Funny thing is it runs nicely on my now ancient 900mhz/512mb AMD Homebrew computer. I keep seeing people say it is slow on their modern super computers.
Once it's running it's generally fine for me. The long startup time is a little annoying. Macromedia products are just as bad in that regard, and it's one big reason why I tend to just leave everything running (except Macromedia Fireworks which uses a few % of my CPU even when it's idle).
Maybe it is just that I normally only have one or two aps open at a time.
Gee, is that all? :) I have two user accounts logged in with about half a dozen apps open on each.
I have been playing with a 112mb/20mp file and it has been fine.
PS gets slower with larger files, as you might expect. 350Mb files can take a while to process. The new "expanded pixels" preview mode (or whatever they called it) was quite a good idea. I think the plugin for my film scanner causes PS to misbehave a bit - it seems much more responsive if I save my file immediately after scanning, then quit & restart Photoshop and reload the file. I should get around to trying the scanner plugin stand-alone.
BTW I have never ever seen Photoshop de-allocate any memory. I've seen PS using over 1Gb of memory with no files open!
I've found that the healing brush tool is horrible with large files (it's quick up to 50Mb, difficult above 100Mb) but the new spot healing brush is a bit better. Not that it matters - I went back to using the clone tool as the healing brush and patch tools didn't behave well with the grain patterns I get with high-res film scans.
Oh another thing I do is once I have finish with a layer I tend to collapse it and so usually only have 2 or 3 layers going a once. I guess it is just a legacy of mine from older non-multitasking OS, and 48K ram.
Layers can slow things down a bit when the preview is updating. I've been working on a business card that has about 20 vector, raster and adjustment layers. I should get around to getting that printed...
Having said that I've been somewhat afraid of trying to apply layers to my larger files. I must find out how well they work.
