My nVidia GF5200 simply couldnt handle KR at all. So i finally broke down and went to Best Buy. I bought the VisionTek ATI Radeon HD 4670, 1 GB DDR3 yada yada, I paid $139.00 for it, and another 65.00 for the Power supply upgrade that I needed anyway, and WOW!!. I was running all around the inside of my house, which I"ve never been able to do. I could actually move the paperdoll around the screen without having to wait for an hour. The motion from walking speed on a Dog and running is a little weird, but the playability is definitely sweet. Now I"ve gotta read through the old threads and see how to tweak KR a little. I still love my 2D, but KR looks good to me now, so I'm going to give it a shot.....
