Well basically i cannot get to run the game in a good resolution for my screen (currently 1400x900), the window of the game is so big that is unplayable, ive tryed with many diferent resolutions, nothing seems to work.
idk if this will help you out but for me … I had to go into my NVIDA control panel and in Display -> Change Resolution -> then select a resolution under the PC heading … I had been running in a resolution nder the Ultra HD/HD/SD heading and was having all sort of trouble like what I see in your ss.
If you can get into the game, past the character select screen, press alt + f2 to cycle the windowed mode resolution. You can also do alt+enter to go full screen.
