hmmm -this sounds just like the bug I get with Leaf RAW files.
for some weird reason, I get this same error with max RAM @ 100% (1777MB), and at 90%, but it seems to work fine now at 89%. now yours doesn’t work @ 85%?
obviously, we have enough RAM, sounds like a bug to me. I just posted mine to the CS bug topic. looks like CS doesn’t "like" certain percentages for max ram.
Craig and Ellen,
With PS7 and earlier versions, a 75% RAM allocation is apparently the most Photoshop would use, regardless of a higher amount being selected. This was said to be a limitation due to Windows rather than Photoshop itself. While the same should still be true for PS CS, I know there was a thread somewhere that users commented on seeing better performance with an even lower RAM allocation specified…40-50% I think. Scott Byer acknowledged that as a trade-off for some of the improvements made in PS CS. I don’t recall where that thread was.

This particular problem is happening because an application cna only address 2GB of address space on Windows. So, by setting Photoshop’s memory percentage high, nearly all of that address space gets pre-allocated for image tile purposes. Leaving nothing left for regular allocations. Yeah, there is a scheme in place to try and leave enough for normal operations, not matter how high the slider gets set, but the program grew a little more than expected.

If I understand correctly from here and another thread I just read, you’re saying that the plugins (especially the RAW plugin) can take additional memory above (or outside, if that’s a better term) what’s allocated to photoshop in the settings. Is that correct scott?
thanks, dave
Yup. They sometimes need to allocate "regular" memory (as oppose to image memory) but it all comes out of the same address space bucket.

but it all comes out of the same address space bucket.
Ah. The key sentence. That explains a lot. Thanks Scott!
