it seems full screen is borked . i normally run 1920 1080 on a gysnc monitor
interval one . i normally am able to window out and come back with no issues . there is a big delay aT the moment in doing so and when i do come back into game my fps has droped by 12 or so from 60 to 48 . only way to fix it is to change the res or something that resets the screen then it comes back to norm of 60 . i tested in dx 9 there was no issues windowing out of game and coming back as fps stayed at refresh rate
all fixed for me thank you 10/15
