For me it seems that starting the XORG service did it. I kept my VM (v9) that I had used and it cut the available pool by 256Mb.
Odd thing is I set the pool to use 512Mb. I did see my Windows performance index go from 3 to 6 under 3D performance. I will try 3D Mark next for a more accurate reading.
Anyone have any thoughts as to why only 256Mb is being reserved? Also, anyone else get this to work on a card besides NVIDIA GRID i.e. maybe we can create a "it works" list of video cards.
(Full disclosure - I am running this on a modified GTX 680 into a GRID K2 with 1x GPU and 2Gb of vid RAM soooo.........it's a little MacGyver)
