These devices do not have enough polygon throughput and/or CPU power to use run-time displacement mapping to any useful extent. However, you can tessellate and displace the data using software either at installation time or at start of day. By tessellating according to the CPU speed of the machine and tessellating multi-ple versions of each mesh, you still gain the advantages of adapting polygon count to the scene complexity, machine capability, and the size of each mesh on the screen without having to author them directly.
