Remote Play failed to load nvenc, and try to use vaapi for nvidia, but it is impossible.
Besides need a function to force choose video encode hardware, so i will use intel integrated gpu to do encoding jobs (I selected in the setting, but not work and keep trying load nvidia vaapi driver)

Hello @AnterCreeper, a non-fatal fallback chain trying to use vaapi as a secondary hardware based solution, and then continues to fallback to a CPU based encoder is not a bug. In theory something like elFarto/nvidia-vaapi-driver#116 could grow support for this path, but that's something that would need to improve in the video driver.

It looks like you need to have the libnvidia-encode1 and libnvidia-encode1:i386 system packages installed to support NVENC on Debian. If adding those packages doesn't help, then report the broken hardware encode path to your distro's package maintainer(s) for the NVIDIA video driver.

There's a feature request at #7215 tracking the request to try to be able to use a different GPU from the GPU rendering the game.
