This article discusses several approaches to optimize PSO hitches in UE5, briefly introduces their implementation mechanisms, pros and cons, and compares their performance. 1. Background

We know that changing GPU rendering states during DrawCalls incurs overhead. Modern graphics APIs (D3D12, Vulkan, Metal) provide PSO mechanisms to reduce the overhead of

This article provides a brief overview of UE's shader compilation, loading, cooking, and serialization mechanisms, highlighting the key logical components. For brevity, the
