Lag and flicker in VR since 23.12 -> 2.7.9.17830

[Buzzer1977]

With todays update i got several multi second lags in VR on multiplayer. The picture just vanishes and i'm in the SteamVR environment with the "DCS wait" logo until a few seconds later when i'm back in the cockpit. It wasn't as bad with 2.7.8.16140, but 2.7.9.17830 is really really bad.

I too am getting intense flickering during VR play since the update. The display seems to flick between the DCS display and another display  but the flicker is too quick to make out the image on the other display.

I have noticed it particularly during low level helicopter flight when I get close to a large building or monument. The flickering continues even if the game is paused. The attached track shows it well on my machine. The flickering starts just a few moments after I start to hover near the coloured monument in central Damascus. The track plays OK in non VR playback but the flicker is reproduced on playback in VR.

I have an Oculus Rift S with a 3080 graphics card. Drivers 496.76 (release date Nov 2021). My other VR games are working without any issues so this definitely seems to be a DCS issue. As mainly a helicopter user it is dramatically affecting low level game play.

This youtube video of my VR mirror shows the flickering that I am describing in VR. This is the track I posted above. The flickering starts at about 1 min and 30 seconds into the video. The same track plays back without any problems in non VR.

I have noticed the flicker only occurs on looking forward out of the cockpit. I can stop the flicker by looking outside to the side or down into the cockpit. Very strange!

I have the same problem in VR on a valve index mostly with warbirds looking straight through the prop specially on the ground. Happens with other aircraft but not nearly as bad as it does with warbirds but haven't tried helicopters yet. If I look out the sides of the cockpit or down at the dash the flickering stops. It also only does this on what would be the UI area.

Unlikely, but its worth trying if you don't already have the latest firmware installed for your Reverb G2

Fix and enhancements:

Resolves a potential issue where displays may flicker or go black when playing certain titles at high volume levels.

You are correct it mainly seems to be when looking at UI area. This video shows it quite well when the game is paused and you can see the UI. The flickering almost always seems to happen when the main focus of view is on the UI area and goes when looking elsewhere. Please note the VR mirror does not give the same FOV as the headset. In game it is even more obvious the flicker occurs on looking forward.

Had already installed the firmware back in april when it was released. No new version was released since.

Any other updates since (or shortly before) the update (Windows, GFX, others?), or configuration changes (e.g. within NCP)?

Nothing on the system recently. The only recent change was DCS 2.7.8.16140 to 2.7.9.17830.

This fix posted on the 2D bugs forum seems to have worked for me . Hope it works for others as well.

How do you check your 6 without mirrors?

Mainly fly helicopters so checking six not that important for my gameplay

Obviously though the fix is just a temporary solution until ED make a permanent fix to the bug.

Turning the head makes the stutter, flicker and lag even worse.
