Crash Team Racing for example uses both, where a stage is split up into "rooms" (BSPs), and visibility regions (PVS) exist within those rooms so the PS1 has even less to render, further improving performance

Many parts of the code are really interesting. The full game was probably under 100k lines of code, and shockingly neat, considering the time budget they had (which was around 8 months). The game uses a combination of BSP and PVS (similar to Quake) to render so many polygons. They baked PVS into limiting the number of BSP leaf nodes to test for visibility, and also limits the number of polygons to draw within each leaf (bit indexing 0-32). The PC port will keep PVS for BSP, but we'll just draw all triangles in the leaf, cause the vertex shader will run faster if we just draw 32, rather than trying to pick individual triangles. This optimization will come when we're ready to scrap Prim/OT in favor of VBO/IBO.
