I have a patch PR#100 which allows the display and physics/movement to run at 60fps, while the behavior update remains at 30 ticks per second. It would be useful if behavior could also run at higher rates:

However, some game internals are still tied to 30 ticks per second, some XML data fields are specified in ticks while others are in (game) seconds. So changing the tick rate will probably break backward compatibility. Would this be worth considering for a v2.0 release?
