Disable render during PixelStreaming while device is waiting for connections

Hello

Anyone know how to disable or decrease the load on the GPU, while waiting for pixelstreaming users to connect?

Ive tryied a few things but with no succes.

We are building a Pixelstreaming service, and each computer on the network still remais with 35% of the load of the GPU, even when there are no one connected to the stream.

Thanks a lot.
