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.

    I keep tumbling on this argument about DLDSR and once again I say it's incorrect: DLDSR allows to have some more resolutions to choose from within game video options, it doesn’t mean you're bond to have to use them or use the same resolution in every game.
    You can have one game video options set to run with native monitor resolution while another can be set to run with a DLSR resolution. Just as simple as that.

    Okay, and in ACC I set the resolution to 3840 x 2160?
    How about SRWE then? Because now my center screen isn't perfectly centered. Do you use SRWE and DLDSR? If so, you can please send me your settings? :)

    True, except it doesn't work 100% reliably in ACC unless you set desktop res to match DLDSR. May be it was just my setup but other people reported some oddities as well. Other titles, it's not a problem, go figure.

    You just put the files in the wrong folders.

    dlsstweaks.ini and nvngx.dll have to be in folder "Assetto Corsa Competizione\AC2\Binaries\Win64"

    The nvngx_dlss.dll in version 3.x has to be in the "Assetto Corsa Competizione\AC2\Plugins\DLSS\Binaries\ThirdParty\Win64"
    You still had the default 2.2.15 there in your screenshot.

    I got all the right files in the correct folder. But the overlay still doesn't tell me it's using DLAA.
    Still showing the DLSS version.

    ForceDLAA should be false and the DLSSQualityLevels enabled: true
    Check your dlsstweaks.ini

    If this does not work, follow the guide in the dlsstweaks.ini

    DLSSQuality levels is for overriding percentage for standard DLSS, for DLAA you need to set
    ForceDLAA=true
    and optionally
    DLAA=F instead of 'Default'

    This works like a clock in my system.

    You don't have to, the Quality = 1.00 set in the ini is DLAA.

    That should work too if you want to keep regular DLSS along with DLAA, but this is not default value, this is what in original ini file, looks like you changed yours.

    Code:
    [DLSSQualityLevels]
; DLSSQualityLevels: allows overriding the ratios that DLSS uses for each quality level
;  Note that enabling this section will disable the ForceDLAA setting above
Enable = false

; Ratios/multipliers applied to each axis of screen resolution
; Set to 1.0 to force this quality level to use full resolution (ie. DLAA)
; Values are limited to range 0.0 - 1.0
UltraPerformance = 0.33333334
Performance = 0.5
Balanced = 0.58
Quality = 0.66666667

; UltraQuality: certain games may allow this to be chosen if uncommented (remove the ";" at the start) and set to non-zero value
;  Very few titles actually allow using this though, but a small few may show an option for it once enabled, giving you an extra DLSS level to choose from
;UltraQuality = 0.77
    Plus I believe your setting for preset might not work, and you need to set Quality to F, not DLAA.

    Code:
    DLAA = F
Quality = Default
Balanced = Default
Performance = Default
UltraPerformance = Default
    Played few hours yesterday with DLAA, even combining it with 1.75 DLDSR, still 2.25 DLDSR + DLSS Quality produces the best results.

    2560,1440 -> 2560,1440
    where exactly is the issue? you are already running at native resolution.


    In case you change the preset, preset F has stronger antialiasing and small details are a bit more blurry in the distance.
