Thanks for trying out 0 A.D. and coming here to report your problem. As the game is still in alpha releases there are still many things we need to do. Many of these we know already, so when you provide feedback we would ask you to focus on some of the other points that could be improved.
There is a neat table of planned features at http://trac.wildfire...ayFeatureStatus so you can tell what we are planning to add.
This is a common complaint, and with good reason. The game does not run as fast as we would like. Late in the game you will probably experience some lag, this is caused by a mixture of things, AI and pathfinding are big ones. The problem is worse on island maps and with multiple AI players.
One thing that can be helpful is giving us the profiler information. This automatically generated information is useful for working out where the lag is coming from. If you hit Shift-F11 this will be dumped into a file (location given at the top of the screen). Please upload these data to our forums to help us solve the problem. Thanks!
There's a sound bug!
The sound system has been completely rewritten for Alpha 11. It was well tested, but you may find problems like bad sound or errors. Please report these on Trac or in the Bug Reports forum with as much information as possible including logs.
Retina display issues on OS X
If you find the game won't run correctly in fullscreen on OS X with a retina display, use the config file to start the game in windowed mode as a workaround, see the settings page of the game manual for details.
Some units glide around or don't drop to the ground when killed. We have an animator who is working away at making pretty animations. More animators are invited to help with this task.
Units Can't Attack When Chasing
There is a problem in the code where units decide to attack, then the chased enemy gets out of range before the attack hits so it is aborted, so in effect any units chasing each other won't be able to deal damage.
Greyed out/disabled menu items
Some menu items can't be clicked on, this is because those features aren't yet implemented.
Units don't fight in formation
Can't run two instances of the game simultaneously on Windows
Using Ctrl+Alt+Delete in Windows while the game is loading may cause a crash
No one can join my game!
Currently, only routers with UPnP support or routers that have been properly port fowarded are able to host.
My 1v1 duel wasn't rated.
There's an issue with keep-alive packets not being sent to the server. This issue should have been fixed in the developmental version and for Alpha 16 and subsequent releases.
I was disconnected from the lobby...
This is usually caused by the timeout mentioned in the issue above or by a moderator kicking you for abusive behaivor or inappropriate/vulgar chats.
Out of memory errors using Aegis Bot

AI Doesn't Know how to Build Ships
There may be errors loading a saved game with AIs. Rejoining a multiplayer game with AIs is not supported yet.
"You should use multiple threads"
0 A.D. was designed when multiple cores were not yet common, and it would take too much work to program the game to get it to use multi-core processors efficiently. Still, it can be good to have multiple cores, because they may be available to other programs running while you play 0 A.D.
"You should use Kickstarter, Indiegogo, etc."
We have an Indiegogo campaign now! Visit the official page to learn more about our goals and how you can help support 0 A.D.
