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 71 FPS and the 1% low is 24 FPS. A small gap between average and 1% low means consistent frame delivery with minimal stuttering.

Tips & Tricks6

Low 1% Lows

1% low FPS drops to 24 FPS, frame drops below 144Hz cause visible stuttering. i5-13420H usage at 85% is the bottleneck.

High CPU Usage

CPU usage hit 85% while GPU sat at 47%. Your GPU has headroom, close background apps or lower settings to increase FPS.

Hot GPU Temp

GPU peaked at 85°C, thermal throttling detected. Use a cooling pad, clean air vents, or limit FPS to reduce heat.

Critical CPU Temp

CPU peaked at 93°C, thermal throttling detected. Use a cooling pad, clean air vents, or undervolt the CPU.

Critical RAM Usage

RAM usage peaked at 99% of 16 GB. Close background apps to free up memory, or upgrade to more RAM.

FPS Limit 144

FPS was capped to 144 but it was not reached. Remove the FPS limit in Rust settings for reliable data.

Answers About Your Benchmark

speedHow many FPS does RTX 4050 Laptop GPU get in Rust at 1080p?expand_more

RTX 4050 Laptop GPU delivers 71 FPS average in Rust at 1080p. 1% lows hit 24 FPS. Some frame drops during demanding scenes.

compressIs i5-13420H bottlenecking RTX 4050 Laptop GPU in Rust?expand_more

Yes, i5-13420H shows signs of a CPU bottleneck at 85% usage while RTX 4050 Laptop GPU sits at 47%. A faster processor would unlock higher FPS.

memoryIs 16GB RAM enough for Rust?expand_more

Rust used 94% of 16GB RAM. Running tight, upgrading to 32GB is recommended if you multitask.

thermostatWhat are normal GPU and CPU temperatures while gaming?expand_more

The RTX 4050 Laptop GPU reached 80°C and the i5-13420H reached 88°C. On the warm side, check your case airflow and thermal paste.

trending_downWhat does 1% low FPS mean?expand_more

The lowest FPS drops, your lag spikes. Here it's 24 FPS vs 71 FPS average. The gap suggests noticeable frame drops during intense scenes.

boltHow do I get more FPS in Rust?expand_more

Your CPU is the limiting factor, lower CPU-heavy settings like draw distance, physics, and NPC density. Your temperatures are high, clean your fans, check case airflow, or repaste your cooler. Thermal throttling kills FPS. Check the Tips & Tricks section above for specific fixes based on your benchmark data, including background apps, driver issues, and hardware settings.
