We untangle the Unreal string types, and outline how to choose the one you need!

During an optimisation pass on an internal project we spotted a few areas in UE4 deserialization code that could be hardened up. This post presents those fixes.

ToString() is one of the most commonly called functions in UE4 - certainly across the editor, the content cooker and such. Here we take a look at it and make it over twice as fast

Here we present several small code fixes and improvements in a nice little package

We use the debugger's disassembly view to look at FPaths::IsRelative() after it shows up in our profiling tests. Then we optimize it

We found CreateExportHash() was showing up in profiling the cooker - so we optimized it. Our findings and changes are presented here

We present an optimization that removes a significant amount of memory churn from the animation code
