Instruction[9] Instruction Disable SLI at the system level, even if it's disabled on the game's profile. The game tries to use it which severely hits the performance. Make sure the card for PhysX is the same card that's rendering the game (GPU #1). DO NOT dedicate the second card to PhysX.

DO NOT use the second card or the CPU for PhysX.

Both of these will either cause massive performance hits, FPS drops, or stuttering. If you've done both of the above and still have 5-7 FPS make sure to disable these overlays (in this order, depending on what you have installed): RivaTuner Statistics Server (makes FPS go down to 5-7) Discord overlay (may crash the game on certain hardware) Twitch overlay (same as Discord) UPlay overlay (stupid I know... but it crashes or causes performance hits in some of Ubisoft's own games...) Steam overlay (if disabling all of the above doesn't work) If you still need a boost in performance, set process priority to High in the task manager.
