I got the game 1 week ago and the preset mode was ultra, so I let like that. The game was running smoothly with no frame drops at all , at constant 60 fps.
Today, suddenly the game just started to drop fps constantly. No other program is running in the background.
PC specs :
Intel i5 3470 3.6ghz
Sapphire rx 480 8gb nitro+
8 gb ram
1280x1024 screen resolution
The game is running from a HDD 5400 rpm
But as I said , first few days there was no problem with the game.
Any fix or reason of the problem?
