It's really odd, I'm getting around 10-15 FPS. I'd consider 40 to be more than sufficient. As far as I know I have the most recent version of the game. It's playable with the soft lighting feature turned off (around 40-60 fps) but if I turn it on and get near a torch it has dropped as low as 5 fps. I didn't really see much in the way of this problem searching through the forums so I thought I might have had something going on in my system. I'm okay with playing it without the soft lighting, but man it sure looked pretty. I've attached my darkmod.cfg file if that helps. Thank you guys! I can't wait to dig into this beautiful game!!
