Damn! I had a long comment which nether was saved or published. It said I have no edit permission.
My limit is more like $800.
Here goes again. A shortend version.
I had a conversation with a software person from a large, local software provider who claimed that the 2g limit is not an Adobe limit, but an MS limit. He claims that MS divides the 4G process capability 50/50 between itself and developers. In a recent thread about running without scratch, the concept of a 3G "switch" was mentioned by dave milbut. Apparently, his company makes use of this for their clients who have major problems with the 2G limit. He also was suprised that i can and have run beyond 2G when editing in 16 bit.
My question is: Can PS also make use of thie redivision of process limits, and is this process limit also responsible for the problems some people see when trying to use 2g ram?
Lawrence, you said that you "have run beyond 2G" do you have more than 2Gigs of ram installed, or do you mean that you had a scratch file bigger then 2Gigs?
There is no way I have ever heard to make PS use more than 2Gigs of Ram, on PC or on a mac… the scratch file can be humoungous , as it can support 4 hard drives…
No, not 2G ram, but 2+G scratch.
yes 2gig + scratch is very possible (probable in some cases! <g>)
The os is generally limted to 2 gig. Some cases (described in the other thread) 3 gig. BUT AFAICR all the adobe guys said that PS can not make use of more than 2 gig of ram regardless (because of the API calls used) and up until CS could not save a file greater than 2 gig in any format. Now PSB and TIF support > 2 gig file sizes, but the app itself is still limited to 2 gig ram (not including scratch).
So is there a differentiation between ram and process so far as limits? What does upping process to 3G buy? Also, Pierre spoke about tiles. Does scratch sccomodate multiple tiles whose size is based on available ram?
Inquiring minds want to know. 😉
What does upping process to 3G buy?
mostly high end server apps can use it… large databases etc.
scratch space is only limited by disk size (or if there’s an upper limit it’s so large that it’s never been discussed here, that I know of).
I wouldn’t worry about "tiles" as the adobe guys describe them. for all practial purposes they’re "black boxes"… data structures that you can’t change or affect (again, as i understand it). They’re twice the size in CS as they were in 7, hence the generally larger scratch sizes. What that buys you, i’m not sure, but I’m sure there’s a good reason for them. (performance? image quality?)
AutoDesk’s "Inventor" is the program that I have been referring to. Apparently, it detects if you have bumped up to 3G in boot.ini and can accomodate that move. Is there any capability/value to doing the same in PS? Will it relieve the problem some are having using a full 2G memory?
Is there any capability/value to doing the same in PS?
No, as far as I can recall from what Chris, Scott, Mark et. al. have said.
I always thought non-server OS’s built on the NT kernel were able to run able to accommodate 4gb of ram? Granted that still doesn’t change the 2gb limit of apps.
I think it’s greater than that for xp pro and 2k server matt. not sure what the limits are. 16? 32? more? xp home may be limited. a quick check of MS should clear it up, if it’s necessary.
