    Hi,

    I got the following setup:

    Motherboard: asus p6t deluxe v2
    Cpu: i7920 D0 @ 4.2ghz
    Gpu: msi gaming x 1070
    Ram: 16 gb
    Ssd: samsung evo

    I play games at 1440p, I was playing battlefield 1 on ultra but in some maps the fps drops below 60 even pn low sertings. I thought it was my ram coz i had 6gb but i updated it and its still the same. I noticed my cpu is at 100% playing bf1 but i thought its just a normal thing.

    Do you think is my cpu bottlenecking my game experience?

    BF1 CPU requirement is atleast i5 6600k. Skylake CPU's have miles faster IPC than very old Bloomfield.

    So yes, your CPU is limiting the performance of 1070. I would recommend you wait for AMD Zen (very close) and Intel Kaby Lake then decide and upgrade.

    Yes.

    I saw the same thing with my old q9450 in bf3 back to krakat? Dlc.

    I guessed it, thanks guys, I'll wait for Zen to arrive, Kaby doesn't seem to improve a lot from Skylake processor, or at very least Skylake will drop their prices down, tho it's afforable the 6700k price right now.

    OP, 100% CPU usage while playing BF1 @ i7-920 D0 4.2GHz happens both with HT ON and OFF?

    I dont think it makes any difference. BF1 needs strong per-core performance.

    HT ON should make a difference in BF1, at least a bit.

    I agree that BF1 would benefit from faster per-core performance CPU and i7-920 @4.2GHz is a bottleneck for GTX 1070. As others have already suggested waiting for Zen would be a good idea.

    Hi there

    I would personally upgrade CPU to X5670 or X5675, those chips are great,will run less vCore and run lot cooler than i7 chips plus have run X5670 with Titan X and no bottleneck issues

    Hope this helps

    Thanks, Jura

    I know that an i7 920 isn't going to give you the performance of newer cpu's, but I have had cause the last week to stick my GTX 980ti Matrix into my old I7 920 @4Ghz .. I've played all my games from WOT to Battlefield 1 at 2560x1440x165hz and I can play them without an issue and certainly at frame rates that didn't come close to being annoying .. I've usually got a GTX 970 G1 in it but I did see a good deal of an increase in performance with the 980 ..

    There is a difference actually. I was just running BF1 on an i7 950 @ 4.1ghz on a friends PC.

    It not smooth with HT off, but with it on, it was super smooth. It didnt really affect the framerate but made the game run alot better.


    Its the same way with my 3930k. BF1 feels alot smoother with HT on and cpu usauge is alot lower with it on.

    For the most part, the 920 @ 4.0+ can keep up enough with a 1070 @ 1440p. At 1080 it would be more of a bottleneck.
    If anything get a $99 X5650/70 6 core Xeon and overclock it. Ive had 2 and they do fantastic when @ 4.2ghz+. Even my x5670 stock @ 3ghz boost plays BF1 just fine with a 290x when testing.

    oh there is a difference I agree, but not what I thought there might be. The game was certainly playable. No not creamy smooth but not annoying.

    Like others have said, just get a Xeon 5650 or 5670 second hand for ~$80+( depending on which cpu you go for ) and overclock it to 4.2Ghz or 4.4Ghz ). Its cheap, runs cooler than the old 920, overclocks higher and obviously has 6 cores. The frostbite engine scales brilliantly with 6 cores.
