Vulkanized: Mobile Game Optimization Techniques
summary
Practical Vulkan tips and measured wins: implement generated unique IDs for objects to avoid handle reuse bugs and cheap garbage work; persist and pre-load a pipeline cache pre-load/save to avoid IO stutters and note switching pipeline compilation to all cores doubled pipeline build speed on a Galaxy S8; allocate big buffers and a ring buffer + fences for per-frame uniform data and cache descriptor sets or use dynamic uniform buffers to avoid per-draw updates; replace multi-pass deferred shading with subpasses for an observed 8× speedup and 14% GPU time drop.
