Solved OBS stream recording – recording settings

Hello,
I have an NVIDIA GeForce RTX 4060 graphics card and an Intel Core i5-14400F processor.
What exact settings should I use in OBS under the "Recording" tab to ensure that stream recordings (e.g., Netflix) are smooth and don't put a heavy load on the computer? Which encoder and rate control mode (CBR, CQP, etc.) would work best with this setup?
Thanks in advance for your help!

First you have to make sure the video compressor is NVEnc AVC or NVEnc HEVC, so it uses nVidia CUDA hardware acceleration. Then use a high bitrate to eliminate artifacts. You can later edit the video in a suitable application and save the edited video with a lower bitrate. I use NVEnc HEVC with at least 10000Kbps for 1080p video. I have set the frame rate to 25fps (I leave in Greece, EU) so I don't have to convert it later. For USA you can use 29.97fps. If you are recording a game set it to 60fps. Also I compress the audio as AC3 (aka Dolby Digital) Stereo 192Kbps. This is equivalent to MP3 192Kbps which is very good, since even 128Kbps is considered CD quality. Anything higher will not make any perceivable difference. Have in mind that Netflix might give you a black screen if you have it on a second monitor and try to record it. You must have Netflix on the primary monitor and the connection must be either HDMI or Display Port. For best image quality use the dedicated Netflix application, not any browser. Only the Netflix application and Microsoft Edge can show 1080p or higher. The other browsers are limited to 720p.
