Since QL normally forces players to choose between 3 maps when the current game ends it seems like an obvious optimization is to preload all those maps so that the map load time is reduced to zero when a map is ultimately chosen.

I think this is reasonable because there is already a relatively large amount of time for players to choose maps (10s?) which should be plenty to load all 3 maps.

Then once the final map is chosen the 2 loaded maps that were not chosen can simply be thrown away.

I think this would make for a smoother experience.
