Has anyone tried Photoshop CS4 under Vista 64 and have any comments on performance, reliability or can report on any problems.
I’ve been using it for about a month w/ no probs.
I would also be interested on how much RAM has been used and what main processor and graphics card has been used.
My experimentation with large images involved a 129 megapixel PhotoMerge. I found it rather hard, even with aggressive memory management settings, to coax Photoshop into using more than 2 or 4 gigs of RAM. It also seldom uses more than one core, so CPU maxes out at about 25%, occasionally approaching 50%.
One interesting finding that I haven’t confirmed yet, is that the PhotoMerge, which was of a large building, was asymetrically distorted in 32 bit, and correct in 64 bit.
Main processor is an AMD 2.5 4 core, and Asus M3n78 Pro Mobo. Using the built in Nvidia 8300 graphics.
Is there one CD for 32 and 64 bit Photoshop
CS4 or are they different products?
One CD for both.
Other thoughts. 64 bit is the mouse that roared, only it’s not roaring.
From a marketing standpoint, Adobe is soft pedaling 64 bit. There is almost no functional or performance difference, other than capacity, which can be important for those who deal with large images.
There is almost no discussion of 64 bit porting issues in the developer forums, and very few plugin manufacturers have made the necessary changes to run in 64 bit. Bridge is still 32 bit. 64 bit should be a big deal, with manufacturers of camera backs, folks who composite large images, and other people who deal routinely with large images, have been waiting for. Just guessing that this may be an indication of their Mac centric approach, and things will perk up when the Mac is 64 bit.
It can even be confusing as to which version you are running – even on a 64 bit system, 32 bit PS is installed as the default. The easiest way to tell which is running is to look for the *32 next to the process name in Task Manager.
