I have used for years Phtoshop C6 as a full license, recently I’ve decided to buy the subscription model as the monthly rates are quite reasonable for Photoshop + Lightroom. No regrets I wish I had done it before as the Adobe team are real wizards. There is however a problem, the memory used by Photoshop (not Lightroom) when working on an image (not intensive operations) more often than not spikes to 7GB (I have 8GB maximum) visibly slowing down the performance, even though in preferences I have assigned the minimum to Photoshop (55%). I never had this problem with PS C6… I wonder whether I’m doing something wrong or should I upgrade my memory to 12 GB (max on this computer).
Submit a bug report or issue or contact support? If you're a paid customer, they should respond to u. This forum is not the best place to ask why your photoshop is missbehaving. I would go directly to their paid support. You're paying after all. Otherwise, try one of these tools (some are older, if it doesn't work or causes slowdowns, try another): https://www.donationcoder.com/software/mouser/popular-apps/process-tamer https://bitsum.com/ https://github.com/lowleveldesign/process-governor https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer https://www.blogsolute.com/monitor-application-memory-usage-and-limit-them/6485/ https://battle-encoder-shirase.en.uptodown.com/windows https://docs.microsoft.com/en-us/windows-hardware/drivers/devtest/application-verifier , run photoshop in resource-constrained environment https://download.cnet.com/Minimem-64-bit/3000-2094_4-75337961.html (worth a try I guess) Yes some of these are for cpu. But they work for memory too. Some of em I suppose.
This probably depends on a lot of factors. I opened an image to check and I can't get it to use more than 1 GB of RAM. Not sure what kind of image you are working with or what you are doing to it. As suggested reaching out to their support might be the way to go, especially if it is repeatable.
Ye seems to be abnormal behaviour. That said, he's probably a professional while you're just drawing circle and squares, not really comparable xD
