   Unwanted texture stretching
  Hi. :)I have a DirectX problem in fullscreen mode. When I have my camera looking directly up let's say that everything is alright. But if I rotate my camera ~90 degrees (it's still pointing on celling) the texture of my room is streeetch, so it gives an illusion of changing shapes.  I've got panoramic screen so the feeling is even bigger. When I run it on windowed mode problem still exists, but only until I make my window to be square, eg. 800x800. If it's important, my room in program is a cube, so all the walls are the same size.Can anyone help?   
  I suspect it's to do with your projection matrix not being set up correctly: you should pass in an aspect ratio when creating it, which — assuming square pixels — is the viewport width divided by its height.   ;  Thanks! I had this parameter set on 1.0f instead of 1.6f (1440x900 is in 16:10). Now everything works fine. Thanks one more time :)
