You must be using extreme values of tile size to get a tile that is 8MB in size. 50k to 200k would the normal range. Please just use defaults, the result will be a much better balanced scene graph. FYI, 3GB is rather small for what VPB and database paging can handle. VPB allows you to build multi-terrabyte databases and the database paging allows you to rendering them at a solid 60Hz. All you need to do is trust in the defaults.
