FPS and G sync Issues after patch

Hi im heading into my second day of problems with PoE. Firstoff in windowed borderless my fps is capped to 59, and my cpu usage is at 16%, when I click outside the game to my side monitor I see the fps jumps to 200+, and my cpu usage is 50%. Why is this happening? In fullscreen mode it is working fine fps is uncapped. All g sync seems to have stopped working I am seeing screen tearing all the time even if I turn v sync on. I have turned v sync off globally, and my fps is still capped at 60 in windowed borderless, game in unplayable as it dips often and tears this is also with g sync on. I am using a gtx 980 ti, i5 4690k, and XB280HK acer monitor. I had LITERALLY no problems 2 days ago everything was working fine, driver have been the same version for a month now, no updates. I cannot figure out the problem it seems to be something is wrong with cpu utilization. Any help will be greatly appreciated.

I have the same issue. My fps is capped at 60 and when using a side monitor it spikes up. I am running an Nvidia card as well GeForce GTX 1080, an i7 5820K, and a XB281HK monitor. So it is almost the same setup and after the patch it starting doing the same things. Anything to remedy this would be great. Fullscreen is not fun to play in while tabbing in and out.
