Same. It was borderline unusable on Tahoe to the point I had to downgrade it, but the Golden Gate beta brought it back to life.
I’m only using it as a travel machine now, trying to hold on from upgrading it until I can get an Air with OLED display - hopefully coming in <24 months…
They clearly did a bunch of optimizations, because working on my Xcode projects (and even basic every day use tbh) in 18.x was fine, on 27.x it’s mostly fine, but on 26.x it was a slog fest.
