Strange Bug in VR

[Cthulhus]

Hello,
I have a strange bug on DCS VR mode. I'll try to explain it ... First, I have this PC : I9-9900k, 32 Gig of Ram and RTX 2080ti, Win10 Pro. I have 3 VR headset : HTC Vive Pro, G2 and Vive Pro 2. Same issue on all VR helmet.

 

I have something like lags/judder. I have this issue from the game menu to the in game/in the plane, anywhere. (Setting the game in low setting don't do anything ! (so it's not a PC issue). Without VR all is fine and can play the game at 150 fps on high setting.

And the tricky part : If I set the game is out of focus, (with the red indication : Out of focus) all become fine in the VR headset ! (but ... as the game is out of focus, I can't use it ...)

 

I have the issue since 2/3 months and I found a partial fix but now not longer working. The trick was to switch from Beta to Normal version of Steam VR. (I had to switch each time I wanted to play. But now, it's not working anymore...)

 

Any idea ?

 

I tried :

• Full re-installation

• Steam VR re installation / full reset.
• Deleted the game data (settings etc)

• Updated the GPU driver
• Use other VR headset

 

I don't try yet :
• Windows reinstall

 

Thanks

it is the 9900K, I had the same issue and it wasn't resolved until I tried a different CPU.

 

After that I upgraded to 11900K

Sorry but re-installing windows won't fix it.

Ouch, hope I'll found a solution (or ED), the 11900K is expensive : 689.99€ on my local store... and their is no indication that i9900k isn't compatible in VR.

its not your CPU .. your CPU is fine...  i run DCS on an 9700k albeit with a better graphics card... you just may need to be realistic with your settings

realistic with your settings? It's not a perf issue, I still have the bug from the ingame main menu with low settings.

HAGS off?

HAGS off? What is it ?

Hardware-accelerated GPU Scheduler

do you have motion smoothing enabled correctly?

and if its not a perf issue, why did you think a new cpu would fix it?

[Convexrook]

Like I said, it was a CPU microcode issue with my 9900K the 9700K is fine.

This I have tested on my other 2 systems

8700K 6600k and my wife's computer 9700K.

 

To be honest it could be a multitude of issues, I was giving my experience with the issue and my solution. [Opinion]

I disabled Hardware-accelerated GPU Scheduler and I still have the issue... I contacted the support and they don't know what's is wrong...

 

I have this only with DCS, I play lot of VR games and no issues...

I don't think it's a settings issues, for example, I have the same issue if I set the game in extremely low settings.

Thanks, I'll try the STEAM Edition to see. I'll install a temporary Windows 10 on another drive to see if it change something.

The next Windows 11 will be free. I'll make the update and see... Or maybe that will be fix when ED will move on Vulkan.

 

Something broke my VR and maybe that will be fixed alone with an update of something... But now I can't use DCS ...

@Cthulhus Try to get rid of everything WMR related (drivers and WMR for SteamVR) on your system and retest the other two HMDs.
