Error message
Please check this article over at Steam Support and you’ll get troubleshooting suggestions depending on what you’re experiencing.

 

Minimum system requirements
Make sure your computer meets at least the minimum system requirements to run the game. If your system is not up to par with what's recommended, the graphics card might run into problems when loading the arenas, or your game could start to stutter.

 

 

Validate the Integrity of Game Files
Validating the integrity of your game files will compare the files on your computer with the ones on the Steam servers. If some files are different, they'll be changed/repaired accordingly but your saved data will not be affected. To do this, follow the next steps:

• Right-click on the game in the Steam library
• Select Properties
• Click on the local files tab
• Click the Verify integrity of game files button
• Allow the validation process to complete

Update your graphics card drivers
In order to run Rocket League, you must ensure that your computer has the current graphics drivers for your GPU model. The following links contain the most up-to-date drivers for each manufacturer:

• Intel
• Nvidia
• AMD

Running in Windowed Mode
If you, for example, get a black screen when starting the game, try this to check if your computer runs the game better in windowed mode:

• Open Steam
• Select Library tab
• Right-Click on Rocket League
• Select Properties
• Select Set Launch Options button
• On the command line type: –windowed
• Select OK
• Close Properties and launch game

Disable background applications
Background applications - especially programs which require bandwidth (chat clients, FTP programs, web browsers, etc) - may contribute to choppy game-play, a low frame rate, and other symptoms of lag or stutter. Unnecessary background applications can cause, slow performance, errors during the installation, issues with Audio/Video in the game, crashes, and other errors. Depending on which version of Windows you’re running, do the following in order to close the other applications you're currently running in the background:

• Press Windows key + R.
• Enter "msconfig" in the entry field and hit enter.
• Go to the Services tab, check the Hide All Microsoft Services checkbox and then hit the Disable All button.
• Select the Startup tab and open Task Manager.
• Disable all applications.
• Click the OK button and close the utility.
• Restart your computer so the steps take effect.

• Select the Compatibility tab
• Under Privilege Level, check Run this program as an administrator
• Click Apply/OK

• Right-click on Rocket League in the Steam library
• Select Properties
• Click Set Launch Options, found under the General tab
• Type in: -autoconfig
• Click Ok

Reinstall/Repair DirectX 9.0
Rocket League runs using DirectX 9.0; in some rare instances, the game may have trouble finding files in DirectX due to missing components or a corrupt install. In order to remedy these problems, follow the links to Microsoft’s support website here:

• DirectX End-User Runtime Web Installer
• DirectX 9.0c End-User Runtime

Download and Install Microsoft C++ Packages
From the Microsoft website: The Microsoft Visual C++ 2010 SP1 Redistributable Package installs runtime components of Visual C++ Libraries required to run applications developed with Visual C++ 2010. Rocket League requires components found within these packages, they can be downloaded here:

• Microsoft Visual C++ 2010 SP1 Redistributable Package (x64)
• Microsoft Visual C++ 2010 SP1 Redistributable Package (x86)

**As of the Clubs Update on August 29, 2018, Rocket League will require the Visual C++ 2015 Redistributable. This should be downloaded and installed through Steam automatically, but can also be downloaded here:

• Microsoft Visual C++ 2015 Redistributable Update 3 RC
