To be completely honest, while TW2 is a marvel of gaming, it's ridiculously demanding. Enabling Ubersampling is a dream, and people who do it are probably running 3-4 GPU's. I have two GTX 580's running SLI, and the frame rate with Ubersamplinng enabled is absurd, considering my system. I literally blast every other game with unimaginable settings. I play Bad Company 2, maxed, with x32 CSAA, and the FPS never drops below 120 FPS. I hope at some point CD Projekt optimizes TW2 with either full DX11 support, or tweaks the Ubersampling to be more friendly. That being said, there is no way to change the shadow settings. Dithering appears regardless of how high you have the shadow quality set to, making the shadows a little ugly. Even with Ubersampling, there are traces of dithering. I've even delved into the configs and tried forcing a few settings, but nothing really changed. What happens when you change the texture memory from it's default of 400?
A quick question: There is the ability to import a character from the original game, but what does that change, storyline wise? Does TW2 actually utilize the decisions made in the first game?
