Vista - Bad 3D render performance of WPF in XP

I have created a 3D model in blend, and it could work well and animation is
smooth in Vista, but in XP, the 3D model's animation is jerky and the
performance looks bad. BTW, I tested it in the same machine.

Any expert has any idea?

Thanks.

I think fancy 3D stuff is software rendered on XP (even if the hardware -
video card has 3D acceleration), while Vista will use the hardware.

Is there any method or workaround to solve this issue?

If your window is not rectangular, make it so, as non rectangular WPF
windows on XP are not accelerated (or very poorly). For your 3D
objects, there's not much you can do except embed some "true" Direct3D
inside your app, or wait for the next version of WPF which (might)
solve the performance issue.
