100 GB shadercache folder

[paolobettelini]

Hello, I hope this is the right place for this issue since I'm not 100% the problem is on your part.

So I'm running an Arch Linux system under Wayland. Installed wine/proton with Steam and activated the background shader processing.

I noticed that my ~/.local/share/Steam/steamapps/shadercache folder has grown over the last few weeks to ~100 GB.
The only game I'm running is Warframe, which is less than 50 GB.
Upon starting the game it does the usual "processing vulkan shaders" which I reckon takes a full hour with 100% usage of each of my CPUs, thus I activated the background shader processing feature which sometimes starts this software and uses 50% of my CPU.

Is this size expected behavior? It's seems quite unlikely to me that the game needs to cache (more than double its full size) of vulkan shaders.

Thank you for your time
