I am playing on a damn GTX 980 SLI + i5 3570K at 4.2ghz playing at 1440p ULTRA, my FPS bounces between 40-80 FPS occasionally, and there is nothing extremely extensive in this game to drop my FPS to 40 while just wondering in hinterlands (out of combat)!!!
The problem is :
I tried LOWERing setting, from ultra to high, and resolution to 1080p to always get above 60FPS, it doesnt work
NO MATTER HOW I PLAY WITH SETTINGS FPS DOES NOT GET EFFECTED BY IT, 1440p and 1080p has almost same FPS, changing settings doesnt work (at most 1-10 FPS from ultra to medium), besides FPS DROPS don't make sense at all, it happens while staring at a door sometimes. There is something clearly wrong with game.
And this computer plays BF4 at 100-144 FPS on 1440p everything on ULTRA, as far as I know they are same engines, and some of BF4 levels are as much as detailed (maybe more with all explosions and reflections) then DA:I
