 FPS in lots of the Instant or Training Missions.
FPS seem stable with HAGS now - but in flight I have extrem stutters - head tracking and also e.g. the FPS display of open XR flashes even though I get 90 FPS.
Is there a Pimax issue with Tracking and HAGS or is this rather OpenXR or DCS?
I currently have it running with pimaxXR 0.3.2 . Was a bit difficult, Windows itself blocked DCS functions.
If I were you, I wouldn’t change anything. MT is still pretty unpolished and with the 8kx brings me at time not enough pros over the cons.
Wait for a few more updates (DCS + pimaxXR if you’re not necessarily interested.
Edit: @BrziJoe - Oh yes, the fact that it doesn’t start for you could be because you have to expand the start parameters of dcs.exe.
( X:\xx\xx\bin\DCS.exe" --force_enable_VR --force_OpenXR )
small tip, if you can start, activate OpenXR Toolkit. You can switch off everything in it. Just because the software is running in the background makes the picture quieter. Maybe a framecap or something.
At the moment MT gives me slightly better FPS with identical settings.
But a few weeks ago I had more in 2.8.
Still have to experiment. But I’m still a long way from the 85FPS from DCS 2.5.
But, overall with MT the picture looks sharper. Less Ghosting. Only the side view bucking is a little more.
Yes piserver sucks with HAGS on…always has …causes mistimed frames. Interestingly if I turn it ON for Luke Ross’s mods, (at least for cyberpunk) which use oculus runtime, Improvement is 30% better! More oculus based game testing to come.
Update for me:
I installed the 0.3.2 PimaxXR Version - its unplayable for me - it keeps the frame Times almost the same but strangely only produces 8 FPS - I have no Idea why. I deinstalled it and reinstalled 0.3.0 and it was “fine” again. Only the Menu Sections are behaving strange (stutters) normal game is ok. Fog is bugged for me in Game - its a intransperent white layer in cockpit but fine whe doing outside view.
Now I need to get the DCS Update and see if that has changed anything . (HAGS still off - is it need on for 0.3.2 ?)
