Requirements wise I am about in the middle for minimum and max. The game suggests that I run on medium settings. My specs are,
Pentium 4 HT 3.4ghz
PNY geforce gt 430 1gb 128bit
windows xp sp3
And this is just the campaign that is lagging. It lags enough to where its unplayable. Dont know how torchlight is requirements wise against starcraft, but i can run torchlight on high everything just fine unless there is a ton of activity then i get a lil lag.
