What it means
Before the GPU can draw an effect, the little programs that describe it (shaders) have to be compiled for your exact hardware. Doing that mid-game is a leading cause of stutter.
More detail
When a game shows a "compiling shaders" screen, let it finish — it's doing the work up front so it doesn't hitch later. Skipping it only moves the stutter into your gameplay. Letting the driver keep a big shader cache on disk helps too, so the work isn't repeated every launch. This is a top suspect in UE5 games.
