DirectX, Xlib, windib, framebuffer ?

(+ 8bpp/palette functionality)

Reason is for 'legacy' hardware performance issues...

For example, I have an old COMPAQ PRESARIO 5140..
Windows 2000 Professional
400 Mhz Pentium II
384 Mb RAM
4 MB ATI 3D Rage LT Pro AGP 2x

It has OpenGL 'support', but is *extremely* slow. Rendering a -single- small sprite once per frame results in only 13 FPS... Whereas if I use SDL (which uses either the windib/DirectX backend, not sure at this point) I can blit about 600 sprites per frame at a constant 20 FPS.

Just saying.

SFML is not designed for prehistorical hardware, and I think there's no point doing it as there are alternatives. Just use SDL

Yeah, I suppose adding extra backends would change the 'S' in 'SFML' from 'Simple' to 'Super'.

It would introduce many bugs, make the whole library harder and harder to maintain, waste my precious time, and bloat the internal code (look at SDL). For 0.01% of users.

I prefer focusing on making the API stable enough, implementing the important missing features, and thinking about this kind of stuff later. Maybe for SFML 3
