Vulkan! Powering AAA Experiences on Android
summary
Vulkan on Android gives concrete wins: real projects see about 20% FPS uplift (Fortnite on Note 9), pipeline caching cuts level load from ~5.5s to 0.2s, and subpass use yields a ~6% GPU speedup while saving ~700 MB bandwidth and dropping GPU idle from 1.0ms to 0.15ms. Practical tools are RenderDoc, Streamline and the on-device GPU Watch. ASTC textures and 64-bit builds are recommended; validation layers catch common layout and descriptor mistakes.
