Question / Help Pixelated Blur during Motion

Hello everyone. I have been having this issue ever since I have started using OBS and I can not for the life of me figure out how to fix it. I have searched all over and could not find a definitive answer. I want to stream racing games and other high motion games as well as occasionally RTS based games. But no matter what game I play I always end up with the same quality problem.

Under Encoding I have done the following as part of each test I did.

Enabled and Disabled CBR
Changed Quality Balanced anywhere between 5-10
Enabled and Disabled CBR Padding
Enabled and Disabled Custom Buffer Size
Made sure Max Bitrate is correct so frames are not dropped
Left Audio Encoding as Default and have switched it to MP3 to see if any difference would be made

Under Video I have set the base resolution to 1280x720 (As this is what I want to stream at)
I have changed the filter to test each one.
I have changed the FPS anywhere from 30-48 (48 was maximum before frame dropping occurred)
And I have disabled and Enabled Aero

Under Audio I have left it as is.

And Advanced I currently have Multithreaded Optimizations Enabled
Process Priority Class is set to High
Scene Buffering is at 700
Disable encoding while previewing is disabled
Allow other modifiers on hotkeys is enabled
x264 CPU Present I have changed all the way between medium and very fast
x264 Encoding Profile is set to high
Keyframe Interval is set at 2
CFR is enabled
All other boxes in that section are left unchecked

You can see in the video what I am referring to. Image is good while I do not move but as soon as I move this insane amount of pixelation floods the screen.

Any help is appreciated.

well obviously that really high motion games start looking bad with 1800 bitrate at 720p@48fps i'd recommend 720p@30fps and try another preset like fast or maybe even medium you gotta monitor your cpu usage while playing and streaming.

or even downscale more im sure racing games do look still decent at 540p could even go with 540p@48fps

else you gotta live with quality loss while streaming thats the way it works

Quality, high frame rate, low bitrate.
Choose 2.

Quality and High Frame Rate

EDIT: I was also able to set my bitrate to 3500 and its still stable. Yet the quality has not changed a bit :/

http://www.twitch.tv/nordiiq/b/483606716 set @ 3500

Double EDIT: I have the following settings put right now and I am not dropping any frames or having any lag so I have reason to believe its stable.

Am I doing something wrong?

I'm not sure if this will work but try setting a bigger or smaller buffer size with a quality 8 or less. If you use 2000 bit rate set it to 1000 and 4000 and see if that changes something.
And use veryfast encoding on advanced settings btw...

What you are trying to stream is practically the worst case scenario.
If you are not happy with the results you can only further increase the bitrate(not recommended), lower the resolution or lower the frame rate(recommended).
