Ive been playing it for almost 4 day. Everything was good and smooth. I was playing with 60fps all the time. But today game keeps dropping to 30fps after few seconds. When I alt tab it goes up to 60fps and after few seconds drops back to 30 again. Sometimes it also goes up to 60 after cutscenes replays etc. And again drops to 30.
I didnt install or changed anything within 4 days. Donno what to do and how to fix this. Can't play game like this. Helps will be appreciated.
Tested with other games assassins creed 3, far cry 3 etc. they are all working with 60fps..
