Fixing screen flicker issues for PCCOOLER RT620P in The Witcher Remake
This is a classic case of thermal trigger drift under high-frequency ray tracing loads. Running 22H2 with Driver 545.0, based on Report Log-8821, the fan hit sampling conflicts at its 1850 RPM peak. Skip the driver reboot; it is useless. I navigated to the System Control Panel and used a dependency repair suite to perform a full depth scan, purging 1.6 GB - 2.7 GB of redundant architectural cache. Checking via HWinfo, the fan speed oscillation was crushed into a tiny ±95 RPM range, and the heartbreaking flickers vanished instantly, leaving the visuals roca steady. Warning: if your BIOS has aggressive auto-voltage scaling enabled, this DLL fix can cause sensor read latency during the first 30 seconds after a cold boot, meaning the solution comes with a minor temporary trade-off.
