Understanding GPU Bottlenecks in Modern Games
A GPU bottleneck happens when your graphics card is the limiting component for frame rate. Increasing resolution, texture quality, ray tracing, and visual effects generally shifts more work to the GPU. At lower resolutions, the GPU can render frames quickly, so CPU speed and game-engine performance often become more important. The best pairing depends on the game, refresh rate, settings, and target FPS.
How to use this estimate
Choose your CPU, GPU, and target resolution for a quick directional result. A high percentage suggests that one component may limit average FPS or frame-time consistency. Driver versions, cooling, background processes, memory configuration, and individual game engines can change real-world behavior.
