Looks like a lower-end CPU, using CPU encoding, and ignoring the BIG warning sign about NOT recording to MP4 format (remux afterwards, if need be)
So asking about video quality is the wrong question. The question is either:
- what quality can you achieve with what you have?
or
- what quality do you want, and how much are you willing to spend to get that quality?
I'm guessing you are more likely to focus on making due with what you have .. right? if yes, you have a lower -end CPU, and trying 1080p 60fps, so GPU encode offload (regardless of quality) may well be required to balance workloads.
There are many threads on setup optimization for an under-powered computer. I recommend researching those for suggestions. And do not ignore making sure your Operating System is also running efficiently, reduced eye-candy type settings, and no unnecessary background processes running
As for the OBS log (mentioned in pinned post in this forum), last line of my /sig has link (and to the Analyzer)
