Painting in Photoshop 7 is choppy lately.

I've been using photoshop 7 on my 1.25dp G4 using Mac os 9.2.2 and a Wacom Cintiq. When I first installed everything it seemed to paint smoothly, but now it seems very choppy in the painting animation (it seems to also be adding corner bits to my curves). I've tried reinstalling the wacom drivers, rebuilding the desktop, zapping pram, and running techtool pro. I haven't reinstalled the system yet, as I don't know if that'll be necessary.

I'd appreciate any ideas you all have, thanks in advance.

JUST A THOUGHT...

How much RAM do you have? OS9 can use up to 1.5 Gigs and with Photoshop, you can set it to use around 85% of it without destabilizing the system. Also, if you have a smaller 7,200 RMP Hard-drive laying around, might be good to install it just for Photoshop scratch - this is especially important in OS9 where cooperative multitasking can jam-up one app, for a small function-call in another. A separate scratch can be more independent than the boot volume that is constantly under Finder control. Lastly, OS9 does fragment and must be defragged from time to time. Norton Utilities 6 ( http://macintoshgarden.org/apps/norton-utilities-6 ) has a great defragger that might be a big help.

If your above G4 is the same as what you are using in the other thread you began here, then maybe this is where the problem lies.

Multiple graphics cards with conflicting drivers can cause problems with graphics processor accelerated features in Photoshop.

For best results, connect two (or more) monitors into one graphics card.

If you have to use more than one graphics card, make sure that they are the same make and model. Otherwise, crashes and other problems can occur in Photoshop.

Just a possibility is all...

Except Photoshop in OS9 doesn't use any graphics acceleration - you have to go clear up to CS4 to even find that option.

Given that he has 3 display cards, one mismatching (and conflicting), + 3 monitors, one connected to each card that he's interfacing to Photoshop via a Wacom Cintiq...

- I'm assuming he'll have tool pallets etc, distributed over separate monitors to maximize his main view/working area. So I think there is a very likely connection there, as to his lags and other hiccups...

In his other thread, MacTouch's sensible suggestion there may prove useful for him to try.

Could be - hopefully it will fix it. Most paint programs use vector (especially in OS9) because it is much easier on memory. Painting in Photoshop in raster with actual pixels is very heavy on the system.

No they are 2 different G4's. The 533Mhz G4 has 3 monitors and is at home. I have the 1.25ghz DP at work. (I keep the second G4 at home as a backup in case my work machine goes down)

The 1.25 ghz G4 has 1 graphics card and 1 cintiq 18sx.

Ill have to try the scratch drive idea.

Also any ideas on alternate software that may work better?

Good thinking though

Cool thanks for the suggestions, I'll try them all. Do you recommend painter 6 over painter 7?

Also, I tried to increase the memory allocation of photoshop and it totally smoothed painting up for me. I used to have it increased, but now I remember that I zapped PRAM a few months ago, I assume that must have reset it possibly. Thanks for the help and suggestions.

To me Painter 7 felt a bit needlessly heavy and sluggish, but results will very of course.

Ah, then what Maximum R.I.S.C. say's in his 1st post makes a lot of good sense. Especially with regards to having a separate scratch disk, not on the primary boot drive.

Also quit applications that you don't need to use if they are running in the background.
Another thing to look for is when doing loads of Photoshop work, to go "Edit" menu, "Purge" and clear your histories. Histories can cause Ps to become sluggish if there is a huge amount of information held in memory. You do lose your histories for that session, so save any work before purging.

On newer systems running OSX, Windows or Linux, I have to say Inkscape (inkscape.org) is really hard to beat (and it's free).

Here couple done in it (with a bit of help from Photoshop).
