Can you try with non-Flatpak Steam? Like Steam (Runtime)

The result is exactly the same
I tried it with Cyberpunk 2077 now (which can't run on proton 5). It looks like I can run the game with VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.i686.json:/usr/share/vulkan/icd.d/radeon_icd.x86_64.json and it will run on integrated gpu, at least. even if I use variables from prime-run, it won't run on nvidia gpu. Changing icd filenames to nvidia_icd.json (provied by nvidia-utils package) makes the game crash on start.
I have a laptop with amd processor (and integrated gpu) and nvidia gpu. To switch between the two I use optimus-manager. However, the update in drivers 470 made some changes so that it's possible to run stuff on nvidia gpu while in "integrated" mode, where X11 session uses integrated gpu and nvidia gpu stays powered down until needed. This is similar to how things work in windows.
So I tried to run The Witcher 3 and realized I couldn't (here is output of steam run in terminal). However, I can run it if I switch to "Nvidia" mode in optimus-manager (where X11 session is ran on Nvidia gpu), or if I use proton 5.0. Looks like sort of a regression to me.
