Tips & Tricks5

Good 1% Lows

1% low FPS drops to 101 FPS, frame drops below 165Hz cause visible stuttering. GPU peaked at 88°C and CPU at 100°C, thermal throttling detected.

Low Utilization

GPU at 59% and CPU at 37%, neither is fully loaded, yet 1% low FPS drops below your 165Hz refresh rate.

Hot GPU Temp

GPU peaked at 88°C, thermal throttling detected. Clean dust filters, GPU heatsink, or improve case airflow.

Critical CPU Temp

CPU peaked at 100°C, thermal throttling detected. Reapply thermal paste, clean dust, or improve case airflow.

FPS Limit 360
