Classify the problem as audio stutter, frame spike, input latency, control loss, or low frame rate, then test osu! with the default skin, Optimal frame limiter, exclusive fullscreen, overlays closed, and official current drivers.
Determine whether audio rewinds, frames spike, input is delayed, controls stop responding, or frame rate stays low. Record when it happens and whether it repeats at a fixed interval.
2
Return to a safe baseline
Switch to the default skin, set the frame limiter to Optimal instead of Unlimited, and use exclusive fullscreen. Test the same beatmap after each change.
3
Close overlays and heavy tasks
Close Discord, Steam, NVIDIA overlays and unneeded applications. Use Task Manager to watch CPU usage while reproducing the spike.
4
Compare graphics processors
On a hybrid-graphics PC, use Windows Graphics settings to test osu! on Power Saving and High Performance. The osu! wiki notes the integrated GPU can sometimes be more consistent.
5
Check drivers
Use official current GPU and input-device drivers. If the problem began immediately after an update, test the vendor-supported rollback path.
6
Branch for audio stutter
Test another audio device and enable Audio compatibility mode. Do not change unrelated graphics settings if only audio rewinds or glitches.
7
Verify and report
Run the same beatmap in autoplay after a restart. If the issue remains, capture the lag type, frequency, frame-time graph, hardware, driver version, skin, and frame limiter for osu! support.

If it does not work
If Ctrl+F11 shows white spikes, compare the timing with Task Manager CPU activity and close the matching background process before changing osu! graphics settings.
If only input is delayed, compare another input device and official drivers; if only audio stutters, test the audio-device and compatibility-mode branch instead.
