I just updated our R720's BIOS from 1.4.8 to 1.6.0 and applied the the settings you suggested in the BIOS. It made a significant improvement to playback performance. It appears that the last bit may be related to encoding the PCoIP data fast enough, I have a Teradici 2800 card I can try once I can get it out of our current View hosts, but that will take some downtime so it probably won't happen today.
Kindly share the output of following command
~ # nvidia-smi -pl 0
Kindly observe the changes and let us know will this help in GPU performance
If u have dell support take the help of them to optimize the BIOS settings. Here my local Dell Support is good for noting.
And also share the result of APEX card will it help in improving View environment / not.
I am having the same performance problems with the GRID K1 in a R720. For most tasks the nVidia card actually seems slower. For example google maps, from the default satallite view of the USA zoom in several levels. In a host without the GRID K1 it will take 5-10 seconds to render. With the GRID K1 card it will take upwards of 45 seconds, sometimes timing out and crashing the browser. Issue is repeatable.
Also of note, the nvidia-smi -pl 0 does not seem to be a valid command for the GRID K1. Says to pick a power rating between 10w and 31w. By default it is 31w (max)
Just saw this in the nvidia-smi -q output.

Current : 8x
What best can be done as of now is
Check the BIOS (BIOS.docx) settings as you see in my previous post.
Check the ESXTOP result CPU ready value should not exceed 5.
If all the above things are done from our end.
Try taking help of Dell support for optimizing BIOS even more.
Contact Nvidia and VMware support stating vSGA not working as expected.
Good luck kindly share the result.
Kindly share your inputs
~ # nvidia-smi -pl 0Provided power limit 0.00 W is not a valid power limit which should be between 10.00 W and 31.00 W for GPU 0000:09:00.0Terminating early due to previous errors.
This is what I get when I try that command.
I do see the performance level fluctuate but its always related to gpu utilization I go between P8 at idle and P0 when there's anything that taxes the GPU.

Are my results for the PCIe bandwidth, I don't think this is your issue though. I tried google earth yesterday and everything was very smooth. The thing that made the biggest change was updating my R720's bios to 1.6.0 and making the BIOS changes listed previously. I'll take some video right now of google earth running and post it.
How is your performance in the normal Google Maps satellite view and playing a 1080p video on VLC, host with GRID K1 vs host without?
That's with the Grid K1. I just started up my other test VM that is still set to software rendering, I'll take some videos of a few applications between the two and post the videos in a little bit.
Has anyone tried some of the graphic demos from AMD/NVIDIA?
I'm not sure if the AMD Leo demo will run on an NVIDIA card but the hair demo should run.
The problem with those is that the VM only sees a card with DirectX 9 and OpenGL 2.1 and even then I don't think its the full feature set.
Can you check 1080p sample video avail in Win7
Kindly share me the deatils about your CPU and storage where your VM is running.
Hum... I thought using nVIDIA's new Grid VGX K line of product would provide full compatibility with: DirectX 9, 10 & 11, OpenGL 4.3 as well as Cuda!
BTW, what about this software?
Does it have to be installed on the hypervisor to get full horse power from the graphics card and/or to unlock specific features?
If you look on that page, View only supports DirectX 9 and OpenGL 2.1. I find that not all the OpenGL 2.1 benchmarks will run though because of missing features.
Good point on the DirectX version. The big issue for us is scaling for # of users per K1 or K2 since there is a max of 2 cards per R720. It would be nice to see a comparison of what load some of the guided tours in google earth put on the different cards. Seeing the spec sheet of "low-end Kepler" (GK208?) with 192 cuda cores per GPU vs a "high-end Kepler" (GK104?) w/ 1536 cuda cores per GPU leaves more questions than answers as we don't know how their GPU virtualization layer splits up work on the CUDA cores, etc.
We have some student labs that use AutoCAD (and other CAD programs), some GIS applications (ArcGIS) and Google Earth. I'd be willing to bet that for us Google Earth will be the heaviest GPU load. It is fairly easy for even a novice to stress a GPU in that program and I doubt student assignments in the CAD programs will be all that 3D intensive. But it is important for us to ensure that Google Earth doesn't become a 1FPS slide show if 30 students in the lab are using it at once.
