I noticed that "Destination out" blend mode with "Force own textures=yes" set on the layer costs about 10-15 fps in performance drop on my older mobile phone.
I'm going to disable this blend mode on slower devices and use an alternative (less nice looking) effect.
So I have 2 questions:
1. What's the best way to measure performance? I'm thinking when the level starts, collect fps on every tick for about 5 seconds, then calculate the average fps. If average fps<30, then disable blend mode.
Is there a better or more reliable way?
2. Is is possible to get masking effect without the "Force own textures" setting?
