The VTX is a cost-reduced RealityEngine and as a consequence, its features and performance are below that of the RealityEngine. It is not the VGX or [[VGX (award show)|VGXT]] board set. The name is said to stand for Venice To eXpensive, Venice being the internal name for RealityEngine. |

The RealityEngine2, stylized as "RealityEngine2", is an upgraded RealityEngine with twelve instead of eight Geometry Engines. The Reality Station workstation is based on RealityEngine2.[1] In February 1995, SGI reduced the entry price of Reality Station to US$179,540 (equivalent to about $359,000 in 2023).[2]
RealityEngine2 was succeeded by the InfiniteReality in early 1996. It uses the GE10 Geometry Engine board, RM4 Raster Manager board and DG2 Display Generator board.
