So I recently got the GIGABYTE Radeon RX 570 and for the first week, everything was running fine in games with 250+ fps in most games, but after that my fps would just drop on its own(250+ fps to 100-140 or lower), so I tried restarting my PC and by doing so, my fps only got worse and would only hover around 80-140, the only fix I had found for this was to reinstall my drivers, but every time I would restart my PC the fps would drop same as before and I would need to reinstall the drivers all over again, any ideas? (Note; I have not touched anything in the control panel either; global wattman or anything else etc.)
SYSTEM:
BTW not sure if its a driver problem or something, so the thread in the Drivers & Software forum
