Old video adapters cannot to play more than 30 frames per second videos

I use Ubuntu-Studio 20.04.3 LTS inside two desktop computers and one laptop computer.

That laptop is a HP 250 G5 device, which we can consider as an old computer.

The internal video adapter of that laptop isn't capable to play UHD videos with more than 30 frames per second.

I tested it with the same video, same resolution, same format file, but 29.97 fps and 50 fps. The 29.97 fps version is played "satisfactorily". I mean, we can see it (some stuttering, but not to ugly). The 50 fps version... Not comment. Simply: TOO BAD!

Of course, the right solution is to get a new device.

But... I wonder if there is some way to work around this, in the old device.

Some idea? ???
