I'm running it with a few problems on my old (built it around 2007/2008) pc. Some specs: AMD Athlon 64 X2 3800+ (Dual core, 2GHz) 2GB RAM ATI Radeon HD 5450 I'm running at 1280x800, trying to keep FPS up. Occasional crashing as I transition areas which I'm thinking is memory related. During some of the more "graphically intensive" moments (think when the biawac arrives at the end of the opening caravan section) I get some significant FPS drops. And before you chime in, yes I know I need to upgrade but I simply can't afford it right now.
