Persona Q2 Dropping frames

Been playing PQ2 for a day now, however it drops frames consistently, the game runs at 30FPS and it drops into the 23FPS area. I know it can hold 30fps, but how do I keep it consistent?

I am running an Intel i5-2500
with a AMD Radeon R9 290x

I would take a guess that it’s your Radeon card holding you back, AMD’s OpenGL drivers are bad on Windows. I got some laptop with i7-4710MQ and GeForce 840M and it was ~3x faster than a i5-6500 with R9 390.
