What does 1% low FPS mean in Rust benchmarks?

The 1% low FPS measures the worst-case frame rate during gameplay, the FPS that 99% of frames exceed. In this benchmark, the average is 84 FPS and the 1% low is 56 FPS. A small gap between average and 1% low means consistent frame delivery with minimal stuttering.

Tips & Tricks4

GPU Temp Sensor

GPU temperature reported 1°C, this is a sensor reading failure. Temperature data for this session is unreliable. Try updating GPU drivers or check if monitoring software is conflicting.

Moderate 1% Lows

1% low FPS drops to 56 FPS, frame drops below 180Hz cause visible stuttering. Ryzen 5 5500 usage at 100% is the bottleneck.

Critical CPU Usage

CPU usage hit 100% while GPU sat at 45%. Your GPU has headroom, upgrade the Ryzen 5 5500 or close background apps to increase FPS.

Critical RAM Usage

RAM usage peaked at 97% of 16 GB. Close background apps to free up memory, or upgrade to more RAM.
