Allocate more RAM. Try not locking your FPS(Put it on max fps). Install Optifine, edit optifine settings. Remove potential HD texture packs.

The lag on SG5 is due to 1.5 with snow block i suspect this should be fixed soon as for SG2 and Asia Games i have encountered none yet (touchwood) anyway sorry
