So,this dumbass has a question,so step up if you know the answah!! Working with a macpro (4x3.0ghz) with 2 GB memory. With photoshop CS2 the normal memory allocation showed that normally (5 pics,each of 72MB) the memory load was at 1.4GB of 2GB in use. Like,always. Memory allocation was 80%. Now,with the CS3, the memory use is around 600MB when workin with similar pics. The mem.allocation is 80%. So,is the CS 3 so much more effective in memory use than CS 2. Would there be increase in performance if i would get more memory,say 2-4GB,as now it seems that I dont even use all the mem that I have?!! *****..this is complicated..
