Right, it is hard coded and it does not matter what you set. The idea is that if you run the monitor at a low (or lower) res, then the GPU can have more overhead to deal with the demands of VR. Does It makes sense? This may be good idea. I will try with DCS also…
This from Han over at IL2 BOS forums. https://forum.il2sturmovik.com/topic/12826-game-updates/ Go to update 2.009 to see the below post.
"Another tip we can give you to improve the performance is turning the in-game HUD off (H key). VR provides unique ability to read ‘real’ cockpit instruments at a glance, so try to use it! It can give you a huge performance boost, especially in complex missions with many objects. With HUD turned off, you can still see object markers (press I key to turn them on).
Setting the resolution in game settings to a low setting like 1024x768 or even less may significantly improve your performance in VR (VR resolution is fixed and won’t change, but the game will spend less time drawing its window on the monitor)."
I’m no expert. What do you think?
