Hi,
I bought a gaming laptop a few months ago and it was great, but after replacing the hard drive by a ssd, my games were running like crap. Now I put back the hard drive and M.2 ssd in the same slots as when I got it but still getting the issue.
For example I can't really play ultra on WoW with a i7 4790 and gtx 980m.
Guild wars 2 is unplayable even on lowest settings.

The main reason for this is my GPU getting to 100% load when FPS drops occur.
So I tried to find the problem and I have found that in GPU-Z, my bus Interface is :
PCI-E 3.0 x16 @ x1 1.1
When I start a render test it changed to PCI-E 3.0 x16 @ x1 3.0

For some reason, Heaven Benchmark 4.0 seems to work fine (avg 45fps on extreme). It does not use a lot of bandwidth I guess ?

When searching for help online, most of the answers were to basically remove and put back the GPU but I'm on a laptop...
I tried reinstalling windows and drivers from scratch using GParted but everytime I get the same issue.

If someone has an idea... I'm interested

 
Hi,

Have you tried doing a clean install of the graphics card driver? Please do try these troubleshooting steps that may help.
- First is to open Device Manager and uninstall the graphics card driver.
- Next, go to Programs and Features then uninstall anything related to the graphics card.
- Once done, download and install the latest driver from the manufacturers site.
Nvidia: nvidia.com/Download/index.aspx
AMD: http://support.amd.com/en-us/download
- Reboot your laptop once the latest driver has been installed.
- Do also make sure that the dedicated GPU is set as the default.

Hopefully this will help. :)
