Assetto Corsa Competizione: general troubleshooting

Q: Assetto Corsa Competizione crashes on startup
A: Please make sure your Windows Documents\Assetto Corsa Competizione folder and ALL subfolders and files included inside them are set to visible (not hidden). Make sure please you set hidden folders to be visible in the explorer to be able to verify.

Q: Can't find the executable (exe file) to run the game
A: It may happen that some antivirus/firewall software recognize executables as false positive. If your game executable is missing, please add your entire Steam directory to the exceptions in your antivirus software, then run a Steam integrity check or reinstall the game altogether.

Q: Can't assign controls / My controls don't work as expected
A: Delete the controls.json file located in your Windows Documents\Assetto Corsa Competizione\config folder, then reassign controls from scratch.

Q: Track-IR left/right works the opposite way
A: Just invert the "yaw" axis in your Track-IR profile.

Q: Poor performance in VR
A: Sometimes there are old configuration files that need to be reset. The safest way to do this is by renaming the %LOCALAPPDATA%\AC2 folder. Usually, this folder is hidden, to browse it:
  1. Open File Explorer/Windows Explorer;
  2. Type %LOCALAPPDATA% into the address bar and hit enter;
  3. Rename the AC2 folder
Q: My graphics settings appear to be blurry/wrong/not how it looks on screenshots by other users
A: Please provide a screenshot in the support forum so we can judge the situation, furthermore please specify your PC configuration and ACC settings in your forum signature.

Q: The virtual mirror is invisible even when turned on
A: The virtual mirror hides automatically when the player car is the only car on track, regardless of its visibility setting.

Q: Some car models are not available in certain game modes
A: When playing one of the official game modes, Assetto Corsa Competizione allows the player to choose cars according to the official entry lists of the Blancpain GT Series, as a result of which some entries might be available in one game mode (Endurance) but unavailable in another (Sprint). In custom racing modes, however, such as quick race and custom race weekend, the player is free to choose from and play against any car available in the game.

Q: The number of opponents is sometimes lower than the selection made in the UI
A: The available number of opponents can be set according to the selected track's capacity. However, in official game modes, the opponent field is constrained by the entries available in the official series. As a result, when playing an official Sprint Race weekend, the total number of opponents is likely to be somewhat lower than what the track capacity allows.

kernelbase.dll error on Windows 10

Solution from user Trystan34:

I somehow managed to fix the game. It finally launches!

I don't know which of the following actually events fixed it though. I think it may be the new account creation though.

I researched into "KERNELBASE.dll" error and found that users were experiencing issues due to account names or something.

The events that took place after researching:

  • Changed "Computer Name" (By default Windows 10 installed without asking me what I wanted the computers name to be)
  • I created a new User Account and made it an Administrative account and then restarted pc
  • Logged into the new account and installed Steam. (It started deleting cache files from the Steam install on my external HDD, I then installed Steam on C Drive)
  • Logged into Steam went to Assetto Corsa -> opened directory and and made AssettoCorsa.exe "Run as administrator" and then... IT LAUNCHED!
I then logged back into main Windows account and tried to run the game and it worked too. I then deleted the second Windows account and restarted pc. Once logged back in, tried running it once more and it worked again.

My progress and AC settings were deleted after update!

You can find automatic backups of the laptime database, livery selections and favourites in userdocs\Assetto Corsa\launcherdata\backups - if they were created they will be in directories with a "<DATE>-<TIME>" format, copy the contents of one of those dirs back in to the "userdocs\Assetto Corsa\launcherdata" directory.

We do not reset the documents folder automatically unless a major version change has occurred and then a version mismatch message will appear when you launch the game stating exactly what will occur and allowing you to not go through with the process giving you the chance to make a backup. That said, there was no major version change with this update.

What controls the version update is in launcher.ini:
[WINDOW]
VERSION=XX
The launcher.ini that is in the installation directory cfg folder has to match the version of the one in the userdocs folder - if that is not the case, you will get the version mismatch error.
#31

Can I play with a DirectX10 graphics card?

As reported in the "minimum requirements" on the Steam page, in the FAQ and on the official website, Assetto Corsa doesn't support DirectX 10.0 cards and will never do, due to technical factors.

Users with DIRECTX 10.0 video cards will not receive any support.
#10

User Interface too large!

If you cannot scroll down to the options button to go to "Options>General" and then check "Ignore Windows' display-scaling settings" (you need to restart the launcher for it to take effect), you can edit your "launcher.ini" found in "<UserDocuments>\Assetto Corsa\cfg" and add IGNOREDPI=1 under the [WINDOW] section.

My wheel is not centered or my pedals aren't registering their full amount of travel

Please try recalibrating your wheel using Window's calibration panel:
  • Go to control panel/devices and printers;
  • Right click on the device's icon and select "game controller settings";
  • In the window that appears click on the "properties" button (you might need to hold CTRL+SHIFT when you click on "properties" to get all the options in the following window) go to "settings" and then "calibrate..." .
This can happen when the driver keeps calibration data cached.

What are the differences between tyres compounds?

Road legal tyres
Street and semislicks are road legal compounds, used on the road. They wear out slightly. Their main problem is overheating, but after you have overheat them you can wait and start again, they can give similar grip even after lots of km's. In the end they will wear and lose grip totally.
Street tyres optimum temp: 75°C - 85°C but "easy" under and over those temps. Very easy to overheat after some laps on a circuit, especially on fast corners.
Semislicks: 75°C - 100°C but a bit less grip under that and overheat quite faster over that. They have more grip of course and can resist more fast laps, but do not like much abuse and drifting. They wear gradually and lose grip km after km.

GT2 slicks: The main difference of the GT2 cars is that manufacturers are actively developing tyres during the season and bring different compounds on the various tracks. We can't of course simulate specific compounds for specific tracks, but we offer 5 different compounds
SuperSoft: 90-105°C Don't like to be driven under or over that range. They wear out very fast
Soft : 90-105°C as Supersofts. they wear out fast
Medium: 85°C-105°C as supersofts over their range. They wear out in a linear gradual way
Hard: 80-100°C a tiny bit easier than supersoft outside their range but nothing too radical. They wear just a tiny bit after the initial laps and then stay quite stable for a long time until they start to lose lot's of grip
SuperHard: 80-100°C as Hards. They wear a tiny bit and stay stable for lot's of laps until they let go.

GT3 slicks. The biggest difference between GT2 and GT3 cars are their tyres. GT3 tyres are fixed for the whole season and the organization decides what tyres the car have to use. We provide 3 compounds that are not equivalent to their GT2 counterparts (worse).
Softs: 80-110°C . Wear VERY fast. We've been told that they were actually used only for a couple of times in qualifying.
Mediums: 75-105°C Wear linearly and predictably. all around tyre
Hard: 70-100°C Wear a tiny bit after a couple of laps and stay stable for a long sting. Not great grip but they are predictable and can be used in a wide variety of tracks and temperatures. Often "forced" by regulations on cars.

The hypercars slicks (Zonda R and 599XX) are a bit worse parents of the GT3 tyres. Let's say a generation behind. Rest of their characteristics is very similar to the GT3 tyres.

Vintage F1 67 Tyres
We provide just one compound for such tyres, although we learned there were actually different compounds. As a matter of fact, there is documentation reporting that Jim Clark choose the tyre that permit him to slide more for the race at Monza. Unfortunately there is not enough documentation for the compounds so for now we stick with just one compound. If anybody has more info regarding the matter, I'd be happy to discuss with it.
optimum range 50-90°C The tyres are good at low temps, and can withstand overheating pretty well. The tyre wear is gradual, you can expect to do a full race without problems, except if you overdrive and overheat them too much.

The tyre ranges are not perfect ranges but a min max range that you might not be able to understand a difference in tyre grip. Temperatures are also vary quite widely from straight to inside a turn, so optimally you need a tyre that stays at the lower end of the optimum temperature just before the braking zone and at the higher end of the optimum temperature at the exit of the turn. Not so easy to obtain.
In AC going outside the optimum range, doesn't mean the car will become undriveable. This characteristic is a double sword. You might think the car is good, but you're not driving on the optimum grip, so you'll lose time without understanding it. There's depth to be found and explored within the AC tyre model.

Another hint for tyre temperatures, as in real life, use more camber to heat faster a part of the tyre tread and then this dissipate to the rest of the tyre. More camber, more heat, less camber, less heat.
#15

I like to drive from hood/bonnet cam, but I'd like to hear interior sound. Is it possible?

At the moment, you can use a workaround.

When you are in the cockpit:

- open console (key "Home")
- write "set driverEye.z n" (without quotes, where n is a numeric value, i.e. 1. Pay attention, case sensitive!)
- press Enter

The point of view will move forward (if you put a positive number). Combine it with "set driverEye.x n" and "set driverEye.y n" to set the point of view according to your tastes.
#13

The game doesn't start at all when launched

  • Make sure the pre-requisite libraries have installed properly, you can find them by right-clicking on Assetto Corsa in Steam then "Local Files" -> "Browse Local Files...". Navigate to the "_commonredist" folder and run the setup for all the included redistributables. Pay attention to any error messages you might get and make sure no antivirus or such software blocks their installation. These are normally installed automatically on first run, but occassionally they will output errors which are not reported to you by Steam;
  • Use Steam's cache integrity check. Open your Steam games library, right click on Assetto Corsa and select "Properties". Click "local files" and then "verify integrity of Game cache";
  • Check your installed Windows updates. If you have the KB2670838 update, please uninstall it and try if the game starts properly.
#5

I get a crash while playing and a system reboot, don't know what causes it!

You're likely getting a blue screen and have windows set to auto-reboot on such (you can disable that to see the stop error by pressing Win-Break, go to "Advanced"->"Startup and Recovery Settings" and under "system failure" uncheck "Automatically restart").

Regardless if you disable autorestart or not, to see which driver component is causing it, you can get bluescreenview:
http://www.nirsoft.net/utils/blue_screen_view.html

It'll go through the minidumps windows have recorded and it'll report the component at fault.
#21

.NET 4.0 not installing and returns a 0xc8000222 error if invoked manually

You can find the installable by right-clicking on Assetto Corsa in Steam then "Local Files" -> "Browse Local Files..." and navigating to the _CommonRedist\DotNet\4.0 folder

Before installing .NET Framework 4.0 by running dotNetFx40_Full_x86_x64.exe:
  1. Press your Win key and type cmd, then right click on the result and select "run as administrator"
  2. Once in the command prompt type in command "net stop WuAuServ" to disable windows update
  3. Then press Win+R and type in "%windir%" at the pop-up window, it will take you to your windows installation folder
  4. Find the folder "SoftwareDistribution" and rename it to "SoftwareDistribution.old"
  5. Then, go back your previous command prompt and run the command "net start WuAuServ" to restart windows update
  6. Finally try again to install .NET Framework
#9

My wheel shakes on straights

Usually this issue is related to a too high Force Feedback gain parameters.
Assuming that your Windows profiler settings are at default, you can try the following methods:
  • Go in Options menu, then "Controls -> Advanced" page;
  • Lower the "gain" value;
  • Lower the FFB enhanced effects, especially the "road" one.
#17

Sound through my surround/5.1 speakers setup is "muffled" and the engine sound is low

Please be sure that you have selected the right playback device in windows and the proper audio device driver in the "Audio" app in game.
#12

Grey screen after introduction

  • Press F11. This will make the game's launcher exit full screen;
  • In some configurations it has been reported that setting "AssettoCorsa.exe" to run as administrator worked to by-pass this issue.
#4

Engine volume is too loud when playing in chase cam

This is related to 5.1/surround speakers setup. At the moment, volumes are balanced for 2.1/stereo speakers setup.

If you want, you can manually edit the file related to exterior audio.

- browse Assetto Corsa game folder -> content -> cars -> carmodel -> sfx
- open engine.ini (make a backup before editing)
- find this line: MIX_VOLUME=x.xx (where x is a numeric value)
- edit the value. The higher the number, the louder the exterior engine volume. Don't exceed too much or it will distort.
