The Creator3D hardware doesn't do texture mapping, so anything that requests textures will fall back to a software renderer. That's probably what you're seeing.

It really does have 15MiB: The 3DRAMs are essentially 16Mib DRAMS with 6Mib worth of area turned into pixel-writing logic. So 10Mib of RAM * 12 chips is 15MiB total. It's organized into 5MiB each for buffer A, buffer B, and Z. Jon Leonard
