Update Windows and the graphics driver, assign the game to the high-performance GPU, test Windows 11 windowed-game optimizations, and reduce measured bottlenecks. Registry cleaners and priority hacks are unnecessary.
Install current Windows quality updates, then review Windows Update > Advanced options > Optional updates for a relevant display driver. Prefer a newer driver offered by the GPU or computer manufacturer.
Open Settings > System > Power & battery > Power mode and choose Best performance while plugged in when the extra heat, noise, and power use are acceptable.
Close only apps visibly consuming substantial resources, then lower demanding in-game settings one at a time and rerun the same FPS test.

If it does not work
If all games slow after a driver update, use the GPU manufacturer's supported rollback or clean-install guidance and record both driver versions.
If one game alone is affected, check that game's official patch notes and requirements; overheating or hardware limits need a hardware-specific diagnosis.
