Hi Roger - if the sluggishness is something to do with the 3D display, stuff like pauses or hiccups when you move the mouse around inside of viewports then that's likely to be some problem with the video driver and that makes it fairly likely that a native Linux version would still suffer in the same way on your particular machine / video card / driver setup.

When the video driver misbehaves it's difficult to make things work well...

Video drivers are even more problematic than other kinds of drivers since video cards these days tend to be the most complex piece of hardware on the machine.
