Shader cache size (unlimited / 10 GB)

What it does
Lets the driver keep more compiled shaders on disk.
The honest verdict
Graded real. Cheap and real, but for a specific kind of stutter: a bigger cache lets the driver reuse compiled shaders instead of rebuilding them after a driver update or a cache wipe — it does not stop a game's first-run shader compile (that is the engine's job, which is why letting games finish their shader pre-compile screens matters more). The size knob is mainly an NVIDIA thing; AMD's cache has no size cap. …
Where it genuinely fits a rig, Compy can recommend it — applied with a snapshot first and a one-click rollback after, like every change it makes.
The full graded entry
The rest of this write-up — the specifics behind the grade — ships inside the app. The Blackbook publishes its verdicts here — the full write-ups stay in the book, on your rig, next to your own measurements.
The Compy Blackbook holds 191 graded entries like this one, judged against your hardware — and every change it does make is reversible, with the receipt to prove it.
