The Decklink Duo 2 only requires a 4x PCIe-lane, and although the slot may be physically 16x, the motherboard may have routed some of those lanes to other things.
Worth a check to verify this setting in the BIOS / UEFI or the manual. Consumer motherboards especially have this annoying design where the slot may be 16x, but you can never get full speed on the link.
