Re: [Xen-users] 3D acceleration

[Daniel Spies <daniel.spies@xxxxxxxxxxxx>]

Trolle,

thank you for this! Just to be sure: Does this mean, I'll have full
DirectX10 support in Windows Vista domU? (Probably buggy, but working) I
just don't understand why there's this whole discussion about this being
impossible, and now you tell me it's possible with full 3D acceleration and
native drivers...

If you say that's true, I'll go straight to my hardware dealer and get that
VT enabling CPU :)

Compiling that stuff myself is not the problem, thanks for the warning!

Cheers,
Daniel
