Works in Fullscreen but not in Windowed

[Z4ng3tsu]

Hi all !

So my problem is simple to understand. The game work good in fullscreen as I said in the thread subject but when I edit the configuration file and set Fullscree=false, i get the message that my video card doesn't support vertex shaders when i launch the game. Which is not true because i can play in fullscreen.

Anyone know how I can fix this problem ?

Thanks
