Unable to render with multiple instances.

I am using v19.0 build 643. Windows 10. i7 CPU. I am editing videos from 4 courtrooms a day and need to be able to render them simultaneously. I was able to do this with v15, but v19 won't do it. It seems to be an issue with using the GPU. Whichever instance is on top of the screen, runs the rendering and the others make no progress. On v15, I have the GPU rendering turned off and it only uses the CPU (6 cores). I cannot find on v19 where I can turn off the GPU for rendering as I suspect that this is the problem. We are looking at purchasing a new computer and a new copy of VEGAS v20, but this is a problem that I would like to get solved before recommending VEGAS for the new computer. Thank you.

I can get the following results:

One Instance of Vegas 19-648 GPU Decode / Timeline Acceleration / Render to AMD VCE

Two Instances of Vegas 19-648 GPU Decode / Timeline Acceleration / Render to AMD VCE

Three Instances of Vegas 19-648 GPU Decode / Timeline Acceleration / Render to Voukoder

You may be getting into diminishing returns with more than two at a time. The bottleneck could be GPU, CPU memory, etc. ad nausea.

P.S. I have a new machine in a box but have been too distracted to put it together.
