The G400 chip supports, in hardware, a texture-based surface detailing method called Environment Mapped Bump Mapping (EMBM). EMBM was actually created by BitBoys Oy and licensed to Matrox. EMBM was not supported by several competitors such as NVIDIA's GeForce 256 through GeForce 2, which only supported the simpler Dot-3 BM, but was available on the ATI Radeon 7200. Due to this lack of industry-wide support, and its toll on the limited graphics hardware of the time, EMBM only saw limited use during G400's time. Only a few games supported the feature, such as Dungeon Keeper 2 and . EMBM requires either specialized hardware within the chip for its calculations or a more flexible and programmable graphics pipeline, such as later DirectX 8.0 accelerators like the GeForce 3 and Radeon 8500.
