CS2 Broken brightness slider using Vulkan launched from steam

[kristiker]

Steps for reproducing this issue:

1. AMD GPU, 23.9.1, -vulkan, Windows
2. Launch from steam, brightness slider doesn't work.
3. Launch executable, brightness slider works.

After 28 September update, screen also capped to 60hz. sys_info reports 144hz. Update: 29 September update fixed 60hz lock.

same issue occurs in the linux build in both xorg and wayland on fedora linux, with and without -vulkan cmd arg (although im not sure it does anything on linux)

had this issue since launch

another thing im noticing that might be related, the command r_fullscreen_gamma has zero effect, so the game may not actually be running in exclusive fullscreen

Is there a difference on linux between launching the executable and pressing play on steam?

[jali-peno]

launching the executable directly (both the actual binary and the shell script steam uses to start the game) wont work.

launching the executable file directly results in a missing file error, something to do with panorama, and launching the script gives an error that the game can only be run through steam
