HP Reverb G2 - STEAM VR - VR headset timing issues

Product: Star Wars: Squadrons
Platform:PC
Please specify your platform model. PC
What is your gamertag/PSN ID/EA Account name? CA01-PAINLESS101
Are you playing in VR? Yes
Which VR Platform are you using? Steam VR
Which part of the game is the issue happening in? Practice Range
What were you doing when the bug occurred? Step by Step detail is helpful. Reverb G2/ 10700k / 32gig / RTX3090 - 90htz Problem - inconsistent stuttering from inside the headset. Using the Steam VR - Developer features - and using the colored performance graph that you can set to be on from inside the headset through STEAM-VR, you can intermittently (but frequently)see dropped frames. I have spent tens of hours tuning this, and this seems to be a problem with how the headset is rendering and timing frames back and fourth between Steam, the GPU and SW-Squadrons. Lowering settings seems to mitigate to an extent, but we should not have to do this. Changing htz to 60 also seems to alleviate the issue somewhat- but lowering htz this far gives me a headache! This definitely needs attention and needs refinement and a patch. Please fix at 90htz. Needs a patch. In comparison, I have Rift S, that does not do this. Please show the newer headsets (like the Reverb G2) a little love and develop a framerate/frame timing improvement patch. This was never optimized and its sorely needs it.
Where did this issue occur? Please include menu name or in game location. happens all the time, Use the Practice range as an easy test.
When did this happen? (dd.mm.yy hh:mm) 1/25/21
How often does the bug occur? Every time (100%)
How severe is your issue? Can play, but it's highly frustrating
What happens when the bug occurs? stuttering - annoying juddering Steam Performance monitor overlay start showing dropped frames - turns from Green to Red
What do you expect to see? smooth FRAMES - Green on performance display
Which ship were you playing? If not applicable, just answer "no" or "none." NA
What components were you using? NA
Which customizations (if any) were you using? NA

please see above

  • I see some stuttering as well at 90Hz on my RTX 3090 and HP Reverb G2 when Supersampling in Steam set to 100% (2x3172x3096 resolution). If I set it to somewhere between 50-60% seems to run smoothly. Keep in mind, that compared to the Rift S the Reverb G2 requires the video card to render a much higher resolution, one that will make it very hard for even our "mighty" RTX 3090s to push out 90FPS which is required for 90Hz (one can enable Motion Smoothing to get rid of it, too, but then all GUI elements like crosshairs, indicators, etc.. will have severe ghosting which again makes it nigh unplayable). 

    From your dxdiag I see you're still running the Nvidia 461.09 drivers that have bugged VR and don't include the VR stutter fix from the Nvidia 461.33 Hotfix drivers yet. Have you tried the Nvidia 461.33 Hotfix drivers (use Display Driver Uninstaller to clean the system of any remains of older drivers before installing them)? Also, keep in mind that running VR with GPU monitoring tools (anything from Afterburner, Precision, GPU Tweak, GPUz, HWInfo, Fraps, fpsVR, Steam VR Perfomance graph, etc..) will cause these stutters even with the Nvidia 461.33 Hotfix drivers, a fix for these will come in a later driver, so it's best to disable any such tools to test until Nvidia releases a new driver with the fix for that.

    That said, some things do indicate that there is a problem with Squadrons and 90Hz headsets as well.

    Also, there is a weird Bug with Squadrons, where Squadrons runs way smoother in VR whenever it isn't the active Window/minimized.

    It would be nice if Motive devs could investigate and see if they can improve performance.

    @Cave_Waverider I installed the 461.33 Hot fix last night. Not much (if any) of an improvement.

    Tried the motion smooothing but the ghosting is horrendous.

    I don't think this is a limitation of the 3090 and its ability to render frames. The Frames, at a certain resolution and detail level, are being created in time and a good FPS is being maintained. Where the stutters are coming from, are at the Steam VR level, with a bunch of "re projections" occurring. You can see this in action if you look at the advanced frame timing info in Steam VR.

    I do believe its a bug in the timing of the software between Steam VR & SW-Squadrons.

    The Frame loop timing is off creating the stutter. You can see it in the read out of the tool. I really believe its that "simple".  (Simple meaning its not a config setting or performance limitation, but rather a bug that needs to be fixed. (not so simple for the developers to figure out Im affraid)

    no improvement for me usng 461.40 w/nearly identical hardware.

    Ive also spent tens of hours trying everyhing possible, inlcuding kinda crazy things like swapping out my primary monitor (120Hz Gsync). It seems to have no relation to load/performance-resoltuion/steamSS settings dont really matter at all. (nor do nvidia settings or any of the many other things Ive tried)
