I upgraded my on boad video drivers and am having much better performance on my machine.
For users who are getting 2-5 FPS make sure that any where the device is getting set up that the DeviceType is Hardware and not Reference. Reference is really slow.
Now then, is anyone getting a really blurry/pixely skybox? In part IV I used the MSFT lobby images and they are super clear, but when they render on the skybox mesh it is like everything is out of focus.
