Hello everyone.

I have a little problem with my friends gpu. That is an R9 390. So the error is the following. Yesterday we update his OS from Windows 8.1 to 10. Everything was fine but when he started to play some games, the gpu usage start jumping and ingame his fps drop from ~80 to 10-20 every 30 seconds. Everything is fine with videos even high quality Ones, but in games its looks like slow motion. Not just lagging or freeze. We tried everything, change os, drivers, cleaning, but dont ehat cause these errors. Temperature is fine, vents are working but when it happens the vent are going loud for a few sec.

Thank you for every answer 😉
