Very poor performance in most games

Hey guys, I've been using dolphin for years and I truly appreciate all the hard work that goes into it. I've been having a blast replaying old games and games I haven't played before in HD. This is my first time posting in the forum, though.

Before anyone says anything, I know I have an AMD processor. I've heard so many people say they're absolute dumpster fire for emulation. However, I've been playing games at full speed with my FX-8370 clocked to 4.3 GHZ.

My current setup:
CPU: AMD FX-8370 at 4.3ghz
RAM: G.SKILL Ripjaws 16gb
GFX: NVIDIA GTX 1070
and NVIDIA GTX 650 ti Boost for a third monitor
The fan is dead on my 650 but it doesn't warm up further than 40 C because it's just displaying the desktop

About two days ago I updated my graphics driver to 388.31 and started having terrible performance in Arkham Knight. No surprise there, the game is horribly buggy so I just wrote it off. The next day, my screen suddenly went black and came back on. I wasn't playing any games so I checked my graphics cards temps and saw that my 650 with the dead fan was at 86 C! It was running at 900 something mhz instead of the usual 324. This has happened to me before so I ran DDU on my graphics driver and installed an older driver, 388.00. My graphics cards are no longer constantly under load but I'm getting terrible performance on dolphin now. Brawl is stuttering a lot, sonic adventure 2 runs at a constant 53 fps, and sonic colors can't get past 30 fps with the 60fps hack. It stutters a lot even with the hack removed.

It seems like it's not a problem with dolphin itself but if you guys have any suggestions I would be very grateful.

It's true, you have a dumpster fire of a CPU, but that dumpster fire is clocked high enough that it should honestly be ok for a handful of games, Brawl should absolutely run at full speed.

Check to see if your driver is forcing v-sync or getting clock down in low powered mode.

Yeah, it really sounds like for whatever reason the new drivers are using the 650ti for all rendering - have you tried (temporarily) removing that to see if it fixes things?

Also - not having the fan is pretty dangerous - "unexpected" things can cause extra gpu load - even on "Desktop" use (composition, video acceleration, browser canvas acceleration etc.)

I disabled vsync on the nvidia control panel.
My card isn't getting underclocked. It actually goes up for no reason just sitting at the desktop. I have it set to optimal power mode. I tried maximum performance but it didn't help.

Removing my 650 didn't help either (´⌒`。)
