I have a roguelike game: it's 2D, uses pixelart sprites and is written entirely using blits to the UI in unity. Because I heard that 5,2 was going to give better performance through better batching I took an fps count by turning off vsync in the quality settings and running the game in the unity editor. I was getting about 330 fps. After upgrading to 5.2 I tried it again and was only getting 130-160! Is there something I might have missed or has UI performance actually got worse in 5.2? edit: I admit though, I was using just the start button in unity itself, I wasn't using "build and run". I'm trying to test the game under both unity versions right now but I'm suffering from another problem: that 5,2 doesn't seem to go full screen to 1280x720 anymore but stays in desktop res.
