I've been working on further optimizing Spine performance lately. For Spine files with a lot of vertices on mid-range devices with moderate performance, using SIMD significantly optimizes CPU usage, reducing it by about 10 to 20%. However, for files with a typical vertex count on high-end flagship devices, the optimization gains from SIMD aren't as pronounced, only reducing CPU usage by about 4%.
