273 greatly reduces performance on me when many shadow caster object are on screen. I'm not able to reproduce the bug, but there must be something making the shadow behaviour more CPU intensive than 272.
Back in 272 i could zoom out the game and enjoy 60 fps, now with 273 it's 20 fps! If i disable shadows, it goes back to 60.
If someone is able to reproduce the issue, please do so, I'm failing to do so with a new game, since the problem could be ause by a specific position of the shadows on or off the screen..
