PD runs in native 64bit mode just fine on my turion64
with gentoo.
you clearly didnt use it. besides launch it and say 'oh, it runs fine'.
i guess it is possible to use despite all the math errors and without the ability to store
and recall audio in RAM. but i dont consider that usable.
So in my point the argument "some things
don't (yet) run on 64bit"
doesn't count a cent. :-)
i gues PD, SC, and Chuck dont count a cent in your world. despite their 'free'
status. i place some value on them :)
