Thank you for the replies and your time.
The more I read, searching on Google, about large .tiffs and Win7, I see there is a widely known bug/problem in Win7, and MicroSloth knows about it also.
The "file exploder" will consume 100% memory, yes, I have the preview pane OFF, and the search indexer OFF.
As I've said, this is a known problem in Win7, that did not occur under Vista, nor XP.
I now use Q-Dir to navigate about.
Seems to work good.
Bridge works good too, just have to increase the cache size.
Anywho, my system is a Dell XPS17 laptop, Intel Core i7-2670QM - 4 cores, 8GB RAM.
My GPU is a 3GB nVIDIA GeForce GT 555M.
My current settings in Win7-64 is for an custom managed initial paging file of 8386MB, and a max of 24258MB.
The ONLY Visual Effects selected is smoothing edges of screen fonts, all the other eye candy waste is turned OFF.
My CS5 settings are, let PS use 5334MB, 75% of RAM. Hmm, might increase that?
PS scratch disk is C:, hmm, maybe an SSD would help?
My current stitching experiment is a 42 image stitch from a 5DmkII using a Mamiya 645 120mm f4 Macro, 19907x12543 pixels, 249.69MP, 2.063GB .tiff file generated from MS ICE, an app which I really like.
Opening this file in PS-CS5 results in constant HDD usage, it does open, and I can even eventually get Topaz Denoise 5 to process the file, though, this is far too time consuming.
And then, I'm worring about my drive usage/lifespan.
As I have been pondering the purchase of a digital medium format system, I am not interested in 8bit files, thanks.
I can only wonder in amazement what system is needed to do this type of work.
Guess I need a 16GB+ mega desktop to do what I want?
