dedicated notebook for streaming

[Peerless]

Hey there,
i use a Lenovo L340 Notebook as a Streamencoder for Livevideoshows.... The machine just does encoding, nothing else. I use mainly the nvenc encoder(gtx1650), and want to get the most possible quality.

i tried a lot of settings and iam a bit confused maybe you can get me some advice

mostly i use 1080p/60
6mbit upstream, different plattforms (often vimeo)
max quality
profile high
2 keyframes (in my opinion automode gives me a little more quality)
lookahead checked
pvt unchecked (not sure if better be checked, checked looks a little more motion blurry to me)
2 bframes > more b frames does not look better to me

sometimes it looks like there ist some micro stuttering in preview and also the stream, could be a reason of the two graphic cards and the display is connected to the intel card ?

thanks

Use the Quality preset, not Max Quality. MQ enables 2-pass which isn't really meant for realtime video encoding, and uses CUDA cores as well.
Past that we would need to see a logfile from a streaming or recording session where the issue took place, to be able to troubleshoot the issue and see what's happening on the back end.

why don't use cuda ? the notebook is just for encoding, so it could be used as much power as possible.... whats wrong with 2pass ?
next question could be which kind of options in the nvidia system control could optimize the cuda part of the encoding....
