Title says it all, save for details.
After trying to play some heavy-hitter games I haven't tried in a while, specifically Crysis 2, I found I'd run into a drastic dip in performance that seemed wildly inappropriate given my system specs. And I know it's Crysis, yes, but I also knew I'd played the game before at FAR higher settings, and only started lagging with the high-res texture pack enabled. My playthrough under similar conditions yielded between 2 and 8 frames per second in the submarine intro sequence. And yes, I've tried other things like the 3DMark DX11 benchmark tests, and those ran even worse than Crysis did.
A major thing I realizes was that my CPU was clocking in at lower than half speeds, but I fixed that after realizing for some bizarre reason the computer was set to a power-saver mode that demolished my clock speeds. Setting that to performance mode fixed that.
I was still having almost NO better luck in performance though, so I tried the Furmark test (and yes, I know people don't recommend that one anymore) and found my GPU was throttling at less than 10% its regular core clock speed.
However, I still had GPU Shark running, and learned that Furmark tends to make modern GPU's auto-throttle under the abuse it throws at cards, I instead I did my own stress test by running Crysis 2 in an 600x800 window at highest settings. This yeilded roughly 15-20 frames per second, in case you're wondering.
What I found however was that my card WAS indeed throttling the shit out of its performance.
In it's low-power state, the 570 is set to a core speed of 50MHz, a mem speed of 135MHz with a VDDC of 0.913V
At it's high performance state, it's set to clock the core to 770MHz, mem speed 2000MHz with a VDDC of 0.988V
Under the load of both the Furmark and my Crysis 2 test, it topped out at a core clock of 66MHz, mem speed of 324MHz with a VDDC of 0.988V
So I know the voltage is set properly when the GPU demand cranks up, but the card is stopping itself at roughly 9-16% of it's overall capability.
Why? This is the question I pose Facepunch, because frankly I'm amazed I followed the rabbit-hole THIS far.
The only options I can come up with for why this shit is happening are:
A: The card was defective, finally cracked and needs to be replaced (in which case I'm glad my 460 is still floating around here)
B: I'm a dumbass and accidentally flicked a switch in the NVidia Control Panel that's demolished my graphics performance.
C: Something has become of my 750W Corsair PSU, and the card is clocking itself down to account for a lack of available power.
And you might ask me if the throttling is due to overheating or something, but believe me when I tell you it isn't. See, I got the MSI Twin FROZR version, and this sumbitch' under load isn't breaching 50 Celsius. I'd imagine the throttle would kick in a LOT farther than that if it was getting too hot.

Oh, also I'm hearing I should watch the +12V voltage to see if it lowers below 11.4V. Just tried my Crysis 2 test again with Speedfan open so I could pay close attention. Never went below 11.99V. So, I'm not particularly knowledgeable, but that makes it sound like the card should have plenty of power to use, or so logic tells me.
Well, here's an update... not that anyone seems to care (yeah, thanks guys...)
I heard that doing a clean install of the driver might work, and after doing so atop several reboots later, my GPU was back to full speed and dominating Crysis 2 at 60 frames per second easy on max settings.
But of course, a few hours later after playing TF2 with my brother (and getting like 200 frames per second out of the game) I come back to see GPU Shark, and the core clock is registering... you guessed it... 66Mhz no matter WHAT again. I have NO idea what triggered it to do this or why now.
Seriously, what the fuck?! It's not short on power, it's not even CLOSE to overheating, the driver is clean and up to date, and it seems perfectly capable of delivering its blistering performance.
The Hell is going on, and how do I STOP it?!
Please, somebody help me, or at least fucking ACKNOWLEDGE that this thread exists, because I hate sitting here while fucking NOBODY says a goddamn thing.
Just now noticed this thread exsisted, calm down bro. Some threads are posted at awkward moments and nobody notices. I'd RMA the card or just wait until someone here finds a solution.
Check your power settings in control panel.
Try using MSI Afterburner if you don't already, see if that helps anything.
Alright, well, discovered that the thing apparently resets whenever I reboot my machine. Went through the 3DMark11 trial with flying colors after that. No idea what's triggering the throttle though.

If it comes to that, I've got my old 460 floating around here somewhere.

Already did the power settings to get my CPU back up to speed. The PCI-E options are off, which I'm told is how they should be, so I don't think the problem lies there.
I'm intrigued by what you mean by "using" Afterburner though. Use it how? I have it, and indeed checked it for any way of fixing the problem, but never found anything obvious. If you're talking about the clock settings and such, I've never touched them as I know nothing about how to overclock stuff and am afraid I'll kill my computer somehow by messing with it. I always ran my stuff stock, unless it CAME superclocked or something.
Oh, and thanks for the "dumb" rating. Appreciate it.

You got the dumb because of your lack of patience.
Set the stock clocks in afterburner and check "apply overclocking at system startup" even though you aren't overclocking it. Then apply the settings and play, see if that keeps the clocks stable.

If you are already using afterburner like that then I'd just RMA it, it seems like you've tried everything you can.
