Using Wacom in GIMP Performance Issues
m@
photoshop or linux CinePaint. When I am drawing in GIMP it seems to
hang or glitch, I dont know what the proper word is but it seems to
not be as good as CinePaint when I am drawing, I have adjusted the
pressure settings to all sorts of values requested by people and the
manufacture, and the pressure changes but thats not the problem. It's
like you draw a few circles and about half way through the circle it
skips or doesnt draw it, like there isn't a good connection to the pen
or something it's frustrating cause i love GIMP and I dont want to use
windows lol.
Anybody have any ideas what settings I could adjust in GIMP maybe its
a GIMP perofrmance issue? Again it doesnt do this in photoshop on
windows, and it doesnt do it in other Linux drawing programs just GIMP
so i figure its a GIMP issue.
Here are my specs.
I have a wacom Graphire4 CTE-440, and GIMP 2.2.11

In the option settings of the Gimp tool that you're using, is the "Fade
Out" checkbox checked? If so, uncheck it. What you described seems to be
the "fade out" effect in Gimp.
Let us know if that's the problem.

help!
Also I would like to say that if I had to compare it to like a video
game, it's almost like periodically I have really low FPS.
I just wish I could demonstrate it some how.
BTW I have an ATI 9600 128MB Graphics Card, using the ATI Official
drivers.

I don't have a good theory as to what is causing the problem, but I tend
to think that your graphics card and its driver are not the problem. To
me, the symptoms you described seem to suggest that for some reason,
your tablet is generating events faster than they can be handled. Maybe
you can try, as an experiment, to repeat what you did with the system as
lightly loaded as possible. Close all unnecessary programs, stop all
unnecessary processes, and try to draw slowly. See if you still have the
same problem. Hopefully that will at least give you better insight into
the nature of the problem.
I found these pages on the web:
http://www.shallowsky.com/linux/wacom.html
http://linuxwacom.sourceforge.net/index.php/main
I don't know if they will be of any help, but good luck.

Also I am going to try it on another computer next week, I'll post my
results soon as I get them.
Thanks again Ricky!

Thank's for all your support.

Glad to hear that you found a workaround, albeit an imperfect one.
