The summary CPU usage says nothing about the CPU usage 🤓
You have to look at the cores that are limiting, in fpsVR there are bars for the usage of the cores.
It's also possible to analyze with Afterburner.
Thanks, will try that out later!
I tested this further tonight with MSI Afterburner, showing all 16 CPU Cores in the hardware monitor, but none of them went anywhere near 100%. The highest through the stage was 64% on any core at any point in time, and yet, I'm constantly CPU bound. Doesn't add up, does it?
Can you also test this by adding -dx11 to steam launch command line?
Dx12 doesn't show correct GPU usage in task manager for example, I know that much
I've changed my configuration quite significantly since that post. Went from running OpenComposite (OpenXR), and some tweaks in the OpenXR Toolkit Companion App, to now just running via SteamVR with OpenXR Runtime. I'm no longer CPU limited, at least according to fpsVR, which shows I'm consistently at 90fps now, but performance between the two runtimes feels very similar, with the stutter you mentioned in your video present regardless. Anyway, I'm at least running some stages now, so I'm reluctant to change everything back at the moment, just for the sake of testing. I've resigned myself to the fact that there's nothing I can do to get this to run well in VR, and it has to be a fix by Codemasters.
