i am still pretty convinced that tcl/tk is not the buster, so replacing
it by someting more performant will only give you little help.
the problem comes from how Pd(-core) communicates with the Pd-gui; and
that Pd(-core) needs a lot of calculation power to make Pd-gui draw
something nicely. unless this calculations are done on the Pd-gui side,
i see little chances that things will improve.
having said all that, i honestly do not understand how the matter of
CPU-hungry gop objects impose any problems on slow machines. you are
surely not saying, that you develop your patches for
iPod/wearables/P-100 andwhatelse with graphical objects.(?!)
personally i cannot imagine developing cpu-intensive patches on my
current machine, which is a by-now-rather-oldish amd64 x2 dual-core
(well, Pd cannot use more than 1 core anyhow) 4200+, with GOP enabled.
