Probably not. The "Direct" in "DirectX" means that DirectX has direct
access to the hardware. There is not a lot you can do at that point
other than dynamic compilation to inject sandboxing code.

And even so, after you sandbox you're not really sure what the state of
the machine is for recovery purposes.
