    so yeah, when there is another car my cpu speed is below 1.00ghz thats so depressing laggy gameplay
    my processor is Intel Core i7-4750HQ 2.00GHz
    i know its below minimum but why oh why its always below 1.00ghz if there's another car, no matter its AI or player

    In my experience, if your system is not meeting minimum requirements, items like this wont get answered readily. If you can over clock your CPU, MB and Video, you may want to do that just to try.
    Unload any and all applications running in the back ground or
    Reinstall your operating system to a dual boot mode. Then run ACC in that OS Partition. Simply you PC is not at Minimum spec

    Minimum Requirements

    Minimum Requirements
    OS: Windows Vista SP2 32-bit (with KB971512 platform update)
    Processor: AMD Athlon X2 2.8 GHZ, Intel Core 2 Duo 2.4 GHZ
    Memory: 4GB
    Graphics Card: DirectX 10.1 (e.g. AMD Radeon HD 6450, Nvidia GeForce GTX 460)
    Graphics Memory: 512 MB
    Hard Drive: 15 GB

    Recommended Requirements
    OS: Windows Vista Sp2 - 7 Sp1 - 8 - 8.1 - 10
    Processor: AMD Six-Core CPU, Intel Quad-Core CPU
    Memory: 6 GB
    Graphics Card: DirectX 11 (e.g. AMD Radeon 290x, Nvidia GeForce GTX 970)
    Graphics Memory: 3 GB
    Hard Drive: 20 GB

    Supported game devices

    Your CPU is not below Minimum Requirements, it actually meets Recommended Requirements.

    The 2.4GHz minimum requirement will only apply to Core 2 Duos - We can see this as the AMD dual core requires 2.8GHz, telling us that not all GHz are equal. So what is the equivalent speed of your i7-4750HQ?

    Passmark Single Thread Results:
    i7-4750HQ @2.0GHz = 1737
    E-6600 @2.4GHz = 907

    Yikes, so even with a 400MHz deficit the i7 slaughters the Core2Duo. Looks like you will be good so far. It gets better though! Let's have a look at the Recommended Requirements:
    • Processor: AMD Six-Core CPU, Intel Quad-Core CPU
    Is the i7-4750HQ an Intel quad core CPU? Yes! In fact it goes a little further than even that requirement and gives you 8 threads to play with - However for simplicity of demonstration let's stick to the 4 physical cores.

    Quick Multi Thread Results (based on single core data (quick maths)):
    i7-4750HQ @2.0GHz (4 Cores) = 6948
    E-6600 @2.4GHz (2 Cores) = 1814

    An absolute mauling, with all cores used the i7-4750HQ is in a different league entirely to the minimum required CPU.

    So in conclusion - your CPU is fine, your CPU dropping below 1.0GHz is not fine. That is the source of the issue, not the processor specification. Ignore anyone who says otherwise and treat this as a general laptop issue rather than game specific.

    i mean its only happen on this game, other game runs fine
    and most importanly it only happen when i play with more than 1 car

    Are you actually using ""Intel(R) Iris(TM) Pro Graphics 5200"? because if that is a yes then it could just be that your "GPU" is getting so battered whenever too much is on the screen that your CPU has to wait for it and starts power saving by dropping the frequency.

    That "GPU" is NOT minimum specs.

    Well spotted, the laptop seems to be using the onboard graphics of the CPU to power save instead of using the dedicated GTX 950M.

    @OP, try these steps to make ACC run with the correct GPU:

    ive done that in a long long time ago but now im modified one of the list above it like : OpenGL Rendering GPU i set it to GEFORCE GTX950M

    i also install ROG Game First III, and everytime i play ACC i set ACC to highest

    i can say ROG Game First III is doing great job its fixing shuttering and lag (but sometimes the shutter still happen)
    and im always play only with 4 AI, no more than that because if i play with 5 AI or more, the performance is just like the old performance before i use ROG Game First III

    thank you for all you guys that supporting me and sorry for my bad english
