Hi,
When I run a winxp guest in qemu, I have bad experience in AutoCAD.
But in VirtualBox, AutoCAD works very good.

I checked graphic driver source code of both software, and find VirtualBox have VBVA function while qemu not.
I want to test if VBVA makes AutoCAD works better, so is there any possible way to disable VBVA?

If you're diving into the source code you will probably want to talk to the developers. See https://www.virtualbox.org/mailman/listinfo/vbox-dev
