A buddy of mine has a 1060, some Ryzen5, 16Gb RAM and a Rift.
He installed DCSW and invited me over (because he has no clue about flight sims and to show me VR).
Sure you play with low details, but yeah, I could fly the Su25t and the TF-51 in VR just fine, even over Tbilisi.
We played Skyrim VR and used Google Earth VR and it worked well. Much better than I thought.
VRAM is to the GPU what RAM is to the CPU and during games you should find it wont be using any shared memory across RAM because the exchange is too slow. I have not seen DCS try and go to RAM when the VRAM is full myself. My previous card was 3GB and topped out on low settings.
Normandy ~7GB
Nevada ~5.5GB
Caucusus ~5.5GB
Multiplayer any 7+GB
(only 1080p btw)
To add it also doesn’t matter what it is using now but future game enhancements generally pile on the resource requirements. I know Vulcan is the new messiah on the horizon but generally these things never turn out as good as the hype.
That’s weird. I have the textures on high and it runs OK (not great but OK) unless there are many objects in the mission. Sure, a lag now and then and sometimes I can see it load new textures a bit slowly.
My card is a 970M so it has 3GB I think and shares another 3 with the system.
