Frequently Asked Questions
Download the external dependencies and extract them into the main OpenRA folder.
No. OpenRA is completely standalone. When you run the game for the first time it will download a minimal copy of the game files that it needs to run or rip the game-files from the CD now.
Maybe. EA have released both C&C and RA as freeware. The files are already available for free; we are saving EA bandwidth by hosting only the ~15MB of files that we need to run the game, instead of making everyone download the 700MB game ISO CD image.
See Branches and Releases for more information about the release process.
#Nobody can join my online game! For others to join your game, you must forward a port in your router for them to connect to. By default, OpenRA uses TCP port 1234. This can be be configured in the Create Server dialog. If you have a router that supports Universal Plug and Play tick the allow UPnP checkbox. Please keep in mind that you also need to allow connections in your software firewall.
#My game just crashed! We're sorry to hear that
Telling us "my game crashed, you suck" is not helpful. Please follow the steps below to collect the basic information we need to help you. Game Version: You can see this on the main menu Crash Log: Depending on your operating system, this will be in a different location
- Windows:
My Documents\OpenRA\Logs\exception.log - Mac OSX:
~/Library/Application Support/OpenRA/Logs/exception.log - Linux:
~/.openra/Logs/exception.log
Before you post this information on the forum or IRC, please READ THE FIRST LINE OF THE EXCEPTION LOG and CHECK THE COMMON ISSUES BELOW. If you have a problem that is not mentioned here, please let us know on http://bugs.open-ra.org.
If the exception mentions a out of sync, please also post sync.log, which you will find in the same directory, and get everyone else who was playing the game to post it, too. The sync log is only useful if we have multiple players submit their log. You can use http://www.quickdiff.com/ to find the part that caused the desync exception.
#"No Valid Techniques" or "Unsupported GPU" This error occurs if the game cannot start OpenGL. This could occur for a number of reasons, depending on your operating system and graphics card
- You need the most up to date graphics drivers, EXCEPT if you have an ATI card. In particular, the Intel drivers that are bundled with Windows ("Vendor: Microsoft Corporation") do not include any OpenGL support. See your graphics card manufacturer website to download the latest drivers.
- You have an old graphics card that doesn't support OpenRA. Although OpenRA may look like an old game, we make use of modern hardware capabilities. We require Shader Model 2.0, which means that nothing before about 2004, and some more recent cards WILL NOT WORK.
- Compiz causes issues with OpenGL applications on Linux. This is a bug in Compiz itself, which they appear to have no interest in fixing. You will need to disable Compiz before running OpenRA.
If you are sure that none of the above issues apply, create a forum thread or see us on IRC.
This error occurs can occur if you have outdated graphics drivers under Windows. See the point above on updating them.
If your mouse cursor, fog or icons do look corrupted try using the Cg Toolkit renderer. Start OpenRA.Game.exe with the command line parameter Graphics.Renderer=Cg or change your Settings. It turned out that this was a bug in the GL renderer which has been fixed in release-20121019.
CnC is unplayable and in RA trees, submarines, shock troopers, tesla tanks, badger bombers and all ballistic stuff like missiles, cannon shells ... won't render properly. Instead there are random animations of stuff being blown up or infantry replacing trees. The badger bomber being replaced with 4 burning infantry...
Known issue with 64-bit Catalyst 10.8 driver. Try downgrading to 10.7 to fix the problem.
OpenRA is a work in progress, and we are doing our best to improve performance. To help us fix this, we will need some information from you.
- Enable the performance graph (from the main menu → Settings → Debug → Show Performance Information) and note your average Tick and Render times in a game.
- Your perf.log from the logs directory above
- Your computer specs (CPU and Graphics card are most important).
Please make a forum post or a bug report with the above information.
Please report yours to http://bugs.open-ra.org with the following crucial details:
- What you were doing when something broke
- What you expected to happen
- What actually happened
- If it's a crash, the contents of exception.log.
No. While there are currently no checks in place for this, it is advised that you only run identical versions of the game when playing multi-player games. While the network protocol may not change, differences in unit behavior between versions can cause desynchronization between clients.
This depends on:
- Voxel support
- Isometry
- SHP file format changes (see https://github.com/katzsmile/OpenRA)
which is a huge lot of work and currently not on the agenda. You patches are welcome however.
Get involved. There are a few ways you can do this.
- Fork the repository and start hacking. Fix that issue that's been annoying you.
- Report bugs and crashes at the bug tracker
- Join the community. The forums are a great place for future mod discussions and game-play ideas.
