I had a similar issue. Launching the game as a VR session with the Skate Zilla 'DCS Updater/Launcher' fixed it for me.

Nealius - Were your drivers up to date prior to installing 528.02 or had you skipped a few updates? I've taken a performance hit with my Q2 - crazy screen tearing and stutters - to the point where it's back in the drawer. I had it running sweet as a nut, even in multiplayer but something just happened and I can't pin it to anything I've done other than the occasional driver update. Have you tried the latest 528.49? I'm about to as I've nothing to lose!

Update: OpenXR is now working for me. I launch a VR session via the Skate Zilla DCS Updater software. Under App.Settings, select Rendering Driver as SteamVR API and then launch the VR session by clicking 'VR On' from the left side options. This was after running the 'Per Game' install of Open Composite discussed above. However, having now got OpenXR working at circa 52fps, I have to say I am now returning to my original set up without Open XR as explained in the link below. I get 72fps with this method.

Is that the case even when I don't have the Steam version of DCS?

Update: No joy I'm afraid. I've done the per game install but still can't get the OpenXR menu up within DCS. I've changed the F2 key bind several times both with modifier and without to ensure there are no key mapping conflicts. I have found a log file in the Open Composite folder which says: [2023-01-20 20:54:12.204] Config::Config:207 - Checking for global config file... [2023-01-20 20:54:12.205] wini_parse:172 - No config file found at E:\DCS World\bin\opencomposite.ini [2023-01-20 20:54:12.205] Config::Config:226 - Checking for app specific config file... [2023-01-20 20:54:12.205] wini_parse:172 - No config file found at E:\DCS World\bin\opencomposite.ini Any ideas? Many thanks in advance.

Thank you for replying. I did not do the above so will give it a try, though as DCoffey mentioned, the link is down at the moment. I'll post results for community feedback.

Recently installed Open Composite and OpenXR Toolkit. Works a treat in MSFS but I can't get the menu to pop-up in DCS. DCS is listed as one of the recognised applications in the Toolkit and the blue box is ticked. I've cleared all F2 and Ctrl keybindings in DCS just in case there was conflict in the background. I followed the install guide, repaired DCS and so on but Ive clearly done something wrong but not sure what as it's working in MSFS. I've searched historic postings but can't find any similar topics/experiences. Any ideas? Hope you can help. I have a Quest2, MSFS is Steam and DCS is non-Steam.

My list of multiplayer servers is only 9 in total. I've no filters on and have checked my firewall. Not changed anything - just returned from holiday and find this. It will be a local issue I'm sure. Anyone had the same and what was the fix please? Hope someone can help. Cheers guys.

Just for general community info........ I've just installed the new Nvidia driver 511.23. I've not tried it under VR conditions or played with any new features yet but in normal 2d it's a 0.6FPS drop (80.2 to 79.6) which is okay by me. I haven't noticed any onerous or concerning differences e.g. stuttering, flickering, etc. Test conditions were a simple mission created for a Hornet at 1,000ft on approach to Senaki using FRAPS for benchmarking. Logging started at the exact some point in the terrain for each run and an average of 3 runs before and after install of the drivers. Previous driver was 497.29. PC is i7 11700 + 3070 + 32gb 3200hz ram

My tech skills are limited to what I can find on Google rather than hard core experience but I have been chiselling away at my Q2 settings. I find the Ocullus software manages things pretty well now and no longer use OTT. I have MFAA on in NVCP and all looked pretty good apart from the stutters. My DCS is on an M2 drive and I only have 16gb ram (32gb arrived today ). I noticed my stutters coincided with massive access to my Barracuda disk drive i.e. 100% load. I therefore moved the page file to the M2 Drive and that has stopped the stutters for me. Rest of PC is i7 11,700 and RTX3070.

Do you have Terrain Object Shadows on? I’ve found the shadows form a big part of the shimmer so I’ve turned them off. You don’t notice they’re gone but certainly notice less shimmer.

+1. Oculus software tweaks give me the best visuals and performance now. I run at 72hz with the slider one step off the far right whatever that resolution is. No longer use OTT but do enable sharpening in ODT. I made these changes after watching more recent You Tube content (you gotta be careful of old/outdated content on there now) that suggests OTT has been overtaken by Ocullus software advances in 2021.

I turn off Terrain Object Shadows because a great deal of the shimmering is the shadows on fences/trees and not the fences/trees themselves. Looking at your settings, it looks like you’re doing that? The only other thing I saw an improvement with was turning on MFAA in Nvidia Control Panel.

I experience a FPS drop if I go into the theatre map and then return to cockpit view. Not all the time and only in multiplayer. Is there any action like that you are doing that is perhaps prompting the drop or is it totally out of the blue?

I must have watched every You Tube video on OQ2 settings for DCS. I was pretty disillusioned shortly after Santa delivered my OQ2 but quite happy now. What I’ve learned so far: 1. According to many, Ocullus app runs things pretty well these days. I have my device settings as 72hz and the slider one step off the furthest right position. I find cockpit text is clear and is marginally sharper than any resolution settings I tried in OTT and DCS. 2. The shimmering annoyed me but on closer inspection during all the FPS tests I did, it’s primarily the object shadows that shimmer (around trees, etc). I’ve therefore turned off Terrain Object Shadows and am finding it much improved. There’s quite an FPS boost too. 3. I have Visib Range on Medium. If you slide ‘Tree Visibility’ to max, it masks the ‘trees sprouting out of the ground in front of you’ characteristic of low and medium Visib Range settings. 4. I no longer use OTT having watched a few videos suggesting the advances in the Ocullus software this year have pretty much made OTT redundant. Don’t shoot the messenger but I tend to agree - I’ve personally not seen it add any value despite many different setting changes. 5. I enable sharpening in ODT. 6. My Nvidia Control Panel settings are default apart from MFAA enabled. This improved what shimmering remained for a very modest FPS hit. It kinda induces an MSAA x3 level if there was such a thing in DCS - a nice halfway house. Hope the above points are of some use to those of you out there who, just like me, got a VR headset for Xmas and entered a whole new world of pain! My PC is an i7 11700 + RTX 3070. Happy flying!
