My GTX 1080 is Underperforming

So I've been having this problem with my Gigabyte GTX1080 Founders Edition.
I've noticed a HUGE underperforming compared to the many benchmarks that were posted online, and I'm not even talking 4k or 1440p, this is 1080p.

For example, in Fallout 4 i see my fps drop as low as 45fps (in 1080p), but I see other benchmarks get like double or even triple the fps.

In the GTA V benchmark test at 1080p and MSAA x2 I also see it varies between 70 to 45 (mostly in the 50s there).

The Witcher 3, 1080p maxed out AA x2 Hairworks ON and Hairworks AA x2 - about 55 to 75 fps.

It really bothers me to see it performs like roughly half of what I see in most benchmarks since the GPU seems to be running fine (Core clock is as it should be, same for memory clock and temps)
I've tried to run DDU and install fresh drivers a few times and it didn't change anything.

I know there's probably a bottleneck in my rig but does it really make underperform by that much?

As for my rig:

GPU: Gigabyte GTX1080 Founders Edition.
CPU: I5-4430.
Mother Board: Gigabyte GA B85M HD3.
RAM: 2x 4GB 1600Mhz DDR3
PSU: Corsair CS650M 650-Watt 80 PLUS Gold.
Case: Corsair Carbide SPEC-03.
OS: Windows 10 64bit.

I'd really appreciate any kind of help

  1. Best answer
    It must be your cpu bottlenecking your gtx 1080. I have a gtx 1070 with an i7 4790, and I get better results than you.
    Try install MSI afterburner to see if the gpu is running at 100%, it might be running at 70% for example, because the i5 4430 is not fast enough to keep up with it.

    It might sound odd, but at 1080p the i5 4430 is more likely to bottleneck the gtx 1080 than at 1440/4k.
  2. Personally, I don't see how his CPU would be bottlenecking him that much...20-30% maybe but not as much as he is reporting.

    An easy test may be to buy a second hand i5K or i7k second hand on ebay, test it in your system after overclocking it and see if that improves.

    You can return a CPU for full refund before 30 days on Ebay usually.

    Will cost you quite a lot of $$ to replace MB and CPU to Skylake atm - as I am sure you are aware.
  3. In most games it wont, but in games like gta 5 that cpu can definetly bottleneck a gtx 1080 in certain areas, and as far as I know Fallout 4 is pretty badly optimized so that also might explain it a bit.

    But he should run MSI afterburner just to see if his gpu hits 100% while gaming, if its not than the cpu must bottleneck it. if his cpu is at 100% while the gtx 1080 is at 70% well then we know.
  4. Okay, so I ran some tests and here are the result:
    - In GTA V's benchmark test (and some city strolling) I've seen that about 35% of the time the CPU was hitting about 90-97% while the GPU (GTX1080) was at about 50-65%, FPS varied at about 51-89fps.
    - In Fallout 4 I tried to walk around in Diamond City (Which is considered quite a demanding spot in Fallout 4), CPU was at about 65-70%, GPU at about 40-45%, FPS varied at about 44-77fps.
    Both these game were running at 1080p at completely max settings.

    Now I have 2 questions:
    1. Is it considered a bottleneck of some sort?
    2. Why Didn't I see the CPU/GPU utilization % go higher even though it wasn't at that high percentage but the performance also weren't?

    like '' GTA V's benchmark test '' look how may are not satisfied with that game and others to start with ??


    then anything can affect performance across any platform or just the old luck of the draw thing ??

    1. 35% of the time 99% cpu usage, what about the other 75% of the time, around 90%? I think you have indeed a cpu bottleneck there.

    2. It might the game not being 100% optimized, therefor you wont see 100% usage.

    Yeah, in GTA V the rest of the time it's about 90% usage, sometimes I see it fall all the way to 75% but it's always much higher than the cpu.
    Also, is there a way to better optimize it? (I'm pretty new to optimization stuff).
