Immediately upon loading or starting a world, the frame rate will freeze or dip to ~4 fps. The ram usage will shoot up to ~ 2GB and then be immediately cleared to ~200 MB in a period ranging 2-7 seconds and will repeat this cycle indefinitely. Freezing occurs while ram usage is climbing, and occasionally when ram is cleared. This occurs regardless of whether the field of view is changed or not. Also occurs while the game is paused.
