What it does
Forces Windows to use the High Precision Event Timer via a boot flag.
The honest verdict
Refused. On modern Windows this almost always RAISES latency and causes stutter — the OS already picks the best timer. A classic forum tweak that backfires.
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.
