Changeset 1691 for code/branches/gui/src/orxonox/gamestates

Timestamp:

Message:

• Server GameState works. But the Client has problems that don't seem to be related to GameStates.
• added command line argument: limitToCPU for windows at the moment. 0 disables limitations, 1 limits to core 1, 2 to core 2, etc. if possible.
