I have gotten a server set up with Windows Server 2016 TP4, and deployed RDS on the server. I installed several applications that use several different rendering technologies (including OpenGL), and I am seeing no difference from RDS 2012 R2, even though I have enabled 1Gb of RAM for the graphics. The video card shows up on the client VM as Microsoft RemoteFX Graphics Device - WDDM, and is not recognized by any of the applications as a compatible card, so they have problems with hardware acceleration. For example, AutoCad 2016 does not allow me to enable hardware acceleration because it says my graphics card is not compatible. It is the same experience that we get when using RDS on Windows Server 2012R2.
On the server, we are running an Nvidia Grid K1, which is the top recommendation from Microsoft. I was not able to install the latest Nvidia driver, because it says the OS was not compatible. The only driver I was able to install successfully looks like it was from 7/2/2014 - 340.52. This is the only thing I could think of that would not allow RemoteFX to function properly. If this is most likely the cause of the issue, any information on a workaround would be great. I have tried to manually install the driver through Device Management, but it says that the driver is not compatible also.
I know my question is not specific, but I'm hoping that if nothing else, Microsoft becomes aware that the advertised improvements in 2016TP are not working - at least in our environment. I would have thought there would have been much more documentation about workarounds that might be required for the Grid K1, since that is the top recommended card, but I found nothing - Nvidia doesn't even mention 2016TP. My thought is that if the issue is the graphics driver, then Microsoft would have had to work closely with Nvidia on the driver, and there would be documentation somewhere.
I have been looking forward to the RemoteFX improvements in 2016 for many months, so it is pretty disappointing that I'm not seeing any change in performance.
