30 FPS is quite playable. I will always look for a 60 FPS patch, but if there isn't one, it's not gonna stop me from playing a game I like.
I had to play PC games at 30-40 FPS for the longest time because I didn't have a powerful gaming PC. As long as the framerate doesn't drop below 30, it's not that bad.
The bigger problem is games with frequent framerate drops or games that run at 20 FPS (or less), like so many N64 games did. They are kind of tough to enjoy, the framerate becomes a constant distraction/annoyance at that point.
Zelda OoT/MM are so much more enjoyable with a 30 FPS patch. Despite causing a lot of cutscene softlocks, I still rather play them in 30 FPS and toggle it off whenever I encounter a crash.
