Hey guys. I have some questions.

How do I switch my code from using GUM to GUM_VFPU. I tried a few things but it feels like it is not working (the reason I know is because if I do the matricies by hand & transform my verts, its faster then using GUM).

So can someone please tell me how to setup so I can use VFPU version of GUM?

First, change the library linking from:
-lpspgum
to:
-lpspvfpu -lpspgum_vfpu

And then change:
PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER)
to:
PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER|THREAD_ATTR_VFPU)
in your own code. That should be it.

Errr, Not sure if this makes a difference

"-lpspvfpu -lpspgum_vfpu" <- linking errors
"-lpspgum_vfpu -lpspvfpu" <- Compiles ok

Sorry just 1 more note. I now notice the difference but its not a huge improvement. :(
