6000 bitrate is not high enough for high quality, high motion content at 1080p60.
1080p @60 fps

- Resolution: 1920x1080
- Video Bitrate Range: 4,500-9,000 Kbps
Choose between 720 or 900p60 or 1080p30 or go to 8000-9000.
Depending on the content, you will always find pixelated/blurry frames, even with 720p 60fps 5200kbit/s (even with x264 slow preset).
You can try 720p 60fps 9000kbit/s. This should give a decent image 90% of the time (still depends on the content).
Less details and movement will save bitrate / quality. So even with the same OBS setting, you will get less pixelation, when you increase ingame antialiasing and reduce texture resolution, add motion blur etc. The less details, contrast, sharpness and the less movement, the better it can be compressed.
