“Could not complete the Export command because there is not enough memory (RAM).”

I got this when merely trying to export to the web a simple and small image.

I have 8 gigs of RAM, and CS4 never had this problem.

I won’t detail the screw-with-the-plugins-for-hours agony or any of the rest of the trauma, and I’ll skip to the chase:

the 32-bit version of PS CS5 no longer recognizes 3072 Megs of RAM on an 8-GB machine, and instead recognizes only 2.1 gigs.

So, if you switch to 32-bit mode to regain use of your plugins, you also loose 1 GB of RAM as well.

Needless to say, this has a serious effect on the performance of Photoshop with almost all plugins. As noted, I can no longer do a Save for Web and Devices, because (again, on my 8 GB machine) I “don’t have enough RAM.”

As a fine-art photographer whose gallery-displayed works depend on plugins, the upgrade to CS5 has been a disaster for me… or at the very least, a waste of $$$, and will remain so until such time as the plugins I’ve come to know, love, and depend upon, are made compatible with 64-bit mode, which recognizes all 8-gigs of my RAM.

Meanwhile, you may be able to get around it by visiting prefs and jamming the performance slider all the way to the right, so that you’re using “all” 2.1GB. (Success depends on your individual plugins, setup, etc.)

Sorry to be the bearer of bad tidings, but until the rest of the plugin world catches up, CS4 may be the only way to fly.
