Display / turn performance regression #22483
Game version: Tested build 6942 and 6951
Recently, moving over tiles with a lot of inventory on them produces noticeable slowdown, to the point that you can chain move commands and watch the game catch up for half a minute.
Similarly, when driving a vehicle, the display will lag behind the input to the point that collisions become inevitable. There is this strange across-turn delay where you can pull a vehicle around, complete the turn and hit numpad 5 a couple of times - watching the vehicle continue to turn.
It does this in both software and hardware rendering modes. The game has been handling massive inventories just fine a few dozen builds ago.
