The Namco System 22 is the successor to the Namco System 21 arcade system board co-designed with the assistance of graphics & simulation experts Evans & Sutherland. It first had a limited release in 1992 with the game SimDrive and then a full release in 1993 with Ridge Racer. While the System 21 hardware design had the main CPU provide a scene description to a bank of DSP chips which perform all necessary 3D calculations, much of the graphics in the System 22 is now handled by the Evans & Sutherland 'TR3' GPU chipset, which introduced features such as texture mapping, Gouraud shading, and transparency effects, and handles depth cueing. TR3 stands for: Texture Mapping, Real-Time, Real-Visual, Rendering System.
A variant of the system, called the Super System 22, was released in 1995. The hardware was largely similar to the System 22, but with a slightly higher polygon rate and more special effects possible.
Both Super System 22 and System 22 can render significantly better graphics, more polygons with sharper texture-mapping, running in higher resolution and at a higher framerate compared to the graphics capabilities of the original Sony PlayStation, the Sega Saturn and the Nintendo 64 video game systems, but much less than the Sega Dreamcast can produce. [citation needed]
According to Namco America, the twin seat Ridge Racer arcade unit sold to distribution for $11995.00 in 1993, equivalent to $25300 in 2024. In Europe, the Ridge Racer Full Scale deluxe unit cost £150000 for arcade operators upon release,[1] equivalent to £376844 or $459248 in 2024.
