Will there be at least some increase in FPS if I change the PCI Express slots?

Question

ASUS

Good day. I really need advice from people in the know. Has Asus H97-PLUS motherboard (www.asus.com/en/Motherboards/H97PLUS) and ROG STRIX-RX460-O4G-GAMING graphics card (www.asus.com/en/Graphics-Cards/ROG-STRIX-RX460-O4G -GAMING). The motherboard has two PCI Express slots for video cards. Gray and black. The gray one is 1 x PCIe 3.0 / 2.0 x16 (x16 mode), and the black one is some kind of stripped down one (1 x PCIe 2.0 x16 (max at x4 mode) and even with a note that it is somewhere in the BIOS. The video card is plugged into the black connector I play GTA Online, I get a stable 58-60 FPS in 1080p on high settings. Sometimes, of course, it freezes when you drive into the grass, but very rarely. But just today I was thinking, maybe rearrange the card in a gray slot? It seems to be better according to the characteristics? Or with this card I will not get any increase? The card seems to support PCI Express 3.0.
Help me understand these x16, x4, x8 and so on.
I am attaching a screenshot of GPU-Z with a black slot.

Thanks everyone!

Answer 1

Most likely there won't be a difference. Two or four frames, and then hypothetically, but what the hell is not joking?
Here is the situation. You have a mat. The board has two PCI-Express x16 slots and two PCI-Express x1 slots. The first, closer to the processor, PCI-Express x16 slot always works in 3.0 or 2.0 x16 mode. The second PCI-Express x16 slot actually works in 2.0 x4 mode, i.e. 4 lanes per slot, but it shares those 4 lanes with two PCI-Express x1 slots, plus a network card and an M.2 slot. If the second x16 slot in the BIOS is configured in x4 mode, then the PCI-Express x1 and M.2 slots will not work for you. Otherwise, it is configured according to the "x2 + x1 + x1" scheme, that is, then two PCI-Express x1 and M.2 slots work.

See the FPS test of a video card on different PCI-e versions here:
