I finally found a fix to this thanks to another user because gaming on linux was unplayable to me because it took forever for the shaders to process everytime i started a game.

Go to

.local/share/steam  (Here you should see other folders like appcache, bin, clientui, compatibilitytools.d, config etc

If you use a flatpak version

go to .var/app/com.valvesoftware.Steam/data/Steam

> Create a file called steam_dev.cfg
> Open the file with any text editor and add

unShaderBackgroundProcessingThreads X

where X is the number of threads for your cpu if you have hyperthreading
For example if you are using i9,13900k your threads is 32.
If you are using Ryzen 5 4600 you have 12 threads.
