Sub 40% GPU usage despite low framerate and sub 25% CPU usage in steamVR (2080ti, r5 3600, rift S)

Since i've received my Rift S a few months ago, i've been avoiding steamVR because of really wonky performance.

My specs are:
R5 3600
2080ti (this model has 11gb of vram)
16gb of 3200mhz ram
Rift S

GPU frametimes will spike nonstop while the GPU usage is permanently stuck under 40%. This is while my CPU frametime stays below 5ms consistently. This results in an average framerate of approx 40-45fps in steamVR, occasionally spiking to the high 60's. I'm measuring this through SteamVR's advanced performance graphs, and confirming via MSI afterburner. Ram and Vram usage and are always sub 85%, but amount used depends on the title. At this level of performance, there are constant graphical smeary almost-watery artifacts, which i assume are a result of reprojection to compensate for my subpar performance.

Approximately one out of ten to fifteen launches of SteamVR, performance will be great, GPU usage will hit about 60%. This will continue for about an hour or two, when performance will decide to degrade as my GPU usage over time reduces its usage to under 40% and park itself there.

This doesn't happen in any non-VR applications, and I can't find anyone else with similar symptoms online.

With the release of boneworks, this sort of breaks the physics engine in that game, making it near unplayable compared to two instances in which i've had really good performance for about an hour or two.

I have not noticed any similar symptoms when SteamVR is disabled.

What can I do to kick my GPU's ass into submission? Lazy prick.

    There is nothing you can, Ever since Oculus released the 12.0 update it has fundamentally messed up most VR games, In most games I never see the CPU or GPU go above 50%, its as if there is some sort of artificial limit there keeping the hardware capped at 50% and lower, It makes no sense.

    Yup, its not your PC and don't let anyone tell you it is. Oculus fucked up. Bad. I've posted in a bunch of topics about this, but I'll keep doing it. I don't appreciate having a 500 dollar paperweight because of their refusal to rollback an update that they messed up. Keep bumping this shit to the first page.
