Low CPU usage BF2042

I am new to BF2042 and have noticed that my CPU usage never exceeds 40%. I have a RTX 3080 that runs at about 95%. my CPU is an i7 12700k. I have noticed that only about half of the cores are being utilised. I would have thought that a game like battlefield would use more CPU. I have tried creating the user.cfg file to enable more cores, however I didn’t notice any difference to the CPU usage, but I can see that almost all the cores are now being utilsed. so is 40% CPU usage normal for my setup?

  • That was indeed the case for a workaround with previous patches.

    Also think even though your Alder Lake CPU is listed as a 12 core... it has 8 performance cores with HyperThreading and 4 Efficient cores, so if you modd the cfg, I would only pick 6-7 cores maximum.

    Why not up to Medium detail level ? The performance impact should be minimal on your setup.

  • 40% CPU usage sounds about right. 12 cores is quite a lot for 2042. 2042 likes the main cores being REALLY REALLY fast, so not utilizing all your cores hopefully boosts the main performance cores really high so you get a good performance.

  • Thanks Carbonic. So I probably don’t need to run the User.cfg file to unlock all cores?

    the internet seems to think this is the holy grail of increasing performance. I didn’t really notice any difference when applying this optimisation. I seem to get a smooth gameplay experience and average around 150 FPS on low settings.

    @Adamtronik Do you have slight micro stutter when running sometimes also at feels a bit like lag. Only asking because you have the exact same setup as me… cheers

    Hi Liddle, I get no stuttering at all, it’s actually really smooth. I run Windows 11 and have DDR4 64gb ram. On my older PC’s I would get bad stuttering on battlefield games, so I would have to cap the frame rate so the GPU would only work at about 70%, this removed all stuttering. On my new PC I dont have to cap because it’s really smooth and the GPU runs at about 95%. I also did some testing with direct 11/12 and found no difference with either, but I did find if I enable direct x 12 but disable future frame rendering in the in-game settings I got a lot better 0.1% fps lows, but the average fps was the same. So maybe do your own testing with different combinations of direct x 11/12 and future frame rendering.

    @Adamtronik @My GPU runs about the same as it’s exact same system but I use DDR5 ram 32GB. The stutter is like almost one frame backward when running but it is high fps so it can’t be performance related

    cheers

    Have you had a look at the troubleshooting guides on here?

    have you the latest bios and chipset updates?

    Are you using a ssd drive and do they have an updated driver (windows wont install automatically). 

    Also, have you done any testing with bios settings? things like resize bar, ram remap etc? I got a lot better 1% low fps results by enabled ram remap. check out Fr33thy youtube videos for windows and bios optimisation guides.

    also, not sure about your drive setup, but I have all games installed on a second ssd drive (samsung evo pro 970). is your hardrive almost full? this can degrade performance too.

    Mate this game doesn't work with DX11. It's all placeboo. You can't run this game in DX11 its a DX12-only game.
