VR optimization guide online or in-game

[Seba]

we seriously need a comprehensive guide what settings are tasking the pcs the most. i own 3080 with i5-13600, and i can barely play on valve index through steamvr on lowest settings with everything off

i launched it through vulcan. tried turning off shadows, im getting weird shadowy artifacts if they are enabled, from 120 on lowest in grid map to 2 fps changing settings with vr on.

forget disabling and re-enabling your vr, that will either crash the game or make it run so poorly your whole pc might crash.

at that point of settings being the lowest, the tree infront of the car is a bushy 6 pixel mess. and im still getting max 12 fps on industrial

I don't blame them for not working on some guide/tutorial, since I'd rather them work on hotfixes

afaik fixes/issues:
(and again, below is only afaik)

vr has a bug with vram where it never removes un needed vram. so loading in vr, then loading in 3 differnt maps, if each map is 4gb vram, then you will already have 12gb vram being actively used
vram gets used up heavily by loading different maps, vehicles, having high settings, and by simply changing settings.
to get around this, go with lowest graphics you can handle, and if you want to change map etc try to restart beamng.
going overboard on vram causes freezes or massive performance hits

you should load up beamng, then load up vr, then load up a map

there is some issue where using wireless vr headsets have a massive performance hit - try cabled
vulkan is kinda buggy and iffy - like some dude is saying before .30 vulkan did 120fps on ultra, but post .30 vulkan does 30fps on ultra

(another reminder everything is only afaik)

thanks, this clears up and answers lot of issues i had.

i figured that disabling shadows in debug mode allows me to play the game on normal, launching big big maps. so the shadows are the culprit, they also like to glitch out. which is already a known bug. so, i guess we have to wait for lighting overhaul... or something

[Seba]

also just now, i figured that ambient occlusion is the culprit for glitching shadows, it just doesnt work with beamng for some reason

and you dont need vulcan to run the game in, it actually runs better in normal mode. at least to me : )
