A CPU bottleneck occurs when your processor cannot keep up with your graphics card (GPU), leading to stuttering, inconsistent frame rates, and underutilized hardware. This detailed guide covers how to identify, resolve, and optimize your CPU for peak gaming performance. 1. Identifying a CPU Bottleneck
Frequent stutters or "micro-stuttering" (low 1% frame lows) are classic signs that the CPU is struggling to handle game logic or background tasks. 2. Optimizing Windows for CPU Performance
Lower your game's resolution (e.g., from 1080p to 720p). If your FPS does not increase, your CPU is at its limit and cannot process more frames.
Use overlays like MSI Afterburner or HWInfo64 while gaming.
Before applying fixes, you must confirm the CPU is the limiting factor.
