I have 2 sprites on screen, each has 17 frames,animation speed of both is set to 0. I noticed that these 2 sprites really affect the performance of the phone (WP8). When I have them on screen, I get 19 ~ 20 FPS. When I remove the two, I get ~ 50 - 60 FPS. That's a huge different.
Is sprite with 17 frames counted as 17 sprites on screen?
