Hi,
I have
Ryzen 5 1600
16GB RAM 3200 Mhz
GTX 950 2GB MSI GAMING

Codec x264, veryfast, 3500 bitrate, profile high, interval 0, 1920x1080 with 30 fps, my streams in FIFA 18 (low quality) and Kingdom Come Devilarance are laggy and quality bluury... but game works fine, fps in game is 40-60.
I have network LTE, the cube are green, works fine on 3500 bitrate, any drops fps...

Sorry for my english, but im polish.
My examples streams on channel https://www.youtube.com/channel/UChk41KX6EUEH63dLOLH7hwA

Someone can help me fix that poor quality streams?

Ok i have new internet, pack 1TB for month, speed in speedtest.net is 70 Mbps.
Now i configure my obs with bitrate 5500, very fast, profile high, 1920x1080 with 60 fps, i stream desktop and game Forge of Empires in chrome, stream is blurry. Why?
Look: https://youtu.be/VfEudKGhHas?t=2253

15:21:16.258: Video stopped, number of skipped frames due to encoding lag: 18/289 (6.2%)

You're overloading your CPU.

https://obsproject.com/wiki/General-Performance-And-Encoding-Issues

15:21:10.645: [x264 encoder: 'recording_h264'] preset: faster
15:21:10.645: [x264 encoder: 'recording_h264'] profile: main
15:21:10.697: [x264 encoder: 'recording_h264'] settings:
15:21:10.697: rate_control: CBR
15:21:10.697: bitrate: 40000
15:21:10.697: buffer size: 40000

Don't use CBR for recording, it's mostly for streaming. Use CRF with a quality setting somewhere between 15 (really high) and 23 or so (not as high).

Also is there a reason why you set your buffer size to the same as your bitrate?

I would switch to simple output mode and choose between either "indistinguishable quality, large file size, or high quality, medium file size.

Then your logfile should contain a streaming session, not a recording session, in order to see if OBS is performing properly with your chosen settings. As it is you are overloading your GPU.
