First of all, my computer specs are ; i5 6500, Gtx 1060 6gb, 16 gb 2133 mhz ram and the game is installed on a ssd. My problem is after the latest UI update, I experience heavy fps drops and there...
I'm also experiencing these FPS drops. A year ago this game worked flawlessly, even a few months ago too. I recently played it again and I get these horrible FPS drops which make the game unplayable. Now my PC isn't exactly a beast by any means but I was playing this game fine on the highest settings. I tried playing on low and it still happens. The issue is with the game or the drivers not the hardware at this point. I verified the game twice, hell, I even reinstalled Windows completely and it still happens. My friend who has the same specs as me albeit the GPU (He has an AMD GPU) it doesn't happen to him which makes me think either something wrong with the game or the drivers. Although I can play every other game on the highest settings just fine.
