The XNA Framework allows you to program the Xbox360 and use some of the Xbox specific instructions in shader model profile xvs_3_0, xps_3_0. The Vertex Fetch is a very handy feature and I would like to use it more but it is not available on the PC so I don't.

vfetch dest, src1, Semantic [, name = value, ...]

    vfetch position,          vertexIndex, position0
    vfetch normal,            vertexIndex, normal0
    vfetch textureCoordinate, vertexIndex, texcoord0

Is there anyway I can get Vertex Fetch to work on the PC. I only want it for testing purposes and not for release. I was wondering if there are any developer drivers or hacks which allow you to do this.

I own a Sapphire 4850 Toxic, Windows XP 32bit, but am going to fully upgrade soon.
