EXTREMELY Low FPS in Fallout 3

How can I explain this? I literally just turned my computer on one day, launched Fallout 3, and got (not kidding) <10 FPS (main screen and in game). This is an obvious glitch. There is also an occasional screeching sound in the audio in the game.

System:

i7 3820
16GB DDR3 RAM
GTX 690

Things I've tried:

- uninstalling and reinstalling
- removing all mods
- 4 core fix
- making it run on only one GPU instead of SLI
- downgrading AND upgrading drivers
- everything


This literally happened overnight.... No idea what the deal is. If someone could help, I'd be so happy. Thank you all very much!

This is usually caused by the computer resetting some settings following a crash or improper shutdown. Check your BIOS if it's in power saving mode or if it has changed some of your CPU / PCI-E lane settings. I've heard that there's also some kind of a 'slow-mode' on the GTX 690 itself, no idea how this is toggled though. It could be through the Nvidia driver software or there could be a physical switch on the card itself.

While you're inside the case, do check that everything is seated properly and everything is connected as it should be.

Also load some monitoring programs and check your CPU and GPU temps. Make sure your CPU fan is firmly mounted and your case is dust free.

Does that only happen with that particular game?

Thank you so much for all the replies, folks.. And yes, this is the only game where it happens.

Went into BIOS and everything seemed to be adequate.. :(

I would check your settings in the nvidia control panel and perhaps reset them to defaults just in case something is being forced through the control panel into the game.

Did you uninstall the game and the drivers?

Do you use onboard sound or a pci card for sound? Perhaps you are having some sort of conflict (not sure what to be honest). Try disabling sound completely for the whole system and run the game.

Again, thank you for the responses. I'm reinstalling it as we speak. I completely wiped it. I also tried an entire array of different NVIDIA drivers from different times.

Hello, folks. As for an update, I COMPLETELY nuked the game off my hard drive again AND disabled sound (mic included) and no luck. What the heck is going on? Thank you all for your responses... I hope someone finds it out.

Well for a bit more extreme measure you could always format your computer and start over again. Maybe that might restore your game to its glory.

Excellent idea. I'm completely re-formatting my comp with XP. Will report back when done!

Maybe give xl2aNd0m's idea first crack. Couldn't hurt and might save you a bit of hassle.
