I can't play this game because of the choppiness, I've tried messing with the config file and I've set the core to dynamic, the cycles to manual 30000 (and up to 175000, didn't work) I've tried different outputs, compability modes

When I set the core to dynamic it actually works fine, for 5 minutes, then choppy for 5 minutes, then back to fine for another 5 minutes and so forth

I'm running out of ideas and I really want to play this game.
Please help!

Just to make sure: You are not talking about the unique style of the cutscenes as seen in this video?

I have my game set to 25000 cycles on a dynamic core with Direct3D and I don't experience any problems.

Nah, It was even during transition of the screens when in gameplay.

I actually bought a new laptop and even though I haven't tested Last express on it yet I'm pretty sure this won't be a problem anymore ;)
