Your laptop's specs are very weak for streaming to Twitch. Other than that, we will also need to know your upload speed, as this will determine the maximum bitrate you can push to Twitch without overloading your ISP and dropping frames.
uh there is no NVENC encoderGenerally you can just go to the Tools menu, then run the Auto-Configuration Wizard to get good baseline settings.
That said, your hardware is indeed on the weak side for livestreaming in general; U-variant CPUs are 'ultra low power' models, optimized for battery life rather than performance capability.
Using the NVENC hardware encoder is strongly advised. Your 920M GPU should have it available, though you may need to update your GPU drivers from nvidia.com to get it working.
you can search up on Youtube and look at the latest and highest view videosAre there any low settings on obs for streaming in a low-end pc? If so, please do say me
