I can get good 2d graphic speeds in UNdelphix using dibs or the pixelcore libraries that come with the undelphix. I can also draw bitmaps.

I can also do pixels with GLScene, using the direct canvas for 2d stuff. It seems to use the 3d functions of opengl to draw 2d. I have problems drawing bitmaps in this though.

Which one would you recommend?

Which give you faster performace? I find the GLScene is faster and I can do easy antialiasing.
