I recommend starting by using the Quality preset, and see how your performance is. If things perform poorly, you can reduce to Performance or Max Performance. Max Quality and Quality are actually the same thing, except Max Quality uses two-pass encoding, which uses CUDA, which can have an impact on GPU usage.This option enables dynamic B-frames. Without this option, the encoder will always use the number of B-frames specified in the "Max B-frames" setting. If Look-ahead is enabled, it will only use the number of B-frames that it decides it needs to, resulting in better quality via better resource usage, but uses CUDA.There are some tools out there that can automatically grade video quality, but sometimes the metrics they use end up grading some things higher that have lower perceived quality to a human in certain situations. Enabling Psycho Visual Tuning turns on some options that sacrifice these quality scores but may increase perceived visual quality, but also uses CUDA. For example, this might end up having a better effect on things like grass, but might degrade something else. It can be subtle and nuanced. I encourage you to give it a try and see what you think.
