I use to play at 1080p because I would get around 170 fps. That's the best I could get. And, just dealt with it. I had to cap the FPS or else I would get odd stutters. Otherwise smooth as churned butter on a hot day while sipping on some freshly squeezed pink lemonade. I found out that later version of win10 require you to use fullscreen borderless/window mode because of full screen optimization being kicked into overdrive peaking pass 11 while MS commits to "just send it". All of a sudden I'm getting 170+ at 1440p after some updates about a week or so go. And it's been that way every since. I've been on this driver for well over a month now so I didn't upgrade drivers. Although I do wonder if the driver team had anything to do with it. IE: We already had drivers for this game but took the developer to code for it??? Just a random thought. But Vanguard is around the corner now. And, although I really appreciate being able to now play this game at 2K at higher FPS (because it was definitely lower before). I do hope I get this kind of performance from the get go. Because I do recall using borderless mode before months ago and it made absolutely no difference in frame rates. Not sure what changed now other then some silent update that wasn't found in the patch notes. Strange...These mini cod updates are like a box of chocolates.
