hey I bought starcraft 2 and it is constantly lagging when I play, I have defragged the HDD and Ive cleaned up my system a couple times but it still continues to lag and i was wondering whether there is a way round it to play it without upgrading my PC? It is 4 years old but it runs other games really well but starcraft 2 doesn't work like it should.
