Huh. So apparently SteamVR for Windows Mixed Reality crashes when you turn on the controllers... if you're running in a VM with a certain CPU configuration? This sounds like one bizarre heck of a bug.

I'm running it on my TR box with GPU passthrough, and I ended up opening a ticket with support because it just looked like a random crash unrelated to the VM. But then on a hunch I changed my CPU topology and RAM and that... fixed it?

I haven't bisected it yet, but I went from 1s8c16t 32G unpinned to 1s8c8t 16G properly NUMA pinned and cores pinned to 8 physical cores on the die the GPU is attached to. But, like, all of this should be a performance thing only?

Or is there some nontransparent stuff about hyperthreads that can crash software when they aren't where the OS thinks they should be?

Anyway, >400 combo on Beat Saber says this VR gaming in a VM idea works perfectly fine, once it works.

I wouldn't be surprised if unpinned exposes GPU driver bugs.. but then I don't really know how all that NUMA stuff works anyway

Yeah but it's crashing in the *controller* code of all places?

Wild guess, but maybe you just hit the threshold to trigger a tight race condition?

It's completely consistent though... Crashes if I boot it with controllers turned on, or after I turn them on if I boot it with them off. seems unlikely...
