Stream gets pixelated on 20000 or more bitrate

[DPMJ]

Hi,

Fiber connection
The internet upload speed = 86.78 Mbps and there has never been any dropped frames on my streams.
The download speed = 89.57Mbps

OBS Studio = 27.2.4, 64-bit,
OS= Windows 11 Pro
My CPU = i7 9750H 9th Gen, Base speed: 2,59, Sockets: Cores: 6, Logical Processors 12
My Gpu 0 = Intel UHD Graphics 630
My Gpu 1 = Nvidia Quadro T1000
My Ram = 32 GB

I want to stream 1920x1080, 60fps witouth pixelation should be doable right?

Here are some screenshots with my current settings for streaming.

Which GPU is OBS running on? Be aware that NVENC on the 600-series (what few of them supported it) was absolutely awful quality, and using Veryfast x264 (CPU-based encoding) will give better quality with minimal additional CPU load.

Thanks,
OBS is running on Nvidia Quadro T1000.
My video card is Nvidia Quadro T1000 and is supported.

All good, just making sure. Yep, it's part of the official Support Matrix. I'd have to ask why you're running the 630 at all? Need more than four monitors? Splitting the primary PCIe lanes like that to x8/x8 is going to decrease your performance, compared to giving the T1000 the full x16 lanes. It could improve overall performance to remove the 630 from the system.

Past that, we'd need to see a logfile from a streaming session where the pixelation issue is occurring to check for other possible root causes. 20mbps SHOULD be enough (especially with a Turing NVENC core), unless you're streaming something with lots of fast motion and/or heavy foliage. YouTube's re-encoding also can play less-than-nicely, but 20mbps SHOULD really counter at least most of that.
