"Vulkan Shader Processing" is a Steam feature that is specifically used in Steam Play/Proton, a solution that allows you to run video games created for Windows on Linux.
Обробка шейдерів Vulkan
When you first run the game, Steam analyzes the shaders (programs that perform calculations to render 3D graphics) of the game and converts them into a format that is optimized for use with the Vulkan GUI library. This process may take a little (sometimes not a little, depending on the computer) time, but it is performed only once for each game.
Vulkan shader processing can improve game performance, especially when using Steam Play/Proton to run Windows games on Linux, as Vulkan often offers better performance on Linux than DirectX, which is often used in Windows games.
It is also worth noting that this feature requires your graphics card and drivers to support Vulkan.
Can Vulkan shader processing be skipped?
You may skip this process of handling Vulkan shaders on Steam, but this can affect the performance of the games.
It is important to understand that shaders are a key part of 3D graphics rendering, and optimizing them can greatly improve game performance. If you choose to skip this process, shaders will compile "on the fly" during the game, which can lead to long downloads, game breaks, or even reduced overall performance, FPS, and more.

But if you still need to skip shader processing, you can do so by opening the Steam settings, going to the "Downloads" section, and unchecking the "Shader Pre-caching" item. Note that this can reduce the performance of games.
Or you can click on the "Skip" button when starting the game.
