Question / Help Stream Blurry

Let me get straight to the issue!
My PC components:
i7 7700k @4.2ghz
1060 6gb dual oc asus
z270k asus prime
16gb hyperx predator @2400mhz
My internet is 120 DL / 15 UP
OBS settings are from log: https://obsproject.com/logs/vba2Am1hlHr21Cwg
Basically 720p/ 5k bitrate/ x264 encoder/ very fast preset/ keyframe interval 2/ ofc CBR/ Lanczos Filtering
On high motion games, with a lot of movement involved my stream looks super blurry and it's really bugging me since there are no dropped frames, if there were dropped frames I'd understand...
Even tho it's CBR still my bitrate is super spiking and it's really confusing me, I used the Twitch Test tool and got quality 100 on 10sec tests, should I be testing for more?
Anything else I can include, let me know...

Please post a log with a streaming or recording session.

Restart OBS, start a session for, at least, >30 seconds, preferably in the same conditions that led to the issue posted then stop streaming or recording session and upload current logfile.

Your log doesn't show anything that could cause any issue. If you're streaming a high motion game, it's most likely due to needing more bitrate to improve quality and/or needing to use slower CPU presets. If I recall correctly, you need, at least 5500kbps bitrate for 720p@60FPS and mid/high motion scenes.

I do see other misconfigured settings unrelated to the topic but I'll only mention them if you just want to prevent future visits to the forums.

That'd be ideal kind sir, thank you very much, anything you saw that should be tweaked I will modify for the sake of not visiting anymore haha.
Also could it be my ISP's fault? As I previously mentioned even tho I am set to CBR @5k bitrate my bitrate is going to low 4,029 kbps and up to high 5,736 kbps according to Twitch Inspector, is this normal behaviour? I do not have Optics of course to achive extreme stability but is this normal? I do not drop frames, but it does spike a lot.
I apologize for the disturbance and thank you very much for your help.

Upload rates are never perfectly stable, it's normal to have some variation, even when using CBR, it's part of the reason media websites have buffering, to account for said variations.

Let's go by parts:

1) Run OBS as administrator;

2) Change YUV Colour Space to 709;

3) Instead of "Display capture", use "Game capture", as it is more efficient;

4) Unless you plan to fullscreen your camera, drop the resolution to 640x480p or 480×360p, since a small camera frame on the corner is wasting the extra resources required to run 1280x720p;

5) Use the following guide to improve your audio: https://obsproject.com/forum/resources/obs-studio-enable-coreaudio-aac-encoder-windows.220/

6) I'd really recommend using NVENC (new) for encoding, as it is significantly more efficient and has similar quality to x264@very fast, thus freeing up CPU resources for everything else running, like your game. CBR, "Quality" preset, disable "lookahead" and "Psycho Visual Tuning".

I'll edit this post if I remember anything else.

I want to make sure for something tho, is Game Capture a must? Since I really feel comfortable with Display Capture, I've also tested my PC performance wise, I get around 55ish celsius and up to 50-60% usage while Gaming and Streaming, I do have a lot higher usage on the GPU in games such as Skyrim for an instance, am I still okay using x264? Since I didn't feel any impact at all on my Game Performance, I apologize for further disturbance.

It's highly recommended, "Display capture" is only used to capture the desktop or when the game or software in question can't be captured in any other way. Also, as long as you have a "Display capture" source added, even if it's inactive, Windows 10 forces their own implementation of VSYNC on your applications.

You're ok using x264, it was merely a suggestion to free up resources for no real penalty.

Thank you, what color range should I use for 709 Color Space btw?
