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 73 FPS and the 1% low is 43 FPS. A small gap between average and 1% low means consistent frame delivery with minimal stuttering.

Tips & Tricks4

Moderate 1% Lows

1% low FPS drops to 43 FPS, frame drops below 165Hz cause visible stuttering. i3-14100F usage at 72% is the bottleneck.

Moderate CPU Usage

CPU usage hit 72% while GPU sat at 31%. Your GPU has headroom, upgrade the i3-14100F or close background apps to increase FPS.

High RAM Usage

RAM usage peaked at 89% of 16 GB. Close background apps to free up memory, or upgrade to more RAM.

Single Channel RAM

RAM is running in single channel mode, halving memory bandwidth. Install a second stick to enable dual channel for a significant FPS boost, especially in CPU-limited games.
