I have installed Pixel Bender toolkit and plugin into
Photoshop CS4 running on my Mac G5 under OS X 10.4.11. The installs
all completed fine without error. But every time I go to run a
filter I get the message that the number of pixels exceeds the
hardware capabilities of my GPU if the image is over 2000 pixels
wide. On my newer Intel laptop I can work on images up to 4000
pixels wide. So 2 questions. If I upgraded the graphics card on my
G5 could I work on images up to 4000 pixels wide? 2nd question: are
there any graphics cards which would enable working on images over
4000 pixels wide?
Yeah, this is a limitation of your video card. A higher-end
or newer card (like the one in your laptop) doesn't have the same
limitations. I'm not sure what your options are for upgrading your
machine, but I know that there aren't too many (as the proud owner
of a G5 myself)...
