Full Release Preformance Issues

I have not been able to keep a stable 60 or even 30 fps not even on the lowest setting.
Specs:
GTX 1060
Intel i7 7700HQ 2.80 GHz
16 GB DDR4 RAM
Windows 10

I sometimes get 60 frames and then as soon as I try to move or do any thing it will dive down to 1-15 frames and then go back to 30-35 and then to 60 and finally drop back to 1-15 repetedly and often. It mostly happens when doing actions too fast such as sprinting or turning the camera too fast. This is extremely frustrating and game breaking.

I would really like this to get fixed. If anyone could suggest anything that would be great.

Thanks

do you have anything open while playing the game, it could slow the game just a tab if you do or maybe update your driver if the game has an update please update, your system could be lacking in hardware: Windows
OS: OS 64-bit Windows 7 or 64-bit Windows 8 (8.1)
Processor: Intel CPU Core i5-2500K 3.3GHz, AMD CPU Phenom II X4 940

Graphics: Nvidia GPU GeForce GTX 660, AMD GPU Radeon HD 7870

Additional Notes: These are preliminary system specs and can change!
must have or higher to play the game.

if everything i have said did not work please tell me.

I have the exact same problem, see my thread here:

The same as OP. The goes down from 50 to 15 very often, and then back up, repeating every half a minute or so.

I have the latest driver (Geforce 1080) and have not run any other program.
