CPU bottleneck calculator for 1440p gaming

At 1440p, many players assume the GPU is always the limit, but frame pacing and 1% lows can still collapse when the CPU cannot feed frames consistently. This guide starts with proven pairings, then shows where to validate your own setup.

Use the database filters to lock in your CPU, GPU, game, and resolution. Then compare average FPS with the distribution view. Large spread and weak 1% lows are usually a stronger bottleneck signal than headline FPS alone.

If your low-percentile frames are unstable, prioritize CPU-bound settings first: crowd density, simulation distance, and heavy RT-side CPU overhead before replacing expensive hardware.
