OK, imagine this scenario...
You've just finished writing a nice pixel scrolling routine, you have a
large number of sprites bouncing around on top of it and now all you
need to do is to add some sound effects. Easy huh? - Not really...
I'm programming modex and have the routine running at 60fps no problem.
As soon as I initialise the sound I start getting jerks in the motion,
if I cut the number of sprites down to, say, 1 then I still get the same
problem, what's going on?!!
I am using Allegro (thanks Mr H.) for the graphics and sound, but have
also tried the MIDAS library & SBDJ_05 (something like that) for sound.
With both I still get jerks.
If I actually play a sample the problem increases X-fold.

Can anyone please help, I'm getting desperate!

PS I'm using all the optimisation options.

PPS I want my A1200 back...(but with more MIPS!!!)

Remove the NOSPAM... to reply.
