  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)!

Massive FPS loss after new update on a 10700k/3090

    I just downloaded the DLSS update today. All of a sudden I have about 30FPS Avg loss. Prior to the update with testing/logging FPS. I would get a low of 100fps, high of 144fps(capped) and an avg of 122fps on a daytime 20 AI race. This is on Triple 1440p monitors with a mix or high/epic and 100% resolution scale on a 10700k@5.1/3090/32gb ram.

    Now after the update I am getting a low of 60 FPS, avg of 85 FPS and a high of 110fps with the same exact settings.

    I deleted all custom files and engine.ini file and started from scratch. This is with DLSS and FSR off. I am running the new Nvidia Driver for DLSS 496.76. All other games are performing as they always have.

    I have yet to try VR which I had dialed in perfectly on my G2 but wondering if anyone else has experienced this after the update. DLSS and FSR do not help get me back to where I was either.

    My apologies, here is the full zip of logs from today. Also, I just uninstalled and reinstalled the game with Steam with the same result. Also FSR even on performance mode only adds about 8FPS.

  5. Hi! Same problem here. I have a Ryzen 5900x, rtx3080ti and 32G of ram 3600mhz! I think is not a hardware problem and don't have this issue in any other game. Another thing i noticed, is i have no difference in fps between high or epic graphics settings.

    I suspect a GPU driver setting, maybe even a windows related setting (Game Mode, or something like that).

    With Game mode off or on it does the same thing. GPU driver was a clean install with DDU. All NVCP settings are identical to previous settings before the update where my performance was fine. Hardware accelerated GPU on/off doesnt change anything. I have no idea what is happening but its extremely frustrating.

    My case is still more serious after updating to version 1.8 I do not have more than 15 fps in training mode and it warns me of cpu usage 99%, in all the games that I have everything works wonderfully with the latest drivers, I have an i7 8700k 5ghz RTX 3060 you, please if someone can help me I would really appreciate it, I have reinstalled drivers with DUU, installed game from the beginning and I have no solution.
    Before the update with high and ultra graphics it was around 115fps at 3440

    Try disconnecting all controller devices and try with just keyboard and mouse. The CPU warning and loss of performance might result from the need to update or reinstall wheel firmware and drivers or set up your controllers anew.

    I will do that. I do have an xbox controller plugged in for other titles and a custom Steam mapping for it

    [QUOTE = "pankykapus, post: 1204457, member: 5570"] Intente desconectar todos los dispositivos controladores e intente solo con el teclado y el mouse. La advertencia de la CPU y la pérdida de rendimiento pueden deberse a la necesidad de actualizar o reinstalar el firmware y los controladores de la rueda o configurar los controladores de nuevo.

    Thank you very much, I have solved the problem thanks to you, I have exactly disconnected all the usb devices and started assetto and everything is perfect, thanks

    I disconnected all USB devices and it did not change a thing. I also tried VR and now I am getting crazy Frame time spikes also and it cannot hold 90FPS like it used to with my G2.

    I decided to try my old custom engine.ini file (i know you do not support this and it suggests to delete which I did) With the custom Engine.ini file, my 30 FPS came back and it performs like it used to.
  13. I formatted my ssd, installed everything again and the result was the same! I'm with 80/100fps, in 1440p single screen and high settings! Before I have 100/120 in 4k with some settings in epic! This is really frustrating...
    Any one have some idea???

    Before formatted ssd i'm on win10, now i'm in win11.

    Were you running custom engine.ini files before the update?
  15. No, every thing stock.

    What is your CPU Intel or AMD?
    WIN 11 has a noted performance hit for AMD chip sets. A fix is in the works but might take months as intel is in bed with Microsoft ..:rolleyes:
    If you're on intel Win 11 should be fine..

    Ahh i see your system specs above now , :eek: getting blind in my old age, we have the same gpu & see you have the Rizen , i have the R9 & have no loss of performance, using win10 .. i bet win11 is the culprit now .,, :( do a search on YouTube for win11 & amd chip sets loosing performance..,if it were me i would switch back to w10 until there is a fix from Microsoft..I almost made the switch until i got the news , its the one thing that stoped me from upgrading to 11 .. o_O:rolleyes:

    That performance is amazing, did you find your problem and get those frames back? I have been wondering how much performance a mire core CPU would bring over my 10600k, your performance sounds great.
  20. Juiced46

    I did get it back. I ended up loading my custom engine.ini file(not recommended by Kunos) that I was using prior to the update and I am back exactly where I was without using DLSS/FSR. I do however have a 3090. I used to have a 3080 and I noticed about a 15% increase in FPS when I switched to the 3090.
