Tips & Tricks4

Moderate 1% Lows

1% low FPS drops to 41 FPS, frame drops below 60Hz cause visible stuttering.

Low Utilization

GPU at 40% and CPU at 43%, neither is fully loaded, yet 1% low FPS drops below your 60Hz refresh rate.

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.

Outdated GPU Driver

GPU driver is 11 months old (version 31.0.21923.11000, 2025-07-01). Update to the latest driver for bug fixes, game optimizations, and potential FPS improvements.
