I'm trying to find a good balance between performance and quality in terms of streaming at 3500 kbps for twitch.
In OBS under 'advanced' I have the preset section to use the NVENC encoder. Unfortunately, I can't use most of the presets. For example I'd like to try the preset 'streaming (2pass)' but if I select this preset a notification appears that the encoder couldn't be initialized. What's the matter of this?

I am trying to use different presets to find the best quality/performance balance. What's kinda weird is that if I stream through ShadowPlay it has minumum frame drops and still very good ingame performance, which I can't reproduce in OBS like that. When I'm using ShadowPlay there's no sort of drastic pixelation like using NVENC. It seems to me, that downscaling to 720p is done in OBS and the encoding by the GPU. I think ShadowPlay somehow handles that differently, at least. Thanks for any help!
