Vanilla setups (no curves or boost) work very well in Warzone.

The 4k dpi setup gives a slightly larger AA bubble but feels easier to enter the hit box. The 12k setup shrinks the bubble but is “stickier” once inside. I switch between these two setups depending on how the game feels on a given day. The way the servers are it’s hit or miss with how strong the AA feels.
