Shader cache processing trigger in Linux?

[Bebef]

Hi everyone!

Can someone tell me what the trigger to processing the shader cache is? I'm under the impression that every game wants to process the shader cache every single time I launch it. I don't think that this is the normal behaviour, so I'm looking for things that cause the shader cache to be processed.

Thanks

It's compiling the Vulkan shaders. It's normal behaviour on Linux.

By compiling the shaders before running the game you avoid having to wait for the shaders to compile while you are playing. Doing so avoids stutter and lag on your first playthrough of the game.

It is triggered on the first launch and whenever the graphics drivers are updated/changed.

In the Steam settings you can enable a setting to make it automatically compile shaders in the background, it will do this on only a single thread so you shouldn't notice it is doing this on any modern machine.

Okay, maybe I should update graphics drivers less often ;)

Only update when you're experiencing problems, if there certain features needed on newer games, or update was aim toward fixing performance on specific games you're trying to play.

This is Linux, this stuff is all updated at once. All the software is installed from central software repositories. If you look for updates all software installed through the package manager is updated at once.

And that is the thing, you always want the latest drivers on Linux since it will have a big impact on performance and game compatibility. Especially when running AMD graphics.

If I look for updates now I get this

Do you want to continue? [Y/n]

Linux5.8 is going to be updated. The AMD and Intel GPU display drivers are a part of the Linux kernel. This will likely not trigger the shader recompilation in this case, it's more dependent on MESA. But I think the idea is clear.
