If you modify the third parameter of FFTOceanSurface which is called numTiles you will be able to increase the number of tiles that make up the ocean surface and thus the range. Increasing the number of tiles will have a direct effect on performance. You may wish to try the new vbo technique in the trunk to reduce update times.
