Not sure what you did.
But you guys hit the nail on the head. In the editor I can have up to 8 (and even more) actors at once with no frame drops, (Until their A.I. kicks in and they start trying to knock heads together. Then it's rip FPS.) Otherwise, the FPS is extremely better in Arena mode. It's actually playable now. With 2 actors (Including the player), it plays perfectly, occasionally there's like 1-2 fps that gets dropped, all the way up to 4 actors, (Including the player), where the most it'll drop is 5-6 fps. But then if it's 5 or 6 actors it starts drastically dropping again. Although, if it's on Stucco Courtyard, the FPS problem is still there. Also, blood is a gargantuan FPS killer now. But it's the Internal Testing branch, so if the optimization was on purpose, you guys did a great job, because the game is playable again and i'm able to continue development on my project. What exactly did you guys do? (If you guys even know what you did.)
