I'm not wanting to blame the engine, but what I see is the frame rate on a 800 MHz dropping badly when looking at the length of the Ark. Nardulus seen this also, and suggested I place a partition wall or walls blocking the length view of the Ark. That idea would have worked.

Looking at the side hull the frame rate booms upwards, but looking down the length of the Ark, then the frame rate drops to 20 or less.

Are the curved levels you make are they the size length-wise of this Ark??? I'm very interested and curious if so. Take a walk length wise in the Ark and see if your curved surface levels are of this size?

Hey, you changed your avitar again! What happened to that old classic pirate guy avitar you used to have? lol
