Yep, I play it 1280x800 and it loses partially quality due to the interpolation, but I prefer a 24" wide
I have 1920x1200 available though unplayable. The demo has problem with resolutions on my vista64 machine. Initially when I started it the mouse cursor was confined to a small part of the screen and was unable to click the buttons. After swithching the resolution using the keyboard control somehow things started to work. Now I experience weird tremedous lag during game sometimes as if my mouse does not work at all. Never happens in other games.
