I'm playing on windows 10 with steam and changing my game to fullscreen mode no longer works. There is currently no difference between fullscreen and borderless windowed. I see in known issues, there is a reference to the mouse not being locked to the window when using fullscreen mode but that is not the problem, the problem is that fullscreen mode is not actually working as fullscreen mode. The following problems are caused by the issue. Framerate and performance is no longer as smooth, aiming down sights at any target is now choppy, the game is no longer as responsive to my DPI, lighting looks different and more is now much more washed out, and antialiasing isn't as consistent as it was before. What is the timeline on this fix? I'd rather not play the game at all until this issue is fixed.
