Re: Photoshop still using scratchdisk with 16GB of Ram

I\'m going to have to respectfully disagree.. I\'ve got photoshop using just over 10GB of ram right now with a simple image upres, again with quite a bit of read/write scratchdisk activity (Used up 282GB of temp space on the C: drive according to explorer).. However the memory was still incrementally being used up as the progress bar was completing.
hmm... my guess is that not all of them are \"physical\" memory, the process monitor might have included the \"virtual\" memory being used as well. But you should be able to check how much physical memory it has used, don\'t have a windows in front of me so I can\'t verify though. Again, according adobe, CS3 uses about 6GB.
From Adobe TechNote When you run Photoshop CS3 on a computer with a 64-bit processor (such as a, Intel Xeon processor with EM64T, AMD Athlon 64, or Opteron processor) running a 64-bit version of the operating system (Windows XP Professional x64 Edition or Windows Vista 64-bit) and with 4 GB or more of RAM, Photoshop will use 3 GB for it\'s image data. You can see the actual amount of RAM Photoshop can use in the Let Photoshop Use number when you set the Let Photoshop Use slider in the Performance preference to 100%. The RAM above the 100% used by Photoshop, which is from approximately 3 GB to 3.7 GB, can be used directly by Photoshop plug-ins (some plug-ins need large chunks of contiguous RAM), filters, or actions. If you have more than 4 GB (to 6 GB), then the RAM above 4 GB is used by the operating system as a cache for the Photoshop scratch disk data. Data that previously was written directly to the hard disk by Photoshop is now cached in this high RAM before being written to the hard disk by the operating system. If you are working with files large enough to take advantage of these extra 2 GB of RAM, the RAM cache can speed performance of Photoshop. Additionally, in Windows Vista 64-bit, processing very large images is much faster if your computer has large amounts of RAM (6-8 GB).
