Try around 36%. And that is just the lag.

It isn't just a handful of users.
If you're going by PS3 users, then yes, the percentages are far too high, but if you're going by total skyrim players (spread over all platforms), I bet the percentage of people experiencing game breaking issues is not that high.
Still, if 36% of your PS3 players is experiencing severe frame-rate drop, it's something that one would have expected to be found during testing. I can well imagine that Skyrim's PS3 audience is angry, and they have every right to be.
Bethesda should probably try to focus all their attention on the PS3 version, us PC gamers probably don't mind waiting (and if all else fails, we have the modding community to turn to). The 360 version of the game (from what I've heard) isn't experiencing (too many) game breaking bugs.
