Hrrrmmm, maybe my understanding of how the OpenGL integration works. Could you please elaborate?
My thoughts would of been that the Virtual graphics card presented by the GAs is OpenGL enabled. This would then capture guest calls to OpenGL, send them from the guest to the host, the host would send them to the physical graphic card, the output buffer would be transfered back to the guest to the guests virtual framebuffer. This could then be sent by the RDP server. Maybe I'm far off. We aren't after the fast graphics, but rather the access to the graphics card to do maths functions (Matlab) Is this the right forum to discuss this? - James Quoting Frank Mehnert <frank.mehn...@sun.com>: > James, > > On Wednesday 17 June 2009, James Lucas wrote: > > In our case we use various software packages that can use OpenGL (eg > > Matlab 3D), all of these machines are accessed through RDP (VBoxHeadless). > > > > When I ran benchmarks between OpenGL enabled and disabled directly > > through the GUI, I got a performance gain of 4X when OpenGL was enabled. > > So for us it does make sense to have OpenGL accelleraton support when > > running VMs through VBoxHeadless. > > Hmm, but how do you want to forward OpenGL accelleration through > RDP?
