Yes it takes the load of either your video card are ur processor, not sure which , but i noticed much smoother gameplay after they were enabled...BTW doesn't matter wut processor you use they wont conflict. So you can use all cmds with no worries.
I think gs review was crap, not because of the score but the review itself. Im on coastline, game is awesome can't get enough of it so far... I would give it 95% from wut i played so far.
