For a week or two showing video on my Raspi 5 with NVME is impossible. The framerate is now something like 2-3 seconds per frame.
Before the axe fell it went smooth, Youtube video, TV, videos in news sites, no problem at all. The problem exists no matter if the connection is via wifi or ethernet.
I have tested up- and download speed with Speeedtest.net. The results are 50 to 52 Mb/s, and the connection is specified for 50/50 up and down.

I would look at what is running on the Pi. Use htop to see what processes are using CPU. It will also show total memory used and if there is any swap usage - which will kill the machines performance.

Browsing is a memory hog. Have you tried immediately after rebooting and before running any browser? What does the output of 'free' show?

I have used some test from Tom's hardware, using vcgencmd, as shown at the bottom.

I suspect it isn't anything hardware or power related as you would get some outright failures rather just slowness.

There has been several updates coming in to the Raspi lately. I check what is in the updates but often have no clue to what is does, and just let it install. But if an update causes havoc like this, other people would have been hit, and it probably would have been mentioned in this newsgroup.

It's always a good idea to do a backup before a major update, put that on an SD card and see if the problem is with the older software.
It maybe something has been reconfigured such as going from Xorg to Wayland display systems which your video playing app doesn't work optimally with.
