Multi Machine Setup delay

 

Hello together,

i have a litte issue with my Multi Machine setup.

I have a virtual screen in my UE file.

If i switch the content on the virtual screen there is a delay about 320ms between the screens on Machine A and B

Both Machine have the exact same hardware and die SDI Input for the virtual screen is provided by an SDI Splitter.

The only difference is that machine A is my local render and machine B is a remote render.

Is that "normal" that the remote Render is faster than the local render ?.

I also checked the load of the Machines and they are the same. The only difference (by 1%) is the GPU.

I´m thinking about two solutions:

1: Don´t use Remote rendering eg.: Copying the Unreal Projekt from A to B an use Local rendering on both.

2: Use a third PC with aximmetry an NO CAMS to Remote Machine A and B

In the first case I need to split all my remotes (Streamdeck, GMA etc.) to both machines because the community DE Editions doesn't allow any (practical) remotes. 

I hope that the Aximmetry Team can provide a useful solution to that issue.

Kind Regards 

Frederic 


P.S.: Yes I have read the guide how to setup a MM Setup ; )

Hi,

There is certainly a bit of delay because of the communication. However 320ms definitely seems to be excessive.

Can I ask what kind of content change are we talking about?  Is that something that requires UE to load a bigger chunk of data from the disk?

Hello Zoltan,

it is a screen inside my Unreal Projekt feeded by Aximmerty. The Content is a 1080p @50.

So there is no bigger chunk from the disk. As a wrote above the content is provided by an BM capture card via SDI into AX into UE. Like all the tutorials said "How to make a Screen in Aximmetry" .

Hi,

OK, so there is a virtual screen that is fed with an SDI input.  In this case you had to split the SDI signal and lead it to both machine, is this correct?

If yes, then there absolutely should not exist such a big delay, because both machine handles the input locally.  Are you sure the SDI signal does not suffer any delay for the main machine?

After a reinstall of Windows the dealy is in a small range between 1 or 2 frames.

Maybe it was a  driver issue with the BM Capture Cards.

Now i can´t reproduce the problem so it´s fixes : )
