Low framerate in quick race

    Nope, with a bottlenecked system of any sort you should not be able to run 60 fps with 1hz picture chopping! No way...
     
  2. You can throw all the GPU horsepower you want at it, if you are CPU bound (which is the case if 5 ai perform correctly but 20 is unplayable) you will still be SOL.

    Here in a month or so I will be upgrading my 2500k to an i3 8350k; very curious to see how my 1060 will perform after this upgrade.

    Why an i3? Get an i5 minimum for gaming...

    Just few days ago changed my CPU from i5 3570k (which isn't much better than your current one) to i5 8600k and I have GTX 1060 6GB like you do. Other than simracing games FPS gain was nonexistent as I expected. In AC I got few frames more in benchmark test and in ACC, yes I got better frame rates but not that significant.

    There's my AC benchmark results. AC Benchmark.png

    You should buy i5 8400 instead of i3 8350k. You get two more cores with same prize and as far as I know it has better Performance in games.

    AFAIK the benchmark test in AC is not CPU intensive, you should have tried a race with 20+ opponents to see the impact of the CPU upgrade on the performance...

    Looks pretty similar to me, besides I already got a hella deal on the 8350 so it is on the way. Once I have a new mobo and ram if performance is still an issue I will sell it all and slowly build a top of the line i7 system.

    The comparison between the i3-8350K and the i5-8400 is interesting. I would like to know more about how many cores ACC will use. # cores against core speed. The 8350K seems to be the new 2500K monster that gave me soo many years of power.

    Custom PC magazine (Feb 2018) used an i3-8350k in their budget build and overclocked it comfortably to 5GHz. It's a great budget gaming CPU. Also, take a look here if you haven't already: https://www.tomshardware.co.uk/intel-core-i3-8350k-cpu,review-34095.html

    Running ACC with a I7 2700k @4.2 Gtx 980ti most settling on low about 60-70 fps runs smooth no issues so far .

    Problems will come when VR lands, if i can hotlap in VR ill be happy with that while i get my $$$ ready for new PC in time for multiplayer

    is there anybody who can achieve 60fps during race AND replays on high or epic settings?

    With my laptop the Lenovo Legion Y520 with the following specs:

    Intel Core i7 - 7700HQ - Quad core (4) - Kaby Lake - 2800 MHz,Turbo Frequency 3800 MHz - 6Mb Cache
    NVIDIA GeForce GTX 1050 - 4 GB GDDR5 SDRAM
    RAM: 16 GB SO-DIMM DDR4
    512 Gb NVMe PCIe SSD

    I can run AC with medium, high settings smooth when having 24 cars on the grid. For ACC the story is different. Hotlap, Practice are fine but in races (18 cars) the FPS is quite bad. I assume there will take place quite some optimization by Kunos to make the ACC run more smooth.

    I get significant stuttering in the 35 min stint mode too, which starts at sunset and has time acceleration just like the race, so I don't think it's an AI problem as much as maybe something related to the dynamic lighting and/or the time acceleration.

    I have a GTX 1060 3GB, i5 4570, 16 GB RAM.

    Will just ask here:,does anyone know how memory is used in acc? I noticed its hardly using any memory,on top windows using 1.9gb,runing acc gets me to only 4gb of usage (2.1gb for acc in this case). Im talking about system memory not vram.

    Edit: scenario is 20 Ai cars.

    Same issue, very similar hardware spec. I believe it may be due to texture loading for sunset and night scenarios. Defintely not an AI issue as if I run same number of AI on a fixed time there is no issues. RivaTunner stats shows all 3GB Video Ram being used. Also, my current GPU runs in PCIe 2.0 which may be a reason of stuttering related to texturel oading.

    I’m not, and I have a decent PC, playing at the settings in my sig. Runs at 60 some of the time but drops into the 40’s a lot during the replays, especially race replays.

    Hi everyone,

    Does anybody knows whether the update 2 of ACC brings any improvement in CPU occupancy by AI? Or does it still require a $$$ CPU to run correctly?

    I'm still waiting for such an optimization before buying the game again...
