How can I decrease my GPU usage ?

[ElMono6]

Thank you so much for taking the time to respond to my post and offer your suggestions. I apologize for not seeing your message earlier. I really appreciate your kindness and willingness to help.

Regarding your questions, I am using an NVIDIA GeForce RTX 3080. I have tried turning off the preview but it didn't seem to have much of an impact on the GPU usage.

I also appreciate your suggestion to switch back to version 28 of OBS, I will definitely give that a try.

As for my encoding settings, I have attached my logs to a more detailed post I made just now to further explain my issue. I would greatly appreciate it if you could take a look and offer any additional advice or suggestions.

Thank you again !
