Hi, I will have a look at the warnings.

Notice that the fast dynamic cast fallbacks to regular dynamic cast on when not compiling with MSVC, so you will not see any performance benefits.

The warnings are safe to ignore, just compile with -Wbackslash-newline-escape as the compiler output suggested.

I will close this PR since its unclear for me what you are asking
