I'm surprised to see how much a Pentium2 300Mhz MMX on a Matrox G550
spanks my Voodoo3 3500 on a dual AMD 1800+ XP. This makes it quite obvious
that we're really depending heavily on hardware acceleration especially
for all things alpha channel :P So, two questions:
1) Are there any speed ups for software based rendering that can be done
but have not yet been implemented? The project I'm working on depends
heavily on alpha channels so I'd be very interested in any software speed
ups we can get. and
2) Are the alpha-channel hardware speed ups dependant on some kind of
hardware feature? I know some recent cards have made a big woopdie-doo
about anti-aliasing in games. Are these features DirectFB is tapping into?
After this repost of his Matrox G550 on a Pentium 2 300Mhz is a repost of
my benchmark, and then the same system without hardware acceleration. It
really drives this point home.
