If I switch to full screen 1920x1080, only left side of my screen draws. I never had this problem with any of the older versions of SL. When I run in a window, everything is very choppy. I have more than enough horse power to render 1920x1080 3D graphics.
There are no configuration settings to force SL to work correctly that I can find. I dont have any issues with other 3D games that use DX 9 or DX10.
Im using Vista with the latest WHQL Nvidia drivers using an Nvidia 8800GT (most advanced Nvidia GPU: G92).
