I suffered badly with stutter in DCS 2.5.x. Previous versions were smooth. The ONLY thing that fixed it for me was @Kegetys' mod. https://forums.eagle.ru/showthread.php?t=215373
Flying the AV-8B on 2.5.2.19682, trying to get the TDC slew axis or down button to work and it crashed the game. Log attached. dcs.log-20180731-023836.zip
I spent some time looking at this yesterday. I did the whole delete save folder + clean + repair and didn't notice any improvement. Task Manager showed my GPU at <50% utilisation (often much less) and CPU around 30% when the game was stuttering and looking a mess. So it wasn't a limitation of my hardware.
I bumped the quality settings up (textures, MSAA etc) and used Process Lasso to set high priority for DCS, and locked it to 2 CPU cores. Et voila - performance issues solved.
I'm struggling too. 1.5.8 and 2.2 were fine in VR but even on low settings I'm getting massive lag in VR with 2.5 :(

According to this post you should be able to install SteamVR for WMR devices on Nov 15. https://arstechnica.com/gadgets/2017/11/windows-mixed-reality-headsets-get-steamvr-games-and-apps-november-15/
My understanding is Steam VR support will be added to the WMR devices by Christmas. I'm assuming this means DCS will support these headsets, but I'd love some clarification before I buy an Odyssey.
Struggling with missions 2 and 3. In both I've been hit and killed by enemy missiles. I switch to the wingman, return fire and the mission ends for breaking the ROE.
