well your ping is going to be pretty high(laggy) with a dial up, the best advice I can give you is get a bigger pipe(heh, pipe)

but some tips would be to stay in smaller games, that are generally have the lower pings. You can turn all the graphic settings down to there lowest.

Also make sure your computer is up to date, Good graphics card, decent cpu, enough ram.

All this will make your game run smoother(lower the fps) but you will still be proned to lag, with a dial up.
