hi,
below is the error output when requiring vertical sync.
so, I wonder, simulated video card dose not support this function call ?

This is Decode Call Back String!
WaitForVerticalBlank 1 err: 80004001

主题: Re: [vbox-dev] on Vertical synchronization support of simulated videocard
in Vbox
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.

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 ?
