NCAA Football 14 [BLUS31159]

Hello. I'm new to the emulation and RPCS3 scene, and I have a few questions. Firstly, I seem to have gotten the game to run smoothly, except for when the ball is in play. I still manage to get roughly 35 FPS, but the speed of the game itself slows down significantly. I read in other parts of the forums that this could be due to my CPU not meeting the demands of the physics threads. This leads me to my second question. Like others have mentioned in this thread, the in-game audio crackles a ton. The music in the loading screens work, and the famous "EA Sports, it's in the game" sound clip sounds fine, but as soon as the football game starts, the sound starts to crackle. Is this also due to my CPU not being able to handle the physics/audio threads as well? I understand that I won't be able to run the game at 4K with these specs, but I figured I'd be able to at least run the game at 720p respectably.

Thank you.
