By how many milliseconds or microseconds? As long as you're not being
terribly inefficient with graphics (i.e. making system calls to plot each
pixel), there will be no difference. The main bottleneck as you yourself
pointed out is the math.
I would recommend that you look into the SSE/SSE 2 instruction sets. At a
minimum, they offer scalar FP with flat registers rather than the x87 stack.
You may also be able to take advantage of vectorization.
Though it is off-topic here, I will also mention that there is a great
library called SDL which handles graphics on both Linux and Windows. You
might look into using it as it will simplify porting your program.
