Graphics card suddenly very bad?

has been going extremely bad for 1 to 2 weeks no game is smooth even though I have over 60 fps. For example, Minecraft is over 100 and it still jerky.

I don't know why but my old graphics card, the gtx 560 ti runs better than the Rx570 which shouldn't be

What about the temperatures?

I have an RX 580 and also occasional performance problems despite the high number of FPS. I suspect that my switch from Nvidia or the somewhat strange connection as eGPU (via M.2 PCIe) is to blame. But if you have similar problems… Did you install all drivers?

Driver problem from the last windoof update maybe. Download the latest GraKa driver from the manufacturer and install it.

So they are not too high, never comes over 80

You should first download MSi Afterburner and then view the load and the temperatures of the respective components.

Did you update the driver?

Yes I have the latest drivers

So the 20.2.1 from 30.01.2020?

Yes, they checked yesterday or the day before yesterday
