Looking for best quality on the stream

This is my first post on this forum, so I just want to say Hello everyone !

In the past, I have already streamed my gameplay with the help of OBS on a much weaker computer compared to what I have now, but the quality of my stream is (in my opinion) unsatisfactory, especially that I find channels where players often have weaker hardware, and their stream despite everything looks better than mine.
Mainly I'm streaming World Of Tanks and occasionally Path of Exile.
I`m looking for best possible settings for my NEW PC:
MOBO: ASUS Prime Z390M-Plus
RAM: Corsair CMK16GX4M2B3200C16 Vengeance LPX 16 GB (2 x 8 GB)
CPU: Intel Core i9-9900K
GPU: PNY GeForce GTX 1660 Super 6GB
Screens: AOC Gaming Q27G2U (main) / iiyama X2783HSU-B3

Ingame resolution: 2560x1440 in OBS scaled to 1920x1080

Compare to my OLD PC:
MOBO: ASROCK H81M-ITX WIFI H81
RAM: HYPERX FURY BLUE HX318C10F/8 (2x DDR3 8GB PC16000 1866MHZ )
CPU: INTEL CORE I5 4460
GPU: GIGABYTE GTX 960 4GB
Screen: iiyama X2783HSU-B3

As you can see, the processor is much more powerful, a better graphics card and a second monitor, and there is no difference in the quality of the stream, I would even say that on the old computer the stream was more stable.

I was streaming on my old computer via NVIDIA NVENC H.264 (new) due to weak CPU.
On the new PC, I also tried streaming with NVIDIA NVENC H.264 (new) settings at the beginning, but felt a slight lag and "jumping" while playing and noticed a drop in stream quality, so now I'm streaming on x264 but still not happy with my streams .

There's no recording attempt in those logs, so we can't see any necessary details for encoding settings or missing frames. Make sure to do a recording test, then upload the logs.

From what is there though, make sure you're running OBS as admin. That adds OBS to the GPU priority list and helps to prevent rendering lag.

Each time.

There's a fairly easy way to ensure this though. Pin OBS to your taskbar, then right-click on the icon, right-click on OBS, go to properties. Click Advanced... and check "Run as administrator". This will ensure it is run as administrator any time you launch from the taskbar icon.

There's still no results from those logs, as it's taken before the stream is closed. There's only the stream settings, so we can't see where the frames are being lost.

However, based on what is visible...
Code: 
10:20:53.158: [jim-nvenc: 'streaming_h264'] scaling enabled, falling back to ffmpeg
10:20:53.158: ---------------------------------
10:20:53.158: [NVENC encoder: 'streaming_h264'] settings:
10:20:53.158:     rate_control: CBR
10:20:53.158:     bitrate:      5750
10:20:53.158:     cqp:          0
10:20:53.158:     keyint:       120
10:20:53.158:     preset:       hq
10:20:53.158:     profile:      high
10:20:53.158:     width:        1920
10:20:53.158:     height:       1080
10:20:53.158:     2-pass:       true
10:20:53.158:     b-frames:     2
10:20:53.158:     GPU:          0
OBS is reverting back to the old NVenc because you have "rescale output" selected in the output. This should generally only be used if you're recording at one resolution and streaming at another resolution. This method forces the rescaling to be performed on the CPU, and also requires the framebuffer to be sent from the GPU to the CPU, and then back to the GPU for encoding (which is why the new NVenc method cannot be used).

Instead, set your Output (scaled) resolution as required in your Video settings tab, and uncheck "rescale output" in the Output settings tab.

Other things to ensure for the NVenc settings:
- Do not use Max Quality
- Uncheck Lookahead and Psychovisual Tuning

These options all use CUDA, which can cause issues.

Make those changes, and do another streaming test. Make sure to close the stream and upload the current OBS log while OBS is still open. That should give the necessary information needed.

MS Defender may use less resources than some other AV solutions (not all), but it also does less than some of them.
So... choose wisely
