Anyone have advice for recording with NVENC AV1 (RTX 4090)

[Its Ryan Royce]

It seems like no matter what settings I change, the bitrate doesn't increase... Even rescaling to 4k recording Chrome 120fps, CQP 20, AV1 seems to not budge with visual fidelity. Is this by design? Or are there some weird settings that I have no idea about yet. I'm still baffled about how little info there is online about NVENC AV1 and how to configure it for recording (not streaming). The only thing I used as a guide was EposVox's video he made 5 months ago about recording with AV1.

I would rather not have to use my Ryzen 5950x for encoding so if anyone has any suggestions or can help me, I would seriously appreciate it. Below are my current settings for ONLY recording my screen, for instance for Chrome, no games.

Just recording the desktop, including shuffle some windows back and forth, will never give you the complexity a real movie has, so there is simply nothing to encode that increases the data rate. After all, it's a still image, even with you moving windows. Upscaling and recording material isn't also increasing visual detail and image complexity, so it's not suited for investigating encoder performance.

For tests, you need original and real video material. Sophistically rendering high detailed games are very good with generating real video material. Some kind of encoder benchmark (ok, not benchmark, more nightmare) is Rocket League or any racing simulation with highly detailed fast and continuously moving asphalt, grass and foliage.
