RAM vs. Graal lag

[Deek2]

Well, whenever my computer got an upgrade, i've been noticing terrible lag when I play graal. I mean like everyone lags. And the funny thing is my modem goes the same speed it did when my computer didn't get an upgrade, sometimes even faster. Soo I know that isn't it. But lately my computer has been getting alot of hangups cuz my RAM keeps running out of memory. Right now my RAM is 128MB, but 32 of that is shared with my onboard bideo card, soo basically i only have 96 . Could this be the reason why graal is lagging up soo bad?
