One last question regarding full screen mode...
My Textures and such render perfectly happily in Windowed mode - yet in full screen mode, they dont render at all... :S Any ideas?? (The same applies even if I start the game in full screen mode and then Alt+Enter to windowed mode where the textures appear again)
Can you post your drawing texture code. The only thing I can think of without seeing the code is that you might be using invalid coordinates, i.e, if the texture rendering method is something like this:
drawTextures(originX, originY, sizeX, sizeY)
(originX +sizeX) is out of the window.
Anyway, is this only happening with textures or is it happening also with 3d models?
