DirectDraw is more likely to have good hardware acceleration than OpenGL - especially a lot of the older cards have poor or no GL support. GDI blit isn't too bad either.

tried OpenGl:
very good with transparences/colorisation very bad with vcards below GeForce... Sometimes I need out -256color- bitmap=entire screen 800x600 or 1024x768. This is really slow, more slow than from DOS vesa functions. How it be possible speed-up? I do: 1. get each color from bitmap 2. form true color 3xbitmap from palette table 3. out this bitmap with oGL. very slow... but oGl function "outBitmapIndexed (or same name)" is more slow.. |
