It depends on what you did. Photoshop wasn’t fully recompiled at first but they did get key performance tasks written to a PPC plug-in running inside 68k emulated Photoshop.

And it screamed. Faster than anything before it.

The fact that emulated 68k code could call native PPC was nuts to me but it was how most of the classic OS worked on PPC, with native parts being slowly rewritten over time.
