Awesome game, severely limited by hardware, loading times and parts of the pacing are painfully slow and there are insane pop-in issues, as well outright stops and hick-up's in the rendering and the entire game, they usually last for 5 seconds or so. The frame rate overall is terrible, it's the worst during in-engine cutscenes with regular AI threads active in the background, has to be well below 30 fps.
Technical issues aside though, I'm really liking it, I especially like slaughtering mercenaries, It think I've bagged about 130 or so now, I even took one down that was 18 levels higher than me.
