1. Do you need support for Assetto Corsa Competizione? Please use the proper forum below and ALWAYS zip and attach the WHOLE "Logs" folder in your c:\users\*youruser*\AppData\Local\AC2\Saved. The "AppData" folder is hidden by default, check "Hidden items" in your Windows view properties. If you report a crash, ALWAYS zip and attach the WHOLE "Crashes" folder in the same directory. Do not post "I have the same issue" in an existing thread with a game crash, always open your own thread. Do not PM developers and staff members for personal troubleshooting and support.
  2. As part of our continuous maintenance and improvements to Assetto Corsa Competizione we will be releasing small updates on a regular basis during the esports season which might not go through the usual announcement process detailing the changes until a later version update where these changes will be listed retrospectively.
  3. If ACC doesn't start with an error or the executable is missing, please add your entire Steam directory to the exceptions in your antivirus software, run a Steam integrity check or reinstall the game altogether. Make sure you add the User/Documents/Assetto Corsa Competizione folder to your antivirus/Defender exceptions and exclude it from any file sharing app (GDrive, OneDrive or Dropbox)! The Corsair iCue software is also known to conflict with Input Device initialization, if the game does not start up and you have such devices, please try disabling the iCue software and try again. [file:unknown] [line: 95] secure crt: invalid error is a sign of antivirus interference, while [Pak chunk signing mismatch on chunk] indicates a corrupted installation that requires game file verification.
  4. When reporting an issue with saved games, please always zip and attach your entire User/Documents/Assetto Corsa Competizione/Savegame folder, along with the logs and the crash folder (when reporting related to a crash).

    Grab the 7700k mate if you have a Z270 board. If your board is a non Z then a 7700 will do and may cost less. Either will be more than enough for 100+ fps at little over 50% load. If at 1080p on the ti, you'll achieve 150+ frames with reasonable settings. Full grid A.I. no worries either.

    Thanks for your reply.

    I'm definitely considering it.

    I don't have a overclocking motherboard on the simulator but the 7700k is clicked higher than the 7700 so would still go with it if I did choose the upgrade cpu.

    It can't be any worse than my old i5-7600K (4c/4t), but you really should invest in a six-core CPU and an 8600K or 2600X with multithreading should do the trick, if you're planing to use if for a few years.

    My i5 4590 can't handle ACC, I get constant stutters both lapping by myself or racing with other cars on track. Tried lowering both resolution and graphics but nothing helps. I'm normally able to play newer games at 2560/1440 on my 1060 gpu when I turn down the graphics a notch and keep a stable 60fps, but even playing at 1080p with mid to low graphics my PC struggles to give me smooth gameplay in ACC.

    Not sure what to do now apart from upgrading my CPU, but seeing I don't have this issue with other games I might not spend that dough just yet.

    I assume there must be a setting or two that may help, I need to test what car amount limit I can do on mine. Im okay with 7 others which is fine for a quick race but not exactly simulator

    Reminds me of the old Gran Turismo grids :D
     
  7. I5-4670k@4GHz here and stutters too. Its a lot better with the last version of ACC. But still there and dangerous when it happens while cornering or braking.
    I'll try a I7-4790k@4.4GHz (fastest CPU for my mainboard) this week. Maybe the higher thread count can help a liitle bit.
    I can't afford the whole change MB,RAM and CPU :(

    ^ I was monitoring it and RAM should be ok if you have 16GB, game just seems to be really heavy on the CPU side of things at the moment.

    I had a i5 4690k and had a lot of problems. But I change to i7 4790k and now work perfectly. The CPU keep around 50%

  10. 16GB RAM=checked :)

    ...sounds good :)
     
  11. Now after the CPU change I've to agree to the fullest. The i7 4790k can handle much higher settings without any problems. Also my CPU keep 50%. It's a much more improvement than expected.

    You're right mate, it's a big improvement.

    I wasn't too surprised by the improvement when going from 7600K to 8700. Others had reported that ACC seems to make good use of additional cores/threads.

    7600K was running between 75 and 95 %. Image got a bit unsmooth starting from 85 %.
    Now CPU usage is between 25 and 35 % and i noticed immediately after the swap that the image was smoother.

    I didn't increase GFX settings, though. Which ones could you increase?

    Anyways, I'm glad you could make this upgrade and have a better experience now. I'm very happy, too - the 8700 is a beast.

    ACC really takes a grunty PC.

    I5 9600k here and everything runs smooth
     
  17. Maybe more specific:
    You'll need more than 4Cores/4Threads ;)

    I hope the game can be further optimized though so people with less beefier CPU's can still run it.

    Can they not run at reduced settings?
    The other side of the coin is I hope it takes advantage of all the CPU/GPU power available for added features and effects
    Any game that can be "maxed out" on mid range hardware is wasting potential

    mister dog Alien

    I'm not asking for a maxed out experience on a mid range CPU, as long as it doesn't end up being a stutter fest on low to mid graphical settings that would be good enough for me (and many others that don't have the latest and greatest).
