This replacement .module file has an edited globals.graphicspresetdefinitions tag disabling TAA when using the "Low" anti-aliasing preset. I'll continue to update this every patch unless the method is broken.

Campaign Installation: Navigate to your games install folder, move to /Halo Infinite/subgames/CampaignS1/deploy/any/globals/, backup the original globals-rtx-new.module and replace it with the modded campaign version.

WARNING - I'm not 100% sure if this mod is safe in multiplayer, haven't seen a ban for this you but use the multiplayer version at your own risk.

Multiplayer Installation: Navigate to your games install folder, move to /Halo Infinite/deploy/any/globals/, backup the original globals-rtx-new.module and replace it with the modded multiplayer version.
