Hi! I'm wanting to try out the newest update with New Nvenc. I'm wanting to take the load off my Cpu so I can get a solid 240+ frames in Overwatch and at least 144fps in Fortnite. In my PC I have an i7 8700k and RTX 2070. What is the best settings for Nvenc. Obviously Preset Max Quality. Profile main? Since i've heard it's harder for mobile users to watch if it's set to High. Key frame set to 2. 6000 Bitrate. I'm not twitch partnered so I don't know what the cap is for non partners. Enforce streaming service encoder settings? Check or unchecked? What the difference of having it on or off? What does Look-Ahead and Psycho Visual Tuning do? Should I have them on and why? Gpu is set to 0 And Max B-Frames is set to 2. Should they be different? Sorry for the million's of questions. Thanks even if your not able to answer all of my questions! 😃

Hey there!

I agree with what you are choosing so far. Here's some additional information about look ahead and psyco visual tuning:

Look-ahead:
Unchecked for most content, checked for low motion games. This allows the encoder to dynamically select the number of B-Frames, between 0 and the number of B-Frames you specify. B-frames are great because they increase image quality, but they consume a lot of your available bitrate, so they reduce quality on high motion content. Look-ahead enables the best of both worlds, but struggles with high motion content as it needs to change too often. This feature is CUDA accelerated; toggle this off if your GPU utilization is high to ensure a smooth stream.

Psycho Visual Tuning:
Checked. This enables the Rate Distortion Optimization in the encoder, which greatly optimizes the way you use bitrate, improving image quality on movement.

Note on the new NVENC encoder:
- Current GeForce GTX GPUs, 600-Series and newer with NVENC, will see improvements with these optimizations.
- GeForce RTX GPUs will also see an improvement in encoding quality on top of the optimizations.
