Hi Thomas,
Could you specify how exactly do you ask for "Vertical synchronization",
which does not work?
Setting D3DPRESENT_PARAMETERS::PresentationInterval to
D3DPRESENT_INTERVAL_ONE in IDirect3D9::CreateDevice should produce no
error as far as I can tell.

hi, all
now I have a windowsXP App that use DirectX technology to display the
high-resolution real-time video.
however, it works well in physic machine but not in vbox winXP vm.
finally, we find the root cause is that when we ask for "Vertical
synchronization" on simulated video card in VM, it reports error and
no display at all. if we don't ask "Vertical synchronization" , it
works well.
so my question is :
- does simulated video card in Vbox support "Vertical synchronization"
function ?
- is there any patch for this problem ?
