Blurriness during gameplay

Hello.
I'm encountering issues when Live-streaming to Twitch. My Gameplay get's very blurry and pixelated when I'm panning my camera or moving around the game world. My surroundings turn to some mushy blurry textures and it just looks awful on stream.
When I'm standing still the game looks just fine and crisp.
I've googled and run various different tests and settings that people suggest but I can't find anything that smoothens it out.
Changing the bit-rate to anything between 6000-8000 Kbps doesn't seem to do anything for me. Also tried different Output (scaled) Resolution both with Bicubic and Lanczos. As well as the Presets from P5-P7.

Running the wizard tells me I should stream my base canvas resolution which is 2560x1440 to Output Resolution 1920x1080
Video Bitrate 6000
NVENC. H.264
High Quality
60 FPS
- I'm doing this except I've cranked it up to 8000bitrate and used to override streaming service recommendation. Honestly, doesn't seem to make a diff.
My monitor's refresh rate is usually 144 hz and that's where I game at - I saw some post about locking it down to 120 instead. I tried that and it didn't make any difference.

Here is a video of my recording which shows my issue

Here is the log from that stream session.

Looking at the log myself I found this:
05:41:30.070: Failed to get NVVideoEffects.dll version info size
05:41:30.071: [NVIDIA VIDEO FX]: FX disabled, redistributable not found or could not be loaded.


There's also some other "Failed to get" or plainly "Failed" but I'm not really good at understanding it all so would be grateful for any help here.
Thank you

Don't try to show what video quality looks like using YouTube. It works completely differently than twitch.
You can go to the Rust game category on twitch and see what image quality people stream there).

Well I guess only I can say that the video on youtube does look the same when I watch it live and shows the blurry stuff I have.
I'm gonna give it a go with the settings mentioned in that post by you and see if it helps.

What is key is the bitrate, resolution and frame rate. Try to become an affiliate streamer as soon as possible to safely use the 8200 kbps bitrate. The lower the resolution -> better quality (not relevant for YouTube), but worse picture clarity. Lower frame rate of the stream -> better quality, but worse smoothness.

Manipulating resolution and frame rate simply allows you to save bitrate. B-frames are also useful for this, but it's best to leave them at their default of 2.

This year we will hopefully have av1 support on twitch so that will really help improve the quality.
