I have just used this program to limit my FPS and it has helped loads with my stuttering. Say you get an average of say 40 to 50 FPS, then just set the limiter to 38 FPS in Bandicam just couple FPS lower then the lowest FPS. Untick the only when capturing under Bandicam FPS tab so that you can just use it as a FPS limiter. Anyways, it's worked for me and made the game much smoother. Maybe they should add a FPS limiter to the game itself.
