Red Faction 2 Issue in Single Player Mode

[Weatherdynamics]

I am experiencing a weird issue with Red Faction 2. There are certain places in single player mode where the speed slows to 30-60 FPS. Usually happens at cutscenes, including the opening one. I don't think it is strictly a hardware issue because when I pause and then resume the emulation during a slow part, it then runs at full speed. It seems that slowdowns usually occur when GS gets close to 50%. When I do the pause and resume trick, GS is generally at or below 40%. Multiplayer works fine with GS mostly below 25%.

My hardware is: AMD Phenom II X4 965 @ 3.4 HGz, 8 GB DDR3, GeForce GTX 650. I am running PCSX2 1.2.1 at native resolution. Using Direct3D 11 (hardware).
