I recently upgraded my PC and I'm getting extremely poor performance from the 660ti I bought a while back. Here are the specs:
Mobo: MSI Z87-G45
CPU: Core i5-4670K @ 3.40GHz
Video: EVGA GeForce GTX 660Ti 3072MB GDDR5
PSU: PC Power and Cooling S75QB Silencer 750W Quad Power Supply
RAM: 8GB DDR3
I took a look at a TH review of the 660ti with benchmarks for games like Skyrim: http://www.tomshardware.com/reviews/geforce-gtx-660-ti-benchmark-review,3279-9.html
Admittedly the CPU tested is better than mine, but that doesn't seem to be the issue here. Where that tester was getting an average of 80fps on Ultra settings, I get somewhere around 15fps on Ultra. That's a massive difference. I lowered a bunch of settings but it still isn't making up that much of a difference.
I decided to run a performance monitor to check on things. What it shows is that when my GPU runs at 99% capacity (which is pretty much anytime in-game) then framerate gets hammered. Anything below that and the gains are immediate. Here's the image I took of that while running on high settings at 1680x1050:
20fps or so is totally unacceptable for this card on an unmodded Skyrim if you ask me.
I decided to test against some other games. All terrible.
Dishonored runs at 20fps at 1920x1200.
DOTA2 runs at 24fps at 1920x1200. Runs at around 35-40fps at 1280x800.
I ran GPU-Z and here's the results:
For some reason my card is running at x8 1.1 instead of x16 3.0. I don't know if that's the reason for the poor performance or not. And before you get to it -- yes, I tried the render test under the "?" and it had absolutely no impact. I also ran 3dmark and it didn't have any impact on the Bus Interface. Speaking of which, here's the 3dmark results: http://i.imgur.com/yuCIoag.png
I feel like I've tried everything. I reset the BIOS, updated to the latest drivers, tried older drivers, tried reseating the video card, tried using a different slot (it got me running at x1 1.1 instead of x8... even worse!) and so on. Nothing works.
I could really use some help!
