Hi Marek. Basically SkeletonGraphic and SkeletonAnimation will not differ much in terms of any "bad general overhead", however it might be interesting to do some stress tests on your target device. For example a quick test of 55 animated Raptor skeletons resulted in ₇.3ms per frame according to the Stats view, whereas the same number of SkeletonGraphic objects results in ₈.0ms per frame on my local PC. While the fps is actually a bit worse at SkeletonGraphic, it displays Batches: 3, Set pass calls: 3, while with SkeletonAnimation it displays Batches: 55, Set pass calls: 3. That is under the assumption that you place all SkeletonGraphic objects under one Canvas. If every Raptor has it's own Canvas, Batches will be increased to 55, duration per frame to about ₉.0ms.

So in short: it will most likely depend on your target device and your setup, and the best way will be to do some short testing on-device. Only measurement will tell the truth .
