XenServer documentation only covers using GPU Pass-Through ("vGPU") to run XenDesktop's "HDX 3D Pro Graphics." XenServer GPU Pass-Through cannot be used with the XenCenter VNC console and it does not appear to accelerate apps over Remote Desktop.
So is there some way to use GPU Pass-Through to run 3D apps without XenDesktop?
(My use case: I will be setting up 2 Windows 7 Enterprise VMs that 2 users need to run old specialized 3D applications on. I am fairly certain the apps use direct3d instead of opengl. My backup plan is to use ESXi 5.5 free edition with its software 3D rendering.)
