Huge fps drop on games after upgrading to Windows 10.

I recently upgraded to Windows 10 because there are a handful of upcoming games that I am interested in that are only available from the Windows store (Gears of War, Killer Instinct, and Quantum Break), and I also want to take advantage of dx12 when games start to utilize it. I've read that some people have noticed a minor dip in fps after upgrading, but my experience was so bad I had no choice but to revert back to Windows 7 Ultimate.

Examples:

Rise of Tomb Raider- Windows 7-max fps-62, min fps-43. Windows 10-max fps-44, min fps-31

Just Cause 3 Windows 7-max fps-54, min fps-30. Windows 10-a consistent 30 fps.

Project Cars Windows 7-max fps-118, min fps-88. Windows 10- max fps 88, min fps-73.

Mad Max Windows 7-max fps-111, min fps-88. Windows 10- a consistent 60 fps.

These represent more than just a "slight drop" in framerate which I was willing to accept. Is anyone else having similiar issues with their gaming rig?

Delete previous versions of Windows. Makes more space and PC will run smoother.

On a SSD, but the OP didn't said he got a SSD, and by delete the previous version of windows, the OP can't go back to windows 7.

Did you check the temps on the GPU and CPU? drivers up to date, include motherboard

I should mention that I'm gaming on a 4k monitor, and I do have an SSD drive.
