Hi, I recently managed OBS Studio for windows and I realized that the videos that I recorded or made streaming the moments where there is a lot of movement the image looks grainy and lose a lot of quality.
I do not know if I have done the configuration well because I managed by the tutorials of youtube and I think that to have well configured OBS each PC has an optimal configuration.
I leave this video for you to see what I mean, when the image is stopped looks great but when the character moves and picks up speed, the quality of the image looks pretty bad and blurred.

This is my PC, I guess I meet the requirements:

CPU: Intel Core i7-6700K BOX CPU
BOARD: Gigabyte Z170X-Gaming 5
SSD: Samsung SM951-NVMe 256GB Lec: 2150 MB / s Esc: 1550 MB / s - SSD Disk M.2
HDD: Toshiba DT01ACA200 - 2TB - 3.5 "- 7200rpm - SATA3
BOX: NZXT H440 V2 Black / Red
Font: Corsair RMX Series RMX650 80 Plus Gold 650W Modular - PSU / Source
RAM: Corsair Dominator Platinum Series 16GB (2x 8GB) 3200Mhz PC4-25600 CL16 - DDR4 Memory
GPU: Gigabyte GeForce GTX 980Ti Xtreme Gaming 6GB GDDR5
Cooler: Cooler Master V8GTS V2

My conection 300mb download and 314mb upload

What should I modify from the configuration to fix it?
Thanks for your time.

1920x1080p @60FPS needs 3500 kbps bitrate

Instead NVENC, try using x264 (CPU encoding)
With same options, you will get better image.

If it lags, return back to NVENC

You current bitrate of 2500 isn't enough for 1080p @ 60fps even with 3500 bitrate its not enough for 1920x1080p @ 60fps you need to change this to 1920x1080 @30fps if playing low motion games, If that's still not looking great 720p 30fps. [Ensure you are using CBR]

There should be no need to use Nvenc here for streaming the 6700k can run 720p @30fps on a veryfast preset even @ 60fps no problem. If you are playing high motion games stick to 720p but if low motion like RTS you should be ok with 1920x1080 @ 30fps using a bitrate of 3500.

If you want to record then use Nvenc with 1920x1080 @ the fps you are streaming, set it to VBR and a bitrate of 40k or use CBF = 23 depending which you prefer and tweak as required.
