Thanks.

3840 X 2160. That's the res I enjoy. When I disable the use desktop thingy that pops up when starting game and manually enter game res it works. Problem is windows menu at bottom of screen overlays game and blocks play button. Buggy!

Just purchased it. When trying to do single mission or other game returns to desktop. Deleted config files. No go. How do you disable that desktop menu that pops up in the beginning?
