As far as I can tell, Photoshop 3 in 1994 had a PowerPC version? If 68k emulation was a bottleneck, wouldn't they be testing Connectix Speed Doubler's improved

  Yes, I think you are right - but the explanation (this is a long time ago, so hazy memories) was the following scenario: you had invested in some Photoshop plugins, or there were some stock filters/plugins inside Photoshop which were not yet optimised for PPC. You wanted them to go fast, so you stayed on m68k for a while until the vendors sorted it out. Also myth and lore was much more an everyday part of life then. It was hard to come by accurate information. I was really geeky, yet I never heard of the Speed Doubler until today. It indeed seems to be a very clever product, essentially JIT compiling 68k code?!

    Correct - the main application would move to a new CPU/OS much MUCH faster than some or all of the filters/plugins, and many more were not part of Photoshop at the time. You'd have things that are now considered standard tools that would be implemented by a plugin; I recall companies in the early 2000s that still had older Macs around for a particular plugin for a particular customer, as it never migrated. Even now you have that problem; I have a photoshop plugin for x86 that hasn't moved to a M1 native yet.

    The built-in MacOS 68k emulator also used dynamic recompilation starting with the PCI PowerMacs (introduced starting in 1995)
