I haven't had any trouble using DirectX's clippers. I've heard that they're slow, but I haven't noticed it.

Use directx's or your own,I personally havent noticed a slow down with directdraws. Why would it be slower? Clipping is a pretty simple matter,given there are ways to speed it up ,but in general i imagine the performance of directdraws is fine.

Whats the best way to do clipping with directx?

* DirectX Clippers?
* ->Blt(&dest_rect,...,&source_rect,....,...)
* something else?

The DirectX clippers are REALLY slow on my computer. It's really strange because I can run Quake 3 at a decent framerate with my 2 year old 3d card. (NVIDIA RIVA 128)
