We don't use GPU in our ImMesh, which achieves real-time performance on just a CPU-only platform. For visualization, we use OpenGL for rendering.

Is GPU necessary or not? It depends on the scale of your maps. For non-large-scale mapping (e.g., total traveling length < 1 Km), the GPU is not necessary. On the contrary, rendering the map with a GPU indeed improves the rate of previewing.
