Near zero GPU utilization in VR

I have a 5800X3D, 4070 Ti, 32 GB of RAM and a Reverb G2. Nothing’s overclocked.

My GPU is working at about 40 % in flatscreen mode (1080p). Kind of low in comparison to 2020’s 60 % or so, but not horrible. However, when I switch to VR mode, my numbers go down to 1-3 %. The GPU seems to barely do anything based on the readings. The only way that I’ve found to increase the GPU utilization is to enable motion reprojection in OpenXR Tools, which increases it to a whopping 12 %. This is about as high as it gets.

In 2020 switching to VR increases GPU utilization instead of decreasing it. It goes from the usual 60 % or so to maybe 70 %. If needed, it can sometimes use 95 %.

Performance itself in 2024 is not quite as bad as I would think based on the readings. It tends to look more blurry than 2020 and airports such as KLAX and KJFK are unplayable due to horrible stuttering. Other than that, I’m getting a fairly smooth 30-45 FPS (plus reprojection) experience despite the low GPU utilization. This is of course still not acceptable, because I like big airports in big cities.

Is anyone else experiencing the same?

DX-12 uses Graphics_1 to measure not DX. You have to change that in Task Manager.

I’d recommend this thread. DLSS tweaks, openXR toolkit and performance in VR - User Support Hub / Virtual Reality (VR) - Microsoft Flight Simulator Forums

VR in 2024 can look better and perform better than in 2020 (although the same might work in 2020). It just takes a little extra work that I hope Asobo soon adds to the sim as default.

From what I’ve been reading too, 64 GB of ram seems to help.

Hey Poppy, I have the same issue of this guy that you replied to.
I do not understand what do you mean with your solution: can you please explain me? “DX-12 uses Graphics_1”?

I am running in very low GPU usage when in VR, and the sim in unusable.

DX-12 needs Hardware-accelerated GPU scheduling turned on for GPU usage to properly show in Task Manager performance section.

Thank you. Yes, it is all on.
I cannot figure out why MSFS2024 at some point gets very high CPU and low GPU making the game unusable.
This happens mainly in VR. The PC runs well. I can do DCS in VR for hours with no issues
