Is that a laptop? The 8600M if I'm not mistaken is a mobile video card. I have the same in my laptop. I am running the notebook build of the 185.96 drivers and it's working fine for me. I've taken some nice screenshots using this laptop.
Mine is the 8400M and when I first started the game, it said that my laptop may not be able to play so did I want to play on lower settings. I clicked yes and WOW the game looks like something out of the 90s. It is so pixelated, I have to zoom all the way in on my ship just to see any details. Is there some way to disable this? I have newest drivers and I turned everything up on the in game settings but no dice.
