So it doesn't matter either way? Well, I'm currently developping in a
Pentium 4. But the intended machine for my game is an embedded system with
a clock of 400 MHz. And it's A LOT slower than in my PC. Maybe it's
because I used 1024X768 with 32 bpp mode. Is it possible for me to add the
performance while retaining my curent video mode?
