To hide network latency, MP turns send commands not for the next turn but N turns after that (introduced inc684c211a2). Further, MP turn length was increased to 500ms compared to 200ms SP turns (introduced in6a15b78c98). Unfortunately, increasing MP turn length has negative consequences: - makes pathfinding/unit motion much worse & unit behaviour worse in general. - makes the game more 'lag-spikey', since computations are done less often, but thus then can take more time. This diff essentially reverts6a15b78c98, instead increasing COMMAND_DELAY from 2 to 4 in MP. This: - Reduces the 'inherent command lag' in MP from 1000ms to 800ms - Increases the lag range at which MP will run smoothtly from 500ms to 600ms - makes SP and MP turns behave identically again, removing the hindrances described above. As a side effect, single-player was not actually using COMMAND_DELAY, this is now done (can be used to simulate MP command lag). Refs #3752 Differential Revision: https://code.wildfiregames.com/D3275 This was SVN commit r25001.
