Hi, we do a sportproduction 1080p 50fps with 5-7 cameras. Replay with 4 cameras.
We have a system with X299X AORUS MASTER, Intel Core i9-10980XE 3,0 GHz 24,75MB, 64GB DDR4 2666MHz, GPU Quadro RTX A5000, BMD DeckLink Quad 2.

After streaming a couple of hours the render time starts spiking causing dropped frames.
If I restart Vmix everything is normal again for some hours.

I can´t see that we should be low on memory, or that something gets overheated?
I don´t even have to restart the computer just close and restart Vmix and start streaming again and everything is fine.

So the workaround right now is to restart Vmix between games, but it would be nice not to have to do that?

Any suggestions where to start looking for a fix?

Check the power management settings on your Nvidia driver.

I usually see this kind of behavior, huge spikes in render time under even moderate load, when the Power Management Mode (under "Manage 3D Settings") is not set to "Prefer Maximum Performance".

The other option, which I believe is the default setting, is "Normal".
