RX470 way underperfoming

[Pizzapaz001]

As of late my fps has dropped compared to what it used to be before. I used to have fps very similar to this video: 

But recently with the same settings used in this video  (which are the same settings I used when I still got high fps) I don't even get a stable 30 fps. Using msi afterburner I saw that the GPU is at 100% at all times during gaming while the processor doesn't go much higher than 45%. I have not overclocked this graphics card.

 

 These are the parts I got:

Motherboard: Asus P8Z77-V with bios version 2104 

CPU: Intel Core i7-3770k OC at 4,5GHz

Ram: 2 sticks of 4GB ddr3 Kingston hyperX genesis gray series 1866mhz

Graphics card: xfx Rx 470 black edition 4gb

Monitor: LG 29UM68-P 2560x1080

 

Thanks for any help in advance!

First of all I want to say that I do not have any experience and I'm just searching on other topics to look for solutions.

 

- In this same Topic it was fixed by reinstalling windows but that I would look to some other options first because a full reinstall is the worst thing to do

 

- Another fix that helped someone with a rx 480 (only use if u had an old nvidia GPU):

Remover all your drivers (Nvidia from the old GPU and AMD from the new one) with DDU:

install AMD Drivers only.
