The main issue I come across with Demul is that it seems to stutter at certain points.

Happens in all games I have tried but take Crazy Taxi for example, it will run at 60fps but during a camera transition, when you enter a new area of the map or pick up a new customer you get a noticeable stutter. It happens often enough to impact gameplay.

Is this to do with my hardware setup or is it a part of the emulator? Can you eliminate this with a more powerful CPU/GPU?
