I use mouse speed cranked all the way up. Quick seat software. TWEAKUI to eliminate multiple clicks to bring tables to foreground. Turn off animations. Hi speed connection. 1600x1200 Monitors. Apart from these things you can play 8-20+ tables for awhile. When you go back to 4 tables it'll seem SLOW.... (BTW I know a couple people playing 16-22 tables without a problem, not sure why you are having a problem with 4)
