GTX 760 Underperforming - Bad FPS

[JordanNguyen]

I have an EVGA GeForce GTX 760 SuperClocked and was expecting to be able to run Skyrim at Max settings on 1080p with at least a constant 60 FPS. However, when running it at Max I get only 10-15 fps which makes it pretty much unplayable. On high settings it gets around 10-20 FPS. The only way I can play it is if I turn the settings down to medium or play on 720p, when I thought the 760 was capable of much more. Also beat Sleeping Dogs and had to play it at 720p on medium settings because the video was just too choppy. I did some research and it seems I'm not getting anywhere near as much performance as I should be. Any ideas?

My Specs:
Intel Core i7 4770k @ 3.50GHz
EVGA GeForce GTX 760 SuperClocked w/EVGA ACX Cooler 2GB
Gigabyte GA-Z87X-D3H Motherboard
16.00 GB DDR3 1600MHz Corsair Vengeance
Seasonic 750W PSU
27" Asus Monitor
Windows 8.1

I've updated all Graphics card drivers. I used Display Driver Uninstaller to remove all GPU drivers so I could reinstall them.
Are there specific drivers for other components I could have overlooked or is my card just faulty?

Uninstall in safe mode with 3rd party software. This is more inclined t o AMD driver issues, however somme folks have reported good results with nvidia cards.

There are motherboard drivers you should install, but I don't think this is how problems with that would manifest. A driver problem of some sort seems more likely. You should definitely be getting much better performance.

Could be faulty. You should be getting a solid 60fps on skyrim at 1080p on max settings, even with the basic high res pack.

Also, check temps and ultization of both CPU and GPU in game, incase one is throttling.

Thanks guys, I tried your advice but no go. Nothing seemed to fix it so I went with the safest way and did a clean install of Windows 8.1. Reinstalled drivers and now it's working fine. I don't know what I did wrong the first time but; albeit a slight setback, I'm good to go.
