Topic: Poor Optimization of The Nippon Ichi SRPG (PS2 Classics)?

I noticed that both Disgaea 2 and La Pucelle Tactics don't run as well as the other PS2 Classics that I have downloaded. Both games are from the same developer so I was wondering if the games simply weren't properly optimized for the PS3. They aren't broken, but anime cutscenes and times when there's alot of action on-screen the games seem to struggle in-terms of their frame-rate...
