A Quick Look Inside Your Games: GPUWatch Tutorial + GameEngine Talk
summary
GPUWatch (GPWatch) runs on Galaxy devices without installation and shows real-time on-screen FPS, CPU/GPU usage, per-frame GPU captures and render-pass timelines for Vulkan and OpenGL ES with no root required. Captured frames show timings (example frame = 17.8 ms), a single pass removal saved ~30 ms in one project and combined fixes produced up to 10x faster render times; measured CPU-side Vulkan wins were 20-40% faster than OpenGL ES. Overhead is minimal; Android P will include GPWatch and roadmap adds frame-drop, memory and bottleneck detection.
