The Home of FlyInside Flight Simulator FFS FSX P3D and X-PLANE Message Board

Hello

I just checked back, 600MB textures in X-plane translate to approximatly 4GB VRAM usage with FI at 2880 resolution.

With mine set to "high" and running in 2D (non vr) as a test (1080, rather than 5760x1080)..
I see 928MB loaded in XP.. while the Memory used is 3452..

Then i fire up VR..
I see 740mb loaded in XP (high again).. while the memory used is 6386 at 3840 FI res

I then increased textures to maximum and
I see 1804 mb loaded in XP.. while the memory used is 7285 at 3840 FI res
***with this mode i'm seeing 54% gpu use and only 13% cpu for x-plane.exe (this doesnt seem right, at least on the cpu, why so low).




If i run 1080 mode in 2D and with 2SSA+FXAA and reflections on medium instead of low and shadows on scenery checked.... and set to maximum the textures.. i see 4779MB used in gpuz and 1905MB in XP.. meanwhile GPU is at 39% and cpu is up to 30%

I dont know, same here, the closer I get to my VRAM limit the less cpu and gpu usage I have.
Maybe just not enough free memory to manipulate the data, seems like we are starving the gpu and cpu.

Hello, does that mean that it is impossible to use xplane and flyinside with my gtx970? It has 4gb memory. Does it run xplane or p3d in virtual reality anyway?
Tnx!

No it is not impossible, you will probably need to use lower resolution and less antialiasing, but it still will be exciting.
I used to have a 780ti with 3GB and it worked, I think this thread is more about maxing out.

Updated to Pb8 from pb6, i find about 5-6 fps increase.

I tried to set to 4xAA in Sim + 3840, still drops to like 67 on atw and 27 for sim rate.. too low.. vram at about 7600 and gpu 70-90%.. tried 2x in sim with 8x FI and frame rate is around 29 fps (NYCX DD clear weather) and with 2x in sim and 4x about 33 fps, whereas with AA off in sim and 8x in FI before i was 40 fps with pb6 (and 46 or so with pb8).. so 2x isnt bad though i'm not sure i see much improvement in shimmering even with 2x enabled.

I do think that there is far less shimmering with 2x AA turned on in sim, either way. 4x is still too much for this video card though.

Its really a shame there is no way to brighten up the cockpit/world with HDR set to off.. as when its off, the shimmering is greatly reduced. Perhaps something like Maxxfx would help

I decided to give it a shot..

Unfortunately, MaxxFx had NO effect on XP 11 in the goggles (but the on screen window it did).
