Default Yet another VR Stutter Issue Thread (RiFt-S)

In the past few weeks my system has developed a stutter/ghosting issue that has become a huge annoyance.

The problem occurs as stutters when moving my head around in the pit. Not even sure stutters are the correct term, but it will be a rapid double vision or clunky movement. I have tried messing with the in game ASW(rctrl+numpad(1-4)) and it has not helped. What does, however, seem to immediately help the issue is Alt+Enter (Fullscreen to Windowed and vice versa). This fix is only temporary and after a few seconds I hit it again and it fixes it again for a short while. My FPS are not dropping and generally stay pegged at 40 with the current settings, even while the stutters occur. This has occurred with multiple aircraft (F16, P51, L39, Bf109, etc.).

Could this be an issue with my GPU settings? (Gsync? (i have a g sync monitor)) I have updated my GPU drivers since the issue started and nothing changed. I honestly feel like all these damn driver updates screw up more things than they fix so when things are running properly I try to avoid it like the plague. I do generally play music in the background and have browsers open and such. But I did this before to no effect on performance so I don't think this is it, just adding for transparency. Additionally, my GPU monitoring software starts the "OSD" every time I fire the game up and don't know how to stop it from doing so (EVGA Precision XOC).

Couple things I would try first.

Do a Repair of DCS.
Delete FXO and Metashader 2 files in Saved Games DCS directory.
Try again.

If issue persists, try doing the below:
Download latest Nvidia drivers.
Download latest version of Display Driver Uninstaller.
Disconnect Internet.
Reboot to safe mode.
Use Display Driver Uninstaller to remove the current Nvidia display drivers in safe mode.
Reboot to windows desktop (internet still disconnected).
Install Nvidia drivers you previously downloaded.
Only install the driver itself and PhysX - leave that other stuff alone.
Reboot again.
Connect Internet and give try running the game again.

If issue still persists, try a Repair of the Oculus software. Download the installer and run it, choose repair.

Thanks for the response. Will try the above. I have repaired the oculus software already this week, due to other issues. Not recognizing headset, multiple forced restarts, etc. That software is a different story and has had me looking at other headsets because I'm sick of its crap.

That is a little odd, mine has been solid as can be. I do see at times others having issues with it some.

I am experiencing exactly the same issue as you, and can also confirm that pressing Alt + Enter temporarily fixes it, then it goes bad again.

really annoying, and it hasnt always been like it, so dont know whats changed? Glad its not just me though.

I tried the above that dburne mentioned and no fix. Seems to be marginally improved, but not fixed.

Any chance the lighting in your room has changed any?

When you're using DCS in VR, I would start by reducing resolution to the lowest possible level. It shouldn't have any effect on your resolution in the Rift S. Lowering your cockpit display resolution to 256 will also boost performance, but if you spend a lot of time using your mirrors, you might not like how they look. Also, what is your pixel density set to?

If your GPU monitoring software behaves like other executables that autorun when you fire up DCS, you should be able to go to the .exe file for that and set "Run as administrator" in the compatibility tab. That should prevent it from automatically running.

Negative. I can try changine the lighting and see what happens, but if it's a lighting issue then logic tells me that Alt+Enter wouldnt help it out at all.

pixel density = 1.5

I also play with mirrors off.

Also, and I guess this is the frustrating part, up until a week or two ago the exact settings I am using right now were working perfectly. So something has happened somewhere in the matrix to screw things up. Either a DCS update, GPU driver update, or Oculus software update. And, unfortunately, software updates so often these days it's made it difficult to pinpoint the culprit.
