With constant loading on the video card, it resets the hertz for no reason, what should I do?

Question

Video cards

The video card works stably until the time when the load does not reach 100%, then it resets the frequencies. From the temperature everything is stable at 75 degrees, the manufacturer's website says that throttling starts at 85 degrees, and the maximum temperature is 100 degrees, so overheating disappears, it is very it looks like some kind of throttling (due to overload), but I don’t know others besides thermal throttling, I hope that you rummage a little more about what the video card wants from me.
Ps: I have a mx250 mobile graphics card

Answer 1

Well, yes, you have a mobile video card. The laptop manufacturer, based on the capabilities of the installed cooling system, sets the throttling parameters. 75 degrees for the laptop counted a lot, there, in addition to the video card, there is also a percentage nearby.
