What limits performance

Estimates above: GPU-limited, assuming a processor fast enough not to hold the Radeon RX 6400 back.
Processor needed for ~120 fps: Core i5-9400F or faster (slowest current desktop CPU our model expects to keep up).
With the recommended CPU: CPU-limited at 1080p high: about 90 fps instead of 120.
