WizMark is a 3D performance benchmark created by 3Dfx Interfactive, Inc. that measures the perfomance of Microsoft's Direct3D and 3D hardware accelerators. The benchmark utlizes essential 3D rendering features which provide enhanced visual realism including Gouraud shading, perspective correct texture-mapping, Gouraud texture modulation, texture bilinear filtering, texture LOD mip mapping, alpha-blending, and Z-buffering.
