1080Ti Underperforming Horribly

[Daxyehn]

I upgraded to a GTX 1080Ti recently, but its performance is well below any benchmarks that I have seen. An example of my problems: On skyrim in whiterun while looking at the town on 4k, it has lots of lag and is around 25-35 fps, but when I look at the sky it shoots straight up to 60. In Dead rising 3 unlocked frame rate, it is at 60 while I'm inside buildings and 25-30 while outside. ME:A started okish, but was more around 30 most of the time until I reached the second planet and barely gets above 20.
PC Specs
CPU: i7-6700
MB:mSi Z170A
Memory: 16gb DDR4
Video Card: EVGA GTX 1080Ti
700w PSU

All my drivers are updated. I changed all of the power options in nvidia to be maximum and erased all of the old drivers. Whatever advice yall have would be greatly appreciated. Checked on afterburner and GPU was running at 100%

Use DDU to fully uninstall your previous drivers. Use it in safe mode and then reinstall the drivers from the nvidia site.

Please write the make and model of your PSU. If you are not sure, look inside your case.

My PSU is a coolmax zx-700
I used ddu to uninstall and then reinstalled, and it didnt work

That PSU is total and utter crap. Coolmax is notorious for their horrible PSUs. Some even exploded while testing.

For a 1080ti you should ONLY use a high quality and well built PSU. Buy a new PSU of at least tier 2 from the following list:

If you can afford a 1080ti, you can afford a decent PSU.

I will do that. When I built the pc, it was with a friend who had a lot more experience and so I just deferred to him on the psu without doing research. I am going to be leaving for a week, but will buy a new one when I get back. I'll let you know how it goes.

Grab an EVGA G2 or above unit. They use Superflower as the OEM. Plus EVGAs customer service is insanely good.

^ I second the EVGA suggestion, good PSU's.

I got the EVGA G2 750 watt and got it all hooked up. Im having the same problems as before. What should I try next?

 

[trawetSluaP]

Hmm, so you did a clean install of drivers? Have you tried removing and reseating the GPU? Also have you tried running benchmarking software like Unigine Heaven to see how it runs?

Yes and yes. I ran Heaven 4 again to see my score compared to others. Ive seen others without an OC'd card get a 3500 score
FPS:50.9
Score:1283
Min FPS:6.5
Max FPS: 85.2
2360x1440 2xAA fullscreen
Ultra
Disabled Tessellation

Contact EVGA as they'll be the best people to help you. It's possible it's a simple solution or the card could be faulty.

I contacted EVGA and we found out that the cpu is the problem. I tried power settings in windows and in the bios, but it hasnt gotten any better. Does anybody have suggestions?
