Re: BF2042 CPU Running At 100% Constantly For No Reason

@necropxhyte well it seems you didn't read the ned of my last message: there is a lot of kernel time on the cpu, so yes the game may use 8 or more cores but most of the times they wait each others, thus implying the 100% cpu and bottleneck , and yes as the thread wait for others the renderer thread is in the same state.
anyway poorly optimised code for sure. (it reminds me the mouse feerates dependant to the framerate when dishonored 2 was out until the patch.. i know the dev who did that had a bad time because of that)

    @psychotik2k3yes, my reply was to this comment: https://answers.ea.com/t5/Technical-Issues/BF2042-CPU-Running-At-100-Constantly-For-No-Reason/m-p/11054168#M14270
    (low gpu usage > low gpu wattage because the gpu waits for the cpu, not because the game doesnt use it; and low fps are due to the cpu bottleneck, not due to the low gpu usage)

    looking at the new bf2042 rush mode (as well as other portal modes), it is just even more obvious, performance is generally less bad, but there are still cpu frametime spikes to 3-digit-ms, hence huge fps drops, and avg cpu-rendered fps is still below the server tick, all this without any cpu clock throttling or utilization drop, while the gpu renders 70-120+fps flawlessly, and this on a mix of a few low, mostly medium-high settings. hence, comparing apples-to-apples: bfv (64 players) runs far better (and looks far better, and has destruction, which in bf2042 is laughable) than bf2042 with 64 players on basically the same engine > obvious lack of bf2042 optimization, which fits to the overall state of the game

  • yeah i think we misunderstood each other.

    and yeah saddly the game optimisation is far from correct when you see that even some I9-11XXX got the problem while they do have lot of physical cores.

    But i noticed that it's mostly INTEL cpu , on AMD side it either 1 or second gen ryzen, but no 3000 or 5000 series.
    I will try on my living room computer which holds a ryzen 5 3600, the gpu is only an rtx2080 but it will be enough to see if i do replicate this behaviour or not.

  • strange what ryzen 5000 do you have ?

    i have a ryzen 3600 with rtx2080 and tested this lunch time: cpu at 50-60% maximum and so thanks to that this rig is faster than the one ith the rtx3080 😕ob

    and freidns who got ryzen 5 5600x got no problem at all too.

  • Do you have smt or is it disabled?

    Because when I tested on my r5-3600 rtx2080 rig this is the CPU usage and we clearly see it needs at least 7 or 8 virtual cores

    Disabled or enabled the same perfomance, maybe 10fps on off.

    This is what it looked like in a rush round - fps is in the 80s, Higher than AOW modes.
