r.ShaderCompiler.TooLongIOThresholdSeconds

#Overview

name: r.ShaderCompiler.TooLongIOThresholdSeconds

This variable is created as a Console Variable (cvar).

• type: Var
• help: By default, task files for SCW will be read/written sequentially, but if we ever spend more than this time (0.3s by default) doing that, we\'ll switch to parallel.We don\'t default to parallel writes as it increases the CPU overhead from the shader compiler.

It is referenced in 1 C++ source file.
