I can help you with the fps btw. Download amd disk cleanup utility and run it and it will ask you if you want to run in safe mode and say no and do the other shit correctly and it will ask you if you want to restart and say yes and then try playing fnf and the fps should work better
i don't really care about this anymore so i'll leave the thing here (warning: old and baaaad) drive.google.com/file/d/1kU6uceclfNOB4DRmInHcC3PezSYqCn1A/view?usp=drivesdk
