One Computer two Users "help""help"

I have been at this for week's google this and that, Seen software such as BeTwin,Vmware etc.

I would mostly like to know if there is a MS software to do this,
WITH 3D.

With Vmware i did install of Xp. also done others.... and dc'ed the other mouse and keyboard from "Host" my computer. and it worked but crap of 3d.

BeTwin works like a dream but don't support 3d at all "only for host"

I don't know if i can do this with windows server...I would like to use this for games "low end"
my specs are.

plus it's not a bad project.

Thank's
any help welcome links any thing i look like them guy's on bing commercials!

I'm not sure if there is a way to do that

Game and 3D stuff is some of the most demanding software. Regular apps you could probably set up to have 2 people use one server machine, but for games/3D even if you got it to work you probably wouldn't want to use it.
