I think it really depends on which version of photoshop you are trying to run. Older versions should run better afaik. I’m not sure the current version even runs with all the cloud dependencies. You probably just need to try it out and compare directly. I moved my photo editing to photopea so I can’t really tell you more.

Nice. Thanks for the Release. Can’t wait to play around with the new notifications
