Hello, guys, I came here after googling nonstop, pulling my hair out for the past 3 days.

I had a pc with a 4790k, 980ti, 32 GB DDR3.. a 950W Corsair Modular Power Supply.
Was working great, except the temps, they were rising high on the sky at 80 degrees celsius with a h100i GTX cooler.

The computer is running Windows 8.1.

So I am a game developer, and I wanted to get a 6700k to do some performance tests.

So i got myself a 6700k, with a asus z170 Deluxe and some corsair 2x16GB Ram Sticks.
I replaced those parts, and booted, windows automatically adapted to the new mobo and cpu and ram, so i didnt have to reinstall anything. I updated the BIOS to the latest on the asus page, then installed all drivers, restarted many times, even removed overclock just to be sure.

For example, in the test map of our game (very small, very little objects) i used to have around 450-700 fps when uncapped, now laying down in 180-220.
Also played a league of legends game, when i noticed my previous 350-500 fps be all the way down to 60-200 fps. Very unstable too.


What steps could i take to find/narrow down the problem?

Thanks.

Here's your situation ... You boot your computer and it goes ....

a) Hey, I am loading drivers fro hardware I can't find ... what the hell ?
b) I see hardware that I have no hardware drivers for .. what the hell ?

You can attempt to uninstall all those old drivers and you can then reboot and install the correct drivers (not from Windows Update mind you, that would be a very bad thing) ... tho this will leave a ton of crap behind and introduce issues that no developer should want on a PC used for testing.

I would recommend:

1. Back up what you need
2. Wipe the drive and install the OS fresh
3. Install the component drivers / utilities from the media that came in the boxes
4. Turn off Hardware driver installation in Windows
5. Run Windows Update ... like 17 times ... until it says 'no more stuff"
6. Go to each component manufacturer's web site and d/l and install latest current drivers, utilities, BIOS, firmware.

While useful for you intended purpose (testing) you will not see any significant performance increase over the old CPU
