Update: I found out it DOES affect some groups of four whitish crystalline looking enemies (like the Vehement Idols in the Monad block of Tartarus in P3 FES), but again, the problem is the same as before:Īs long as the camera is looking at scene from a certain angle, the FPS drops. Fighting four of these types of enemies does not seem to cause a problem. I've noticed this affect groups of three. I have no idea if this a bug, a flaw in the emulation, or if my hardware sucks, but since I've been able to play both Persona 3 FES and 4 near flawlessly save for a few areas that drop into the 50 FPS area (certain Full Moon bosses like the Strength/Fortune Boss in P3 FES, and the Naoto boss fight and dungeon entrance in Persona 4), I'm disinclined to believe my hardware sucks, but if anyone can prove me wrong or inform me just what the deal is, I'm willing to listen. In Hardware it stays around 50 FPS, and it plays mostly okay aside from the slowdown until you kill one of the enemies, then it goes back to 60 FPS. Note: I tested it in both Direct X 11 Software and Hardware, and as long as you don't move, the FPS is okay in Software, but drops whenever anyone attacks. SPU-X (Async On, which seems to negate music slowdown whenever this FPS problem occurs with no negative consequences when FPS is normal) It seems to be a rendering issue graphics wise, from what I can tell, since I have no speedhacks on, and below are my current settings

In fact, ANY enemy of this color arrangement in groups of three starts causing FPS lag. In both Persona 3 and 4, I have noticed that fighting certain groups of enemies causes the FPS to drop 10-15 pointsĪll the enemies in question are usually whitish or crystalline in appearance (like the Emperor Beetles in the final block of Tartarus in P3 FES and their counterparts in the final dungeon in Persona 4), and the FPS only starts crapping out when you fighting three of these types of colored enemies.
