Optimisation VDI desktop with vGpu over WAN

Hello everyone, 

For 3 months now I have been trying to optimize the performance of my system as well as possible, but I cannot.
Description of the infrastructure:

 

2X:

 

2020-12-15_16h26_24.png

with 2x Nvidia RTX6000

+ MSA 2052

 

Everything is functional and has been installed following VMware documentation and best practices.

I'm trying to get smooth and constant 60 fps rendering of software running on client machines.
the internet connection on site is a fiber in 500 down and 100 up
My home connection is 400 down and 20 up

I tested all the settings in GPO Blast but can't seem to get a smooth and consistent image. I get 60 fps but it's choppy.

Here is attached the current GPOs

I need help, I am desperate.
Don't hesitate if you need more info.

 

Thank's

Here are some screenshots of the machine in operation. You can clearly see as soon as I move the mouse and the scenery behind the robot moves the number of images per second decreases. If I do a local benchmark, no problem, no drop in fps. But what comes back to me is not fluid. locally, no worries but through the wan it is jerky.

Is your Blast session running over TCP or UDP?  I have seen smoother screen rendering over UDP. Some network environments can make it tricky to get UDP working over a WAN session.  Also, which codec is being used and is it properly configured for offload to Nvidia - https://techzone.vmware.com/resource/vmware-blast-extreme-optimization-guide#sec2-sub3

Hello, I have tested both, UDP and TCP. In my case, TCP is the best suited protocol and the one that offers the least latency.

Regarding the NVIDIA protocol, I tested the H264 and the HEVC. In both cases the result is very similar.

I bring here a little more explanation.
I was able to test and I get 60 fps on the local machine.
The problem is therefore at the level of the Blast protocol.

Regardless of the image quality settings the fps sent decrease.
I tried lowering the quality to the minimum. Someone would have any idea ? I just wish I had constant 60 fps, the quality is not important.

Morning, 

Sorry to resurrect and old post but did you find a solution? I am in the same boat.
