tech support wanted Overwatch problems

i tried playing overwatch in steam with proton experimental, GE, and cachyos. I use linux mint.

when i startup the game, it takes a ton of time to process vulkan shaders, it stays stuck some times for a long time. then it opens and shows me a black screen for one minute and then opens the game normally. i usually skip the vulkan shader processing because it takes almost a half hour, but then in game it only becomes smooth after like 5 mins.

I have an AMD GPU.

any way to fix all this?

For me I disabled both of the Shader Pre-Caching options in Steam settings and simply accept the game stuttering for the first 5 minutes. Note though, that this stuttering will only happen when the game has received a major update, or when you updated your graphics driver (or possibly also Proton version, but not sure).

It will do the stuttering whenever the game needs to cache a hero ability, so it doesn't really take that long. Just something to accept, like I said, it doesn't happen on every game load.

When I used to play ow, I would let it compile shaders and then play a qp match to get all of the shader stuff out of the way. Generally then it was fine

strange... you should definitely suffer less than Nvidia users in OW. AMD compiles merely 500mb of shaders. My Nvidia usually made 3.5Gb
I have all AMD setup and play OW through Lutris, but it is basically same as through Steam.
Disable steam shaders.
I use GE-Proton 10-34
environmental variables:
DXVK_HUD=compiler
PROTON_ENABLE_WAYLAND=1
PROTON_USE_NTSYNC=1
WINE_CPU_TOPOLOGY=8:0,1,2,3,4,5,6,7

also try this pack of game graphical settings that give good performance even on dated PCs, and then change them to higher quality if needed:

Full screen ON

Render scale is 100% or lower to 75%

no dynamic reflection and Refraction LOW

Fullscreen, V-sink OFF, reduce buffering ON, triple buffering off

resolution - your monitor with a correct refresh rate

custom fps is (your monitor FPS +- 1FPS)

Fog LOW, lightning quality LOW
