Thank you Superku I will follow your suggestion and try with second variable. Can you please explain why you use so low fps_min? In my game I use fps_min 50 and fps_max 60, is it okay? I think it's better if the game goes slow, but to comes to big frames skipping. I control a lot of things in the game through animation, and I fear that my game would not work well on weaker PC. I'm not sure that fps_min really can help here.
