Changing mathlibs is it really usefull?

IIRC, the math libraries are used in machines without math co-processors (68881 and 68882).  I don't believe Workbench's GUI requires much number crunching.  Applications like Digital Universe, Distant Suns, Vista Pro, ray tracers, etc are performance-dependent upon the quality of the libraries or co-processor.

It seems back in my A500 days, some of the enhansed and optimized math libraries on Aminet made a noticable difference.

Someone will correct me if I'm wrong.  The 68040 and 68060 CPUs have FPUs (math co-processor) built into their chip.  The 68020 and 68030 were designed to be supplimented by a seperate math co-processor (68881 or 68882), or, could run the libraries.

The 68000 and 68010 are compatible with math co-processors, I think, but were never expected to have FPUs available.  I think code for these CPUs usually require the libraries.
