Re: GLX acceleration

Alexander:

I believe the problem to be with the new xorg files, but there are quite
a few and I don't have time to reinstall them all.  I assume I'll just
wait until the next update, but I hope the maintainers will at least
keep this potential problem in mind.

I have this CPU problem under xterm or rxvt, not only with dired,
but also with ispell under mutt in these windows.  I do not have these
problems at all (using dired or ispell under mutt) under the standard
Cygwin console window (no xorg depdendence).

I note that dired using ncurses, ans perhaos ispell under mutt might too?
Could there be some kind of new conflict with xorg utiltiies?  I have all
my "Curr" Cygwin files from mirrors.rcn.net up to date (omitting only
"setup" -- which always seems to revert to Skip when downloaded -- and
"gcc-testsuite").

Thanks for the info on glxgears.

glxgears shows the fps and has a dramatic speedup.

Have you tried downgrading cygwin? Are the problems still present?
