sdl faster than directx?

[Brujah]

I just recompiled my game for windows. Works basically, but is a lot slower there.
Is DirectX itself slower than SDL?

Depends on the situation. SDL encompasses lots of things and can be GPU accelerated or CPU-based. In general I feel SDL can be faster, but it depends on the computer.

Of course theres the fact that linux in general is just faster than windows.
