fps drops gtx 970

[dsx1]

Hi

I was playing Ethan Carter and Witcher 2 recently and I have noticed that fps drops from stable 60 to 10-20 fps with no reason.

I have checked a lot of different forums and so far I have done:

- checked my temps. CPU stays always below 50 C and GPU goes max to 74 C.
- disabled AMD cool and quiet
- disable AMD turbo boost
- disabled firewall, antivirus, internet connection
- defragmented both disks
- install game on different disks
- re-installed both win 8.1 and win 7
- scanned system with malware-bytes and windows malicious removal tool
- re installed nvidia drivers in safe mode
- unpark cores
- tweaked nvidia control panel

Nothing works so far and I am start to think that my cpu bottlenecks video card. I have checked resource monitor and most of the time cpu usage is on 40%..

My rig:
FX 8120 OC 4,1 GHz - Zalman CNPS 10X Cooler
Palit Jetstream GTX 970
24 GB Ram: 16 GB Corsair Vengance + 8 GB Samsung both 1666 Mhz
PSU Xfx 550 W
Toshiba 1TB and WD 500GB both 7200 rpm

Many thanks

Try turning your fan up, my Palit GTX 970 throttled at 63c for some reason, around 70 it'd drop quite a bit more.

Done that, no improvement.
I have noticed however power/core/mem drops at the same time fps goes down.

Do you have another PSU to try? Maybe it's struggling with the load.
