Optimizing Call of Duty: Black Ops 6 for portable PC handhelds like the ASUS ROG Ally (including the ROG Ally X), Steam Deck, and Lenovo Legion Go requires balancing visual clarity with the high frame rates needed for competitive play. Best Graphics Settings for Maximum FPS

Latency and input responsiveness Beyond raw FPS, responsiveness is shaped by frame pacing, V-sync behavior, and input buffering. Triple buffering and V-sync can introduce measurable delay; adaptive sync is ideal but not always available on the M Portable. Reducing render queueing, enabling any “low-latency” or “reduce buffer” options, and favoring uncapped frame rates (when thermals permit) help preserve a tight feel. Also consider in-game sensitivity, ADS (aim-down-sight) responsiveness, and controller polling/settings — they all compound with system latency.
Black Ops 6 has heavy aim assist, but on a handheld with small joysticks (Hall effect sensors on the Legion Go are great, ROG Ally sticks are looser), you need to lower your sensitivity.
