GTX 760 60% usage in BF3, whats the bottleneck?

I bought a new GTX 760 recently and whilst playing BF3 realised that it is only being used at 50 - 60%. After a bit of research I found that this GPU should be at 100% in BF3, so (I think) its being bottlenecked by something.

Specs:

Mobo: Intel Extreme Series DP55KG
CPU: Intel i5 661 @ 3.6GHZ (stock)
RAM: 4gb DDR3 1600mhz (but I haven't enabled the XMP profile so its running at 1333mhz)
GPU: MSI OC GTX 760
PSU: Corsair TX 850w

I'm assuming it's the RAM that is bottlenecking, what do you guys think?

Thanks in advance,

  1. what is your framerate anyway?
    Cpu should not be a problem. And I do not think ram is doing any bottleneck.

    32 players I get 45 - 60 fps and it is constantly changing.
  3. This card with no bottlenecks should give around 80 fps with ultra settings and 1080p resolution.
    Try to update drivers and check temps of cpu and gpu.
    Also check other settings (lower) within game and the single player mode to see if you have the same fps.

    I'm running setting lower than the recommended ones but ill try getting a new driver, one came out today.
  5. that's weird...I would reinstall everything

    btw why dont you think its the ram?
  7. just updated drivers, usage is now around 48% in game, but 70 - 80% in menus?!?!?!

    Eh, I think the CPU and RAM do have a factor here. While the 760 is capable of playing BF3 on high settings, your CPU isn't. The i5-661 is Intel's 1st Gen i5. The performance of that i5 generation are equal to the Core2Quad series. I had a Q9550 @3.4 Ghz and it was pegged playing BF3. I had a 460 GTX paired with the Q9550. I know that my Q9550 wouldn't be able to fully support a 760 GTX let alone the 480 GTX of the same generation. (The 760 is more powerful than a 480). That i5 is also a dual core with Hyperthreading. BF3 doesn't use hyperthreading which means it's simply running on 2 cores. BF3 loves quad cores. It's optimized for it.

    Furthermore, it is possible to play BF3 with 4 GB of RAM. However, I found (as well as others), BF3 ran smoother with 8GB of RAM. Less shutter.

    Thanks, I'm not planning to upgrade my system (mobo + CPU) for a good while, so which small upgrade do you think would make the most noticeable difference? Would it be the RAM? would an ssd make any difference (just for curiosity's sake).

    RAM is probably the cheapest upgrade that will render a performance change. A SSD will only help with load times. That's it. Once the map has loaded, the SSD is done. It then all falls back to CPU, RAM and GPU. One think you want to be careful of is buying RAM in pairs. You only have 4 GB. I suggest you scrap that and buy a pair of 4GB modules. It is possible to mix modules but it's not recommended because stability issues can arise. Pairs of sticks (or tripple/quad sticks) are rated/tested to work together so there won't be any stability issues.

    My personal favorite is the G Skill Sniper, but there are other good ones like the RipJaws, Corsair Vengence, Patriot Viper and Kingston HyperX.
