Q:
Low Framerate in game
A:
Well that settles it, your video card is not behaving correctly (assuming that screenshot was taken while you were playing). Like it was suggested, make sure your video card is in the slot closest to the CPU. even if it is take it out, take the power cord out and put it back together. If no help, reinstall the latest drivers.
12 max where? All time max anywhere you’ve been? If it’s WvW zerg or other situation that involves tons of other players I’d say that’s about what you could expect.
If it’s everywhere, download a program called GPU-Z. Check your Bus Interface, Core Clock, Temperature and GPU Load. Give us the numbers you see in those.
Did you plug your video card into the correct PCIe slot? Only one is actually x16, the other two are actually x1 and x4.
The slot closest to the CPU socket is the true x16 slot.
If the video card is already in the correct slot, you can use GPU-Z to double check that the video card is talking to the motherboard over an x16 width bus or not. The “Bus Interface” info is about halfway down on the right column of GPU-Z. It’ll tell you what the video card can do and what the current connection is.

Core Clock: Average 799MHz
Temperature: Average 33.2°C
GPU Load: Average 40%
Bus Interface: PCI-E 3.0×16@11.1
Low framerate everywhere
Please put up a screen shot of GPU-Z, the Bus Interface data doesn’t look right.

Yeah. Thats a x1 wide link at PCIe V 1.1. That’s 250MB/s instead of the 15760MB/s.
The card is in the slot closest to the CPU right?

I moved it to the slot nearest to the cpu now im getting 60 fps . Thanks for the help.
Why does moving it to the other slot make such a difference?

The closest slot to the CPU is the most populated slot when it comes to PCI Express lanes. The more lanes, the more bandwidth can be sent through it. The highest lane count is X16 and after that it goes x8, x4, sometimes X2 and then lastly, X1. The lower the lane count, the lower the GPU performance. Every PCI Express slot below the one nearest the CPU is a secondary one but on any mainboard with more than one PCI Express slot, typically there is always at least one slot that has a full x16 lane connection. Some very high end motherboards could be designed otherwise to have multiple X16 lanes PCI Express slots even if the processor doesn’t support having more than 16 lanes (such as my own) and you could potentially look at it as alternative locations for a GPU.
The game can still play fine on an X8 lane slot, which for people using two graphics cards on a regular CPU (like me, 7970 Crossfire and i7 4770K,) each GPU splits one X16 lane that the CPU can handle, (i7 4770K has 16 lanes for graphics) and they both run at X8. No single GPU will always fully utilize 16 lane all the time. Maybe a dual chip card (7990, GTX 690, GTX 590, so on)
However, extreme edition intel i7, (3960X, 3930K, 4960X so on and other six core processors) are fully equipped with 32 lanes so you can have up to four graphics cards running at X8. It’s a tonne of power.
But yeah essentially, more lanes in use on a PCI Express slot, the better the GPU performance and the faster that it’s being fed to the GPU and thus being sent to the monitor for you to enjoy your digital experience.

Why does moving it to the other slot make such a difference?
Because even though three slots look the same, only the one closest has all 16 PCIe lanes from the CPU wired to it. The other two slots are pulling their PCIe lanes from the H77 motherboard chip.

I actually didn’t know that the additional lanes came off the chip. So I guess I have an additional x8 and x4 coming from my Z87. (Asus ROG Maximus 6 Formula)
No. The Z87 allows the x16 from the CPU to be split into x8/x8. The x8/x4/x4 configuration is likely using a PCIe splitter of the x8 into two x4s.
If it’s only V2.0 lanes, those are from the motherboard chip. The Z87 has a total of 8 V2.0 lanes.

Z87 Motherboards have a User accessible 16x v3.0 Lanes from the CPU. The 8x v2.0 Lanes are for the onboard devices and are not split off to any of the PCI-E Slots, those are tied into the Z87 Chipset for your LAN, Audio, USB3.0 Headers…ect.
All Z87 Systems are 16x, 0x, 0x, ; 8x,8x,0x ; 8x,4x,4x; for their addon card support. And while 8x v3 is as fast as 16x v2, I still get better Low end FPS by keeping my card at 16x v3! So I do not use my other PCI-E slots at all. Even my 4 1x slots take away from the 16x Lanes from the CPU (it will actually knock my GPU down to 15x if I put in a PCI-E 1x NIC).
If only the Onboard 8x lanes were user addressable!
