Electrical issue causing input de-synchronization or input loss

Just going to kick up another thread similar to CrucialNUG's thread, will link if you weren't following at bottom. Still trying to gather evidence to help draw conclusions on the problem and to help truly resolve this type of issue, everything is pointing to issue with electrical flow or grounding impedance.

Circuit 1 (2 mins prior to the next video, game left running between etc)

Original File: https://www.dropbox.com/s/8oi5uxfby5...937AM.MOV?dl=0

Circuit 2 (Another circuit, just extension cord to transfer power to UPS to hallway)

Original File: https://www.dropbox.com/s/8b3cuog8mn...940AM.MOV?dl=0

Other details also in youtube video description
- No other load on either circuit confirmed via multimeter
- No windows or in-game settings were changed in-between these videos
- Using outlet in the computer room/office then outlet in hallway using brand new extension cable which passes continuity tests for each neutral, ground, phase.
- Putting the extension cord on the same outlet as office and running UPS through it, responsive experience stays.
- videos recorded with iphone, 720p 240fps slow-mo

All electrical systems connected to line interactive UPS to help reduce ground noise through shared path to ground
- router
- monitor
- computer

Other electrical related measurements to compare both outlets, both having same characteristics
- 0.00v neutral to ground when there is no load, otherwise 0.5v with ups connected 'on both' (see next video)
- Volts 117v, ground to hot
- Frequency 59.99-60hz, ground to hot
- Frequency 59.99-60hz, neutral to hot

CrucialNugs thread, currently locked but tons of other info in it related to this problem.
https://www.overclock.net/forum/375-...g-related.html

If you have any other suggestions for measurement or tests please post below otherwise I haven't been able to quantify any measurement in Windows that directly correlates to loss/delays. (xperf, windows performance analyzer, hwinfo64)

UPDATE:
Another video of Circuit 1 with my hand more visible in the video for comparison.

Maybe now all the people screaming placebo will stop whining in every thread about power issues. Good documentation as always.

"Accuracy and timing feels significantly de-synchronized."

How is this any different from the other thread? I'm looking at the OP, but I'm not finding links to the 240 FPS videos. Though 500+ FPS videos would be ideal.

If a bunch of words is now "good documentation," I guess science won't save us in the end.

Could be your script blocker if you're not seeing videos in my main post.

Thanks for the feedback, the original video is 720p I just checked. Will see why youtube didn't keep it that way.

Youtube is cutting video quality on their side of things at the moment. Noticed last night some of the videos from my favorites had suddenly gotten awful pixel-ly from one day to the next. :\

AFAIK it's due to the current crisis.

If you really find that diminished quality to be a problem you can always try one of the other video hosting platforms like Vimeo, or even a dropbox upload could be better than nothing at all. Otherwise there are always going to be platforms that refuse to make any changes so you could go with them.

This would be a good time for a niche youtube competitor to steal away viewers come to think of it.

Uploaded the original files to dropbox and updated the main post with links to each. Second video is a little out of focus but you can still see there is a difference between each.
