How Does PC Bottlenecking Actually Work?
1. CPU Bottleneck (Draw Calls)
When your GPU is capable of generating 200 frames per second but your CPU can only process instructions and physics calculations for 120 frames, the graphics card sits idle waiting. This is especially prevalent at 1080p competitive settings.
2. Resolution Scaling (1080p vs 4K)
Increasing resolution from 1080p to 1440p and 4K shifts 90% of the computation load onto the GPU VRAM and raster cores. A pairing with 20% CPU bottleneck at 1080p often exhibits 0% bottleneck at 4K.
3. GPU Bottleneck is Normal
Having a GPU bottleneck is generally ideal for gaming. It indicates that you are getting 100% of the graphics performance you paid for, with no frame pacing stutters caused by CPU thread saturation.
