I don't know why my GPU is throttling now. I haven't done much. It does it in all my games. The throttle happens when the game renders everything i'm about to see . U know how like you close a door and some advanced games minimize rendering behind those close doors, then you open the door and it renders everything in the room.
Ok I lied, I've been trying to fix this problem so I did a lot of things to my PC before I started noticing this. i was literally trying to fix my instability issue, but I'm starting to narrow it down to gpu, psu, or mobo. Could an underperforming ssd cause this? My ssd right now is only writing at half speed. I'm about to try and hopefully fix that by doing a "secure erase" and then reinstalling the OS on it.
P.S. My gfx card is a Sapphire Nitro R9 390 and it's at constant 70 degrees under load.
