How slow? how many frames per second do you get? and what are the
graphics settings in settings/graphics and advanced graphics set to.
Also draw distance what is this set to?

According to the spec that graphics card only has 128Mb of *shared*
memory so it has to share bus time to get at the memory, for a processor
intensive application that uses a lot of physical and graphics memory
this could be a bad factor.

Also how is the graphics chip connected into the system, on what bus?
Moving graphics things around is a huge overhead, i see *enormous*
difference if my graphics card is in my PCIex4 slot compared to my
PCIex16 slot. If its only on a x4 then this is not the best possible
situation.

You have 1GB of system ram which is normally acceptable (well is for me
under linux, no idea of the footprint of windows tablet).

How does your processor compare to other processors? I have no idea
about the processor, when you are running can you get a %cpu usage, this
can indicate where the bottleneck is, for example my amd64 runs at about
75% CPU all the time with the viewer, its my graphics card that is my
limiting factor.
