Start with stable frame times and a sensitivity you can verify, then adjust visibility and latency settings around your actual hardware.
Open interactive TapLab ↗400–800 DPI is a common precision-oriented starting range. TapLab’s interactive builder targets roughly 700–1200 eDPI for many precision profiles, but your comfort matters more than copying another player.
Use fullscreen, your monitor’s intended refresh rate and a stable frame-rate strategy. NVIDIA Reflex is the in-game latency feature to prefer on supported NVIDIA hardware; test Boost rather than assuming it is always superior.
Boost Player Contrast is a sensible visibility-oriented baseline. Shadow and anti-aliasing choices are tradeoffs: reduce cost when GPU-bound, but preserve information you actually use.
16:9 native and 4:3 stretched are both preference-driven. Stretched models are visually wider but do not create extra game information.
Begin near neutral brightness/contrast/gamma and increase Digital Vibrance gradually if enemy separation improves without crushing detail.
