[A83] Re: Why is my program so slow :(
The reason your program might be 'slow' probably is because you use floating
point math. Calculating a sine or a cosine in asm is as slow as in basic
simply because you use the same code to do so. Games like Penguins or any
other game are 'fast' because they don't use floating point numbers, they
make direct use of the processor to calculate a few things, not as in basic
where you (have to) use floating point numbers for even the simplest
calculations. That's actually the main speed gain in asm. It's all in the
small, little things :-)
