I need some help from people who maybe enountered this problem already.
I did my latest build recently:
It sits in a FormD T1 v2 case with FormD PCI-E 4.0 riser cable. What I noticed that it works perfectly in PCI-E Gen 3 mode, but when I switch to Gen 4 in BIOS, the graphic performance becomes not just worse, but so terrible that it's literally unplayable in most modern games.
Here is what GPU-Z displays for Bus Interface:
Even if I press (?) button and run GPU test, it doesn't switch from 1.1 to anything higher. I updated BIOS firmware on my motherboard to the latest 4602, but it didn't help.
Is FormD PCI-E 4.0 riser cable faulty? Or, what else could be a problem?
