FAQ
- What is a PC bottleneck?
- A bottleneck occurs when one hardware component (either CPU or GPU) limits the performance of the other, preventing your system from utilizing its full computing potential during gaming.
- Why does the bottleneck change with resolution?
- At lower resolutions like 1080p, the CPU is highly stressed to handle game logic and feed frames to the GPU. At higher resolutions like 4K, the graphic rendering load on the GPU increases exponentially, making the CPU performance less critical.
