So awhile back I bought a laptop to play Istaria with (mainly to run my one character to craft as I gather materials with the other), but I've hit a snag.

When trying to launch the game fullscreen, the screen turns black and then windows, then turns black, then windows, then turns black, then windows and it keeps doing this over and over again until I Ctrl+Alt+Del and tell Istaria to close (and it takes a very long time even doing this).

The game will run windowed, but yet I only get 20FPS (I could try reducing the resolution one size maybe), so I thought that fullscreen might increase performance a little, but I can't get it to run fullscreen without the glitch.

Anyone see anything like this happen on their computers? If so, how did you fix it?
