I'm running WOE2 on XP with lower end machine and DX9,it runs great.
You might have to turn down some graphic functions,but it runs very well.
Absolutely agree. I actually get as good or better FPS on WOE2 than WOE given the same settings. The real killer with my lower end machine is the TV display (in the A-10 for example).
I think TW did some tweaking with graphics with the gen 2 sims.
