Does anyone have any suggestions for improving the input and response 
time in SDL-based games (in pkgsrc/games)? I'm noticing the following 
problems which make it nearly impossible to play games such as (e.g.) 
lbreakout2 competitively when my opponent is on Linux.

. Sound events happen a fraction of a second after the triggering event.

. Mouse response-time is a fraction of a second subsequent to the 
movement of the mouse itself, and can be jerky at times.

Most of the SDL-based games are like this, and I thought I'd gotten away 
from that kind of thing when I upgraded to an Athlon XP 2500+ w/ 1GB 

I guess I just never noticed these things in non-gaming use because they 
weren't important. So what if xmms takes a fraction of a second longer 
to play an mp3? Who cares of the mouse skips half the screen--it made 
it to where I moved it didn't it?

Anyway is there some kind of kernel options or sysctl settings I can use 
to improve both the speed with which a sound is actually played, and 
the responsiveness of these kinds of games?

Nothing else is running in the background, all other non-essential 
processes are killed, top reports I have a good half-gig free RAM.. and 
I'm at a loss.

I suppose it doesn't help that my Linux-using friend laughs at my 
computer. :)

Advice much appreciated,
