The Witcher 2 Very Strange Performance Issue

I was running The Witcher 2 just fine yesterday on high settings, AA turned off and Ubersampling turned off. I was getting ~50 fps. I went to play it again today and I spawned into my save and am getting extreme lag (10 fps or less) along with really bad mouse + keyboard input lag (Corsair M65 and Corsair K70). I have not messed with any of my components or anything and the settings are the same as yesterday.
Specs:
CPU: i5-3570k (OC'd to 4 GHz)
GPU: Sapphire Radeon HD 7870 GHz OC Edition 2GB GDDR5
RAM: 8 GB 1600 MHz.

There must be a fix for this somehow.

How are your temps? A fan could have gone out/got bound up or something like that and something is throttling to save itself.

Both fans are running fine, I looked. My temps are at 17C idle, and got up to about 55C max. I tried a few other games now (Skyrim and BF4) and the same thing is now happening with them too. I'm beginning to think that they are choosing to use the Integrated graphics for some reason.

If your monitor is plugged in to your video card, I don't know that it's possible for it to use the integrated graphics, though I could be wrong there. I know it sounds stupid, but did you restart? There could be some process in the background causing issues or something, though that's a bit of a long shot.

I have restarted multiple times. I've just remember that yesterday when I went to adjust some overclocked settings for my 7870, MSI Afterburner wouldn't let me adjust voltages so I followed a guide where I had to change a few things in REGEDIT (something to do with enabling ULPS or something like that). I'm thinking that maybe that has affected it in someway. I have reverved the changes that I made in their now and reversed all GPU overclocks to stock etc. Is there a way to check your BIOS to see what GPU it is using?

Sometimes it will let you disable internal graphics, but like I said, as long as the monitor is plugged in to the dedicated GPU, I don't think you can use the integrated ones for anything but compute stuff like intel's quicksync video conversion and stuff like that.

Nothing is wrong with your system....this game cannot do more than 1366x768 res(even on my HD 5850)donno why.If you are using AA and ultra settings stick to 1366x768 or lower(1280x768 gave me the best performance)it will give you a stable playable fps of 30-50...

The issue is that he was getting better performance and now he's not getting that same performance any more. Also, no offense, but the 7870 is way faster than the 5850 at this point.
