A native ESXi driver for the SVGA adapter that appears in a nested instance when ‘Accelerate 3D graphics’ is enabled to provide Xorg with OpenGL/Mesa acceleration in the same way an Nvidia/AMD/Intel driver does on a physical host.
Such a driver already exists for the SVGA adapter in Linux so this can’t be too difficult. If I had access to SDK/DDK’s for ESXi I’d attempt it myself.
I understand this would never be supported but it would improve Horizon View test/demo scenarios and 3D acceleration also has some use at the console for DWM acceleration (if it’s Windows, other window managers on other operating systems as well).
