I have about 100 moving sprites on my project. I had some performance problems that bothered me and I figured out it was the brightess effect I added on them that was slowing down my game.
While trying to fix that I learned that a brightness effect with the default value of 100, which make no visual change, uses a lot of CPU too, which is kind of surprising but whatever.
So I was wondering how I can know how much CPU intensive are the different effects ? And is it possible to achieve an effect similar to brightness, but with better performances ?
