The discussion focuses on the complexities and challenges of shader compilation, particularly in the context of various GPU APIs and binding models. Users highlighted issues with existing solutions like spirv-cross, which can lead to lossy translations, and the difficulties posed by varying support across platforms. There’s a call for better management of shader compilation processes by game developers to minimize wait times for users. The emergence of projects like blade and BGFX, which handle cross-platform shader code with clever techniques, illustrates ongoing innovation in this space. The conversation also critiques how some platforms maintain outdated practices that hinder progress towards more streamlined shader compilation processes.
