This is fixed with amdvlk-pro 21.10.1247438.
I also can't reproduce anymore with amdvlk-open v-2021.Q2.1 in Mirror's Edge. So it seems this was fixed either by recent firmware updates in linux-firmware git-master or by bios update version 1.70 for my mainboard.
Whoops, I tested the wrong scene in Mirror's Edge. Performance is still bad with amdvlk-open v-2021.Q2.1 when I test the scene seen above in the screenshot, despite of updated bios and firmware. Whereas it's really fixed with amdvlk-pro 21.10 in both Strange Brigade and Mirror's Edge, so it seems it really all comes down to the driver.
But now performance in Mirror's Edge definitely is fixed also with amdvlk-open, thanks to v-2021.Q2.2. :)

Mirror's Edge (D3D9 -> Vulkan DXVK, recent Proton) 1st scene during tutorial, Above 4G Decoding disabled, amdvlk-open v-2021.Q2.1:

With RADV, enabled Above 4G Decoding doesn't hurt performance.
