AoE 4 making GPU consumption of other apps skyrocket. How to reduce?

When I’m running AoE 4 especially when playing a game in AoE 4 it at least 3-folds the GPU usage of some Apps from what they would consume while playing AoE 2 DE instead.
Hence this is a candidate to be some bug of or resource leak of AoE 4.
I observed this in combination with NVIDIA RTX Voice, Streamlabs OBS and OBS.

How to get their GPU consumption back to normal while running AoE 4?
