Hi there, we're commissioning our new X299 7820X i7 vmix system and are experiencing high render times even with a blank session - just the two inputs Blank 1, Blank 2

We have a 1060 6GB NVIDIA in there, windows 10, latest update 20.0.44
Just vmix running.
Cards installed are BM Decklink Studio Pro, BM Duo 2 and an intensity pro.
I have four screens (2 desktop, 2 external monitoring - multiview and preview), but even when disconnecting two of them, I get the same high render times.
Presumably this should be down to single figure ms numbers with nothing going on?
It sits at 40-80ms even when there's nothing doing.
Task manager shows GPU at 4%, memory at 28% (But I have Chrome open to type this)

Any thoughts on why this should be? It seems quite arbitrary as a couple of days ago, idle was single digit ms with a session loaded. (1 camera input, a few overlays an three unconnected vmix calls)
We are hoping to start using this in production in a couple of days and I'm stumped.

UPDATE: I checked in Processes and there were a bunch of NVIDIA Containers and Web Share services that once I ended the tasks, Render time down to 0/1ms on the blank session.
I discovered that disabling these services prevented them from propagating - now even with a full input session idle render times down to 1 ms.

This might be helpful to others - I disabled these ones:
NVIDIA Display Container LS
NVIDIA LocalSystemContainer
NVIDIA Telemetry Container

Yes its astonishing the difference it makes. Of course you cant then use the NVIDIA control panel to manage the monitors, but I would rather have the low render times.
The NVIDIA Container service just seems to propagate many instances including (32bit) ones. These seem to slow the ability for vMix to communicate efficiently with the GPU enormously. Our system just went from 80ms idle render time to 1-3ms!
