Good day, I think I encounter bug here. It actually started for me on version 457.09 and it still persists. When I set Max Frame Rate at 141 FPS (because I have 144 Hz G-Sync Monitor), everything works as intended, Nvidia Drivers limit FPS in game. However, when I turn PC off or I restart it, the above mentioned setting resets itself to off (like default setting). I never had such problem from time this setting was invented. I think the drivers are not saving this setting properly. Please, it will be good if you can fix that. Thank you.
 
EDIT: I use EVGA RTX 2080 Ti XC Ultra Gaming + Asus ROG PG279Q G-Sync Monitor.
 
EDIT 2: Ok, definitely a bug here. Re-rolled back to version 456.71 and I encounter no resetting or whatever. This nasty bug started from version 457.09 and persist in new version. Please don't go road like AMD with their drivers, why break something what it's not broken at all?
 
EDIT3: Ok, problem solved. This ''bug'' is in fact related to EVGA GPUs. Problem is with new Precision X1 v. 1.1.1. When you try to set FPS limiter within drivers (lets say 141 FPS) and set FPS limiter in Precision X1 v. 1.1.1 to off, after reboot/login off, your value in drivers will be off as well. In short, if you want use FPS limiter with EVGA GPU and with Precision X1 v. 1.1.1 installed, you need set FPS limiter in that program as well or it will not work, that value will reset every time you will go reset/log off from your PC as mentioned above. If you set any value in Precision X1 v. 1.1.1 and previously setting in drivers will be off, after reboot in drivers your value will be exactly same like in Precision X1 v. 1.1.1. So right now it seems, that Precision X1 v. 1.1.1 is superior to Nvidia Game Drivers in term of setting Max Frame Rate, which is funny. I am not kidding, try it yourself. I know that EVGA recently had some problem with fans on their GPUs with new drivers and Precision X1 program, but, that it is broken in this way, it is really unbelievable...

I have the same problem here, thanks so much for your debugging it, it solved.

I am having a problem where anytime i adjust ANY setting in precision x1 or even afterburner the screen flashes when on desktop, or in a game the game crashes, sometimes even causes system to reboot. I've tried everything i can think of. Moving the card around, reinstalling drivers, and even reinstalling windows 10..... to no avail. Bra it is maddening. Please help.

This will be fixed on next release.
