Description

D3D11Commands.cpp is doing FName resolutions in the critical fast path. This looks to be a regression from the memory freezing refactor.

Steps to Reproduce

Compare editor runtime performance between 4.23 and 4.26 (unsure if this manifests in intermediate versions). 4.26 is slower on the render thread.
