Just becareful with Do3d and XP.

Floating point operations become single rather than double which can cause hassles it you add two Doubles together. We had problems where 2 + 2 = 3.999999 or whatever.

This only happens with Windows XP.

If you aree doing 2d stuff then zbuffer is false.

As for wide screen - you will haveto take that intop account during design.

Either stick to your aspect ration and wide screen users have black bars on left and right. Or increase the width of the game area.
