Hello! Last week me and my friend built my new gaming PC.

And today, when I for the first time tried a demanding game (Battlefield 4) I got really low FPS, and I have no clue why.

I've tried to re-installed my Windows 8.1.

And I have probably re-installed my Nvidia drivers a total of 10 times with a clean install. Both the new and the older driver.

I've re-installed my motherboard drivers 2 times.


I don't have lag on any other games. But maybe they too run at lower FPS than they should with my setup, idk. (Just ask me if you want me to do some benchmarking)

The FPS in Battlefield 4 is around 40-80 FPS in 1920x1080, with everything maxed out. And 1-5 FPS in 5760x1080 maxed out. And when I turned off MSAA I get around 20 FPS in 5760x1080.


My specs:

GPU 2x MSI GeForce GTX 980 Gaming 4GB PhysX in SLI

CPU i7-5930k with a H100i cooler.

motherboard ASUS X99-A, Socket 2011-3

RAM 16GB of Corsair Vengeance DDR4 2666MHz

And Battlefield 4 is running on a WD Red 1TB NAS Harddrive. (I also have and SSD)


Nothing is overclocked yet. But once I get this problem sorted out I'll overclock the CPU.

And temps are running totally fine on CPU and GPU.

It sounds like you don't have SLI enabled.

What PSU do you have? Can you monitor CPU and GPU usage while in game? I know I had an issue with BF4 at one point where my CPU was only using about 40% of it's capacity and killing my frame rate. After an OS reinstall for an unrelated issue it went away so I am unsure of what caused it to work correctly but it's a good starting point to make sure that your components are not being throttled or holding back for some reason.

Check your CPU and GPU core clock as well while in game. You can use MSI afterburner/rivatuner in conjunction with HWinfo to display these onscreen while you game.

It sounds like your software set up is incorrect

Windows
mb drivers
graphics driver

in that order

burdenbound I download MSI afterburner and found some interesting results. It said my Vram usage reached 4GB on 5760x1080. And it also said both my GPU usage and GPU power reached 100%, on both ones.

My GPUs are running at 1190 clock speed, with a top at 1342. And the CPU runs at 3600 MHz

And how on earth can BF 4 use 4GB+ of Vram? With antialiasing turned OFF. And 2900 MB on 1920x1080?!

That does seem like excessive RAM usage...I don't have an answer off the top of my head but at least we have a clue as to what is going on. I would start to play around with individual settings in game to see if you can bring it down, try playing with shadows and all the other fancy sounding settings which might cause your VRAM usage to increase.
