I think that the only solution is to use 640x480 resolution, if you want to play in the windowed mode. Or play in full screen with 1280x720 resolution.
But i don't understand - why game can't start in window 1280x720 if video card not support this resolution?
Video card not support 1280x720 resolution -> game can't start in full screen mode with this resolution,
but in window 1280x720 - why not???
I'm working with my HP Pavilion dv7 in 1600x900 screen resolution.
Video card don't support 1280x720 full screen resolution (look a log in first message)
Why game is working only in 640x480 windowed mode? Why?
