Describe the Bug

Hello, I would like to know if you have noticed the same thing on your installations. Desktop streaming from Windows Host represents 35% of the GPU's TDP... Consumption goes from 20W when idle to 90W with no application running that requires GPU performance. I reverted to the November Nvidia driver without success. I tried the beta and previous versions of Sunshine, same result... I also tried with another client, Moonlight, with the same result.

No streaming active (idle windows)

Streaming active (idle windows) : sunshine > moonlight

On the NVENC tab, you can disable the option to prefer lower latency to lower power consumption.

On the NVENC tab, you can disable the option to prefer lower latency to lower power consumption.

I think this should be by default disabled. I found no degradation in my experience with it off. plus it saves a massive amount of power while your stream is idle.
