Why is STALKER 2 compiling shaders every time?

Tired of the STALKER 2 compiling shaders message? You’ll have experienced this every single time you launch the game on PC while you wait for the progress bar to fill. It’s pretty irritating considering there’s no way to get past it. So, what exactly is it?

The short answer is that when STALKER 2 is compiling shaders, it's reworking a bunch of graphical tricks and turning them into something your PC can use. While you might be used to seeing this message happen once, in STALKER 2, it’s a repetitive task. Shaders are basically fancy maths that moves and changes pixels on the screen to manipulate different visual effects, and covers everything from textures, lighting, and shadows that you’ll experience throughout the game. It's an extra layer on top of basic shapes and lights that makes things a whole lot look better.

However, to ensure STALKER 2 runs smoothly, shaders need to be converted into as simple a form as possible, and specifically to suit your set up - different PC components, GPUs, drivers and so on mean a unique compiling process. It can take an annoying amount of time, so games often compile shaders right at the start of the game. If they tried to do it as and when, it’d cause stuttering and slow down the game, which is arguably even more annoying.
