Simple fix for the awful performance, until Fromsoft eventually fixes it.
Fix for the Stuttering Issue
- Launch your game
- Open Task Manager, go to Details tab
- Right click on armoredcore6.exe -> Set affinity
- Untick all cores except UC 0, press OK.
- Tab back into the game (it will run like poop, it’s normal)
- Go back to Set affinity again, tick all cores
You have to do this everytime you launch the game, but it takes a few seconds.
