On my machine, I found a reproducable problem with Blackmagic Decklink Quad Hdmi Recorder input, resulting in periodic spikes which increase and decrease:
The Decklink is used with two inputs in 25fps. (No input is actually piped into the decklink card, but the behaviour also appears with videoinput)
The spikes appear alongside of a tiny gpu memory increase/decrease.(The two steps refer to the two decklink inputs).
Configuration:
- Windows Tower
- Blackmagic Decklink Quad Hdmi Recorder (installed Black Magic Video 14.2.1)
- RTX4090
- Intel i914900KF
- Touchdesigner 2023.12000 running 25fps
Does this also happen on other machine and can this be fixxed?
