summary

A Visual Studio feature that gives optimized builds full debugability by building the project twice and selectively deoptimizing only the frames you inspect, showing locals and enabling reliable stepping and set-next-statement. Available in Visual Studio 17.14 Preview 2 and integrated with Unreal Engine 5.6, FastBuild 1.15 and IncrediBuild 1024, it marks frames with a deoptimized tag and lets you deoptimize on next entry. Works x64 only, excludes LTO/PGO/ICF/incremental linking, and increases output size and some build time while cutting rebuild cycles.
