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 66 FPS and the 1% low is 21 FPS. A small gap between average and 1% low means consistent frame delivery with minimal stuttering.

Tips & Tricks8

CPU Temp Sensor

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

Low 1% Lows

1% low FPS drops to 21 FPS, frame drops below 144Hz cause visible stuttering. GTX 1660 SUPER usage at 65% is the bottleneck.

Moderate GPU Usage

GPU usage hit 65% while CPU sat at 50%. Your GTX 1660 SUPER is the bottleneck, upgrade, lower graphics settings or resolution to increase FPS.

Critical RAM Usage

RAM usage peaked at 98% of 16 GB. Close background apps to free up memory, or upgrade to more RAM.

Critical VRAM Usage

GPU VRAM usage averaged 5.5 of 6 GB (peaked at 92%). Lower graphics settings or resolution to avoid stutters from VRAM pressure.

Outdated GPU Driver

GPU driver is 7 months old (version 581.42, 2025-09-22). Update to the latest driver for bug fixes, game optimizations, and potential FPS improvements.

FPS Limit 145

FPS was capped to 145 but it was not reached. Remove the FPS limit in Rust settings for reliable data.

Browser Running

A browser used 15% CPU and 0% GPU during the benchmark. Close all browser windows for cleaner results.
