While it is not ideal, it should be working in the next release of Proton (4.11-3) provided that Valve includes these two patches:
https://github.com/doitsujin/dxvk/commit/4cce07ccd9bec3f338c6eb36130730372191c02b
https://github.com/doitsujin/dxvk/commit/1999ca9dd4aa24e5bbbb8f0aab045b4eeb4f7f35
See the DXVK issue:
The fixes for this did not make it into Proton 4.11-3. I am hopeful that they will go into Proton 4.11-4.
I have not tested 4.11-4 but it works in 4.11-5.
It was fixed in 4.11-4. Unfortunately, some testing with 4.11-5 on a Ryzen 5 3400G that I am setting up for someone else found that it crashes there, so more is probably needed here. If it were not for that, this could probably be whitelisted and closed.
works perfect on Proton 4.11-8 with Intel + Nvidia
Also works fine on Proton 4.11-8 with AMD + Nvidia
(Although Valve Index tester is broken, but I don't think this is the right thread or possibly even repo.)
It's also no longer available on the steam store in the reported app. Closing this old issue.

Your system information
Please describe your issue in as much detail as possible:
SteamVR Performance Test is not available for Linux/SteamOS.

This makes it more difficult to determine if I should get VR on Linux..
