Optimisation for less CPU usage!

Discussion in 'ACC General Discussions' started by Stian Verherstraeten, Jun 4, 2019.

  1. I have an intel i5-7300hq processor with a Nvidia GeForce GTX 1060 6gb. Normally the game should run quite well on the graphics card, but the problem is that it wants to use my CPU more than the GPU... Is there any fix to make the game run smoother? (I turned down all the settings to minimum and still only get about 35FPS and about 15 when I play with a full grid...)

    Laptop, yeah? Have you checked for thermal throttling?

    No I haven't What exactly does it do?
    I'm on laptop indeed
  5. Where do I find the crash log files please

    The main settings that are affected by CPU performance are the number of opponents and to a lesser extent visible opponents. So you can run higher graphics settings if you want, but you probably can't play with a full grid if you want it to run smooth.

    I run 13-16 opponents depending on track with an i7-4790k, for reference.

    Plenty of laptops can't sustain full clock speed on their CPUs - they simply don't have the cooling capacity. So when the temperatures get to a certain point, the clock speeds drop to prevent the CPU (or indeed GPU) getting cooked and killed.
    Easiest way to tell, with stock Windows 10: run Resource Monitor and get yourself on the CPU tab. Then run the game and after a minute or two, alt-tab back to Resource Monitor. The top right panel will have a green line for CPU loading and a blue line for CPU clock speed. If the blue line is pegged to the top of the chart, all is well. If it's dropping away, you're probably throttling (or the CPU demand is low enough that it's just slowing the CPU cos it has nothing to do).

    Did you post in the wrong thread by accident Jim? ;)

    In any case, try looking in
  9. I'll check that! Thanks :)
    Oh and if I'm indeed thermal throttling, is there anything I could do 'against' it?

    My cpu was bottlenecking my GPU, i turned the mirrors off and now gpu is almost 100%, try turn them off too.
  11. Probably but I've never known where to find these crash logs but thanks for the info.

    Yeah, thanks. I tend to forget that I have Explorer set to show hidden stuff...
    Well, if your laptop is brand spanking new, probably not, cos it'll be running with the cooling as good as it gets**. But if it's not totally new, I'd consider blowing the dust out of it. I tend to do this by literally blowing really hard into the cooling intake (often underneath) and closing my eyes because there will probably be a huge cloud of dust. On several laptops I've "cleaned" this has made a big difference to the throttling. Do try not to spit into your laptop though ;) :D

    ** You can buy special laptop cooling bases with fans on them. Dunno if they help though.

    Edit: if you are confident about taking your laptop apart, you can get it cleaner that way, but it's a lot more work...
  15. I found it thanks.

    They do! I had one with 2 fans which you could replace anywhere underneath the notebook to match the positions of CPU/GPU. The difference was ~10 degrees for both GPU and CPU. Since notebook GPUs/CPUs run up to 85/90 degrees, that actually helped quite a bit.

    But before buying new stuff or taking the notebook apart for cleaning, I'd just try ACC after a cold start and jump into a session, immediately. Your GPU and CPU will then be "cold" and you can compare FPS - if they're also low, then thermal throttling isn't your problem. Makes sense, no?

    Edit: something else: some performance notebooks (like mine) rely on using both the battery and the AC to provide enough power to GPU and CPU. When I play with my notebook on a weak battery (while plugged-in), the FPS go down, a lot!

    Yes you can .

    for GPU temps
    you can go download
    Msi After burner frorm here:


    and set a very aggressive fan speed curve , if it doesnt work u need also need to change the thermal paste here too,unless is a laptopthen i would not even reccomend any of this .

    for CPU
    you may need to ask ur self when u changed the thermnal paste of ur cpu last time .
    After u done it. check if the system is stable
    to do it
    Download AIDa 64

    the start a stress test for 10-15minutes

    if you system lock up during the stress test , restart ur pc ,enter the bios and used default configuration for ur system .( no overclocking stuff )as it was when u bought it.

    sometimes is just thermal paste getting solid

    Those numbers are far from normal. I got quite same specs on my pc but with the red team (Ryzen 5 1600 and Radeon RX580 8gb). I drive at 1440P, medium settings and few items at high and I get no less than 60 FPS both online anf offline with full grid. In my case my bottleneck is caused by GPU. Remember to set virtual mirror to low or medium it causes a great frop of FPS.
