Full window (800×600) blitting (both opacity and transparent), compare to GDI/SDL/DirectDraw:
32 Bits Blit
Opacity
Transparent
BasicBitmap C++
fps=2325
fps=1368
BasicBitmap AVX/SSE2
fps=2904
fps=2531
GDI
fps=2333
fps=1167
SDL
fps=2671
fps=1015
DirectDraw
fps=2695
fps=2090
Note: use BltFast with DirectDrawSurface7 in System Memory to perform Opacity & Transparent blit. BitBlt and TransparentBlt(msimg32.dll) are used in the GDI testing case.
16 Bits Blit

fps=4494
fps=1253
BasicBitmap AVX/SSE2
fps=9852
fps=2909
DirectDraw BltFast

fps=861
Blitting performance in SDL & GDI are slower than DirectDraw, just compare to ddraw as well.
8 Bits Blit
Opacity
Transparent
BasicBitmap C++
fps=11142
fps=1503
BasicBitmap AVX/SSE2
fps=18181
fps=5449
DirectDraw BltFast
fps=14705
fps=4832
DirectDrawSurface in Video Memory takes the benefit of hardware acceleration which is definitely faster than BasicBitmap. If you really need hardware acceleration, use OpenGL/DX as well.
BasicBitmap is a software implementation which aims to achieve the best performance in all other software implementations: like GDI/GDI+, SDL/DirectDraw in System Memory, for examples.
So just compare to DirectDrawSurface in System Memory. Use it in the condition that you only need a lightweight software solution: GUI/Cross Platform/hardware unavailable/image processing/video compositing, etc.
