Dirt2.
I got this free with a new graphics card and I've been playing it ever since. As for racing games... Well I usually have a demo, of some racing game or othe,r on the pc so I can get my driving 'fix' but have neve considered buying a whole game. After playing Dirt 2 tho' this maxim may have to change..
I'm loving this game for sure. The graphics are great (with a tad of DX11 thrown in ) and really do impress at times.. Anyway here's a few screenies
