Disable CPU security mitigations (Spectre/Meltdown)
Also searched as: spectre · meltdown · mitigations off · inspectre
What it does
Turns off side-channel attack protections for a small CPU uplift.
The honest verdict
For GAMING the gain is ~0–4% (the big numbers are servers); the cost is re-opening known, documented exploit classes. The FPS rounding error isn't worth it.
How Compy treats it
It's on Compy's refuse list. Compy will never apply this tweak — and if a guide already talked you into it, reversibility is the whole point of the app.
The Compy Blackbook holds 174 graded entries like this one, judged against your hardware — and every change it does make is reversible, with the receipt to prove it.
