January 4, 20224 yr DX11 because of VR. On another note, I don't have any complaints about MSFS's performance it runs as smooth as butter for me on really high settings even in VR. The smoothest simming I've ever experienced honestly and every update seems to get better as far as performance headroom, and I'm able to increase graphic sliders even further with each SU. I haven't had to worry about OOMs, stutters ,FPS and CTDs with this new sim and it's really great to be able to enjoy these addon combinations with peace of mind!

January 4, 20224 yr DX12 I am experiencing many more CTD events in VR (OpenXR/WMR no SteamVR) than with DX11 - but it is still early days to see if DX12 is the problem. I turned on DX12 shortly after Steam unexpectly upgraded my Sim to 1.21.18.0 (public beta). My VR flights are showing much better frame rates (+20% or more) with the public beta/DX12/NIS mod but cannot say which is the cause of the increase. All I know is that I am pleased.

I wonder how many 3rd Party add-ons made for DX11 could be causing CTD's in DX12? Edited January 4, 20224 yr by Kilo60 Chris Camp
January 4, 20224 yr I got worse performance with dx12 with my old 1080 monitor, but when I got a new 1440 monitor I was having big problems and obly getting half the framerates I was with the 1080 monitor. As a last resort, I switched to dx12 and my framerates doubled. This is a complete mystery to me as I am basically using the same settings in both msfs and nvidia. Whilst I am getting decent framerates now, overall performance is jittery as hell, with stutters and pauses all over the place both with a full community folder and an empty one. I have a feeling that the lack of vram on the rtx3070 might be playing a part in this. Previously I was CPU limited but at 1440 I am GPU limited.

January 5, 20224 yr DX11 here. I understood that DX12 is only a layer still and no real DX12 functions are enabled yet? I tried DX12 but got worse performance with the same settings in the sim so I switched back.
