when i came on board the app was drawing quads, I changed it to triangle strips and then to a single triangle strip with degenerate triangles linking them. on the non graphics side I've changed a bunch of the logic around to use less objects and arrays and more things that I know the cpu can do in a few cycles. I am trying to do some serious multithreading on the logic part but so far that doesnt work yet. I have something wrong with my synchronization. I was also looking at aparapi and opencl to move some of that to the gpu but it's such a daunting task to start that I've pushed it back until this season.

can you tell me more about the layered caching? what I would love to do is send just a delta of the vertices that have changed since the last erosion cycle that would cut down the amount of data sent to the gpu by 95% or so, but I dont know how to allocate that in the gpu.
