While chunks are being updated anywhere, the game says my fps is around 60 when the look movement and player movement are extremely choppy stuttering. When VSync is turned on it decreases the fps to 30 and the stuttering is still there. My settings are; Graphics-Fancy, Render Distance-Far, Smooth Lighting-Maximum, Performance-Max FPS, 3D-off, View Bobbing-on, GUI Scale-Normal, Advanced OpenGL-OFF, Brightness-Moody,Clouds-ON, Particles-ALL, Server Textures-ON, Fullscreen-OFF, Use VSync-both. Maximized Window on 1920 x 1080 monitor. Generated new world for testing. As the chunk loading subsides you can stand still and look around smoothly.
The FPS is high again in 1.5.1.
