Setting the time rate in game (on the battle screen) up to about 1.3 or 1.4 makes the unit animation look much more realistic, as opposed to moving under water. Hold shift and click the time compression arrow on the battle minimap and it will go up in increments of 0.1 instead of jumping from 1.0 to 2.0 then 6.0
It will revert back to 1.0 when scrolling on the map, but as soon as you stop it'll jump back to whatever you set it to. This works with M2TW vanilla and other mods as well, it drastically improves the fun of watching battles IMO.
I posted this a while ago but only in the EB2 forum, answered someone's post about it here earlier today, and just thought I'd drop this here for anyone who didn't know.
Makes M2 battles 1,000,000% more fun to watch up close, no more "moving underwater" weird slowish-mo fighting.
