Most Vulkan games don't appear to work with latest Proton or GE-Proton

I installed ChimeraOS this afternoon on this computer: https://a.co/d/7GpHv4y

The install was relatively smooth, but one bit of weirdness is that that I cannot get most Windows games even launching. This is from the main big picture mode, not the desktop variants.

With the default Proton install, I tried:

Chronicles of Riddick Assault on Dark Athena
Bionic Commando
Super Motherload.

All of which which will spin for awhile, open the Steam spinner, and then immediately crash, without even an error.

The first ones I thought might have some issues with DRM, so I thought there's a potential issue with that, but I know Super Motherload worked fine on CrossOver on my Mac only two weeks ago.

I then tried the latest GE-Proton (9-5), with no difference in results.

I was eventually able to get Super Motherload working by changing my Proton version to 4-11, but that didn't fix Riddick or Bionic Commando.

If I could see a log or something that would really be helpful, but I'm not sure how to find any kind of log dump. Any ideas on how to fix it? I'm happy to provide more information.
