Mouse Jittery and Controller smooth
I've had this issue like many others, fought with my mouse and settings. Probably 20+ hours messing with stuff to try and sort it...Seems like it's similar to the 2042 issues they fixed after a long time of people battling it. I saw a comment on a youtube video that seemed to help out. I almost think it's a DLSS issue where it works smooth for a bit and then it disables itself.
This may help some of you but not others.
Open Nvidia App --> Graphics --> (Under Driver Settings) look for DLSS Override - Super Resolution Mode and change this to Custom and insert 75%. Reboot and cross your fingers. This has smoothed my game out tremendously. It still acts up sometimes but is day and night better than it was.
Something is broken here and honestly it would be nice for EA to acknowledge there is an issue and that they are fixing it (sooner than later). There are tons and tons of people with this issue so to not see much action from EA sucks.
