re:normal maps
disabling them only got me a couple more FPS, and even turning off the backbuffer copies you have in the camera only got me up to 90. an unlit 2d scene with just the player and its somehow at 90 fps. im not even trying to be mean i just genuinely have no idea how you managed this. it might be some shaders you have somewhere, but there are literally dozens of them and i dont have time to go through them all. good luck lol
