Unreal Engine developers can take advantage of SER within the NVIDIA branch of Unreal Engine (NvRTX). The shader changes can be more intensive due to assumptions in the original code (functions using macros to permute behaviors rather than arguments). Saved binaries, on the other hand, only need to be replaced when the compiler portion of the driver is updated. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform.

Near field and far field in lumen correspond with different sections of the TLAS for objects close to the camera, and objects far away from the camera respectively. Users/players should then consume the cache by enabling r.UseShaderCaching and r.UseShaderPredraw. New AMD drivers tend to keep shader cache off. Execution divergence occurs when different threads execute different shaders or branches within a shader. Furthermore, the cache files become invalid every time a new driver is installed. Other games seem to cache their stuff on their own files, so countless driver changes don't even affect them one bit and other games may stutter a few seconds when you start them and then they just settle down just fine.

SER is a performance optimization that unlocks the potential for better ray and memory coherency in ray tracing shaders, and thus increased shading efficiency. I have around 10gb of shader cache just in steam. While the ray tracing passes used in Lumen global illumination do not run a divergent hit shader, they still benefit from the mechanisms provided by SER.
