PCI-E stuck in x2 on PRIME Z370-A

Hi,

So I recently ran into serious performance issues with a game (Wreckfest) and I couldn't make out why that game out of all was performing poorly. After about a week of troubleshooting, someone asked med to check my linkspeed. Voilá, for some reason it runs in x2 instead of x16. Flashed my BIOS and tried looking for any options regarding link speed to no avail.

Card is seated in the top slot, which is the suggested one if you're running a single card setup. Really confused why it's set to such a slow speed and why there's no option to change the link speed. The GPU is a GTX 1080Ti. Let me know what else you need in order to help med troubleshoot this issue, thanks!
