Why Is My GPU Bottlenecking My CPU? (Understanding PC Bottlenecks)
Learn how CPU and GPU bottlenecks work, why 100% GPU usage is actually ideal for gaming, and how to identify true hardware limitations.
The Myth of the 0% Bottleneck
Every single computer in existence has a bottleneck. Without one, your computer would generate infinite frames per second! In PC gaming, the bottleneck simply refers to whichever component reaches 100% utilization first, capping overall performance.
GPU Bottleneck vs CPU Bottleneck
GPU Bottleneck (Desired): When your GPU runs at 95–99% utilization while your CPU sits comfortably at 30–60%. This is the ideal state for gaming, ensuring you are extracting maximum performance from your graphics card.
CPU Bottleneck (Undesired): When your GPU utilization sits at 50–70% because the CPU cannot prepare draw calls fast enough. This leads to erratic frametime spikes and choppy stuttering.
