How to remove lags when watching 4K 60fps video shot on Go - pro 9?

Question

Video

Hello everybody.
When recording video on Go - pro 9, and then transferring it to a PC (Win10), there are brakes and lags, audio and video out of sync, lag, and so on. These artifacts appear in the standard viewer (Movie and TV, and in the windows media player).
When viewed on the camera itself, everything is clear and without lags, smoothly. By the way, 2.7K videos look fine on a PC, without lags, but the smaller 1440p at 4:3 slows down again, and 5K is good again. The corresponding memory card (PNY from the Elite-x series, 64 GB. 10 class). HEVC gadget for win10 installed. K-lite kodek is also available. I tried to open it with various players, only one KM-player pulls out normally.
PC configuration should be more than enough for this: Ryzen 7 3700, 32 gb RAM, GTX970.
The question is that video opens in KM-player, okay, the PC config also meets the requirements, but there is clearly some kind of purely software crap. Something is missing... Thank you all for your replies.

Answer 1

Nobody uses the built-in player in Windows.
Try vlc player
Well, you are watching from a PC disk, not from a map?

Answer 2

4k and 8k at 60fps are extreme video parameters and require hardware support and specific software. Very few players are able to play this on universal hardware (pc gpu).
Windows media player is the worst media player in the world, both in terms of functionality, usability and performance. I thought everything was more than completely scored on him.

only one KM-player draws normally

Well then what are the problems?
with the installed k-light codec pack, media player classic should also be installed, does it really lag in it too? I always recommend everyone on windows only it is the best player.
Also (on linux) I got the best results from ffmpeg (more precisely, its ffplay utility) I watched 8k videos and more with different fps on a rather weak machine.
ps the most functional and efficient player comes with a browser, only in it I launched 8k playback (I don’t remember exactly how many pixels there were, it’s huge) in repeat mode, and only html video does it without a pause

Drno Could this be related to the memory card? on my reading speed | the entries are: www.pny.eu/ru/consumer/explore-all-products/micros... .
And in the video where the bitrate is above 100 megabytes, the brakes begin.
