\item[\texttt{MTS\_SSE}]Activate optimized SSE routines.
\item[\texttt{MTS\_HAS\_COHERENT\_RT}]Include coherent ray tracing support (depends on \texttt{MTS\_SSE}).
\item[\texttt{MTS\_DEBUG\_FP}]Generated NaNs will cause floating point exceptions, which can be caught in a debugger. Warning: This is slow!
\item[\texttt{MTS\_GUI\_SOFTWARE\_FALLBACK}]Forces the GUI to use a software
fallback mode, which is considerably slower and removes the realtime preview.
This is useful when running the interface on a remote machine
accessed via the Remote Desktop Protocol (RDP).
