Model 2
Arcade 3D revolution
Sega's Model 2 arcade board delivered unprecedented texture-mapped 3D graphics, powering Daytona USA, Virtua Fighter 2, and other titles that defined mid-90s arcades.
Overview
The arcade 3D leap. Model 2 succeeded Sega’s flat-shaded Model 1 with texture-mapped 3D graphics — bitmap images wrapped onto polygons rather than just flat-coloured surfaces. The visual improvement was dramatic: Daytona USA (1994) cars gleamed with reflections, Virtua Fighter 2 (1994) characters gained skin, clothing, hair detail. For several years no home console could match what Model 2 delivered in arcades. Sega’s arcade dominance from 1993-1997 was largely Model 2’s doing.
The board was a partnership: Sega designed the system, Lockheed Martin’s Real3D division (formerly part of GE Aerospace) provided the GPU silicon — military flight-simulator graphics technology repurposed for arcades.

Key titles
| Game | Year | Genre | Notes |
|---|---|---|---|

| Daytona USA | 1994 | Racing | Iconic; “Let’s go away” theme; sold thousands of cabinets globally |
| Virtua Cop | 1994 | Light-gun shooter | Template for House of the Dead |
| Virtua Striker | 1994 | Football | First major 3D football game |
| Sega Rally Championship | 1995 | Racing | Off-road / surface-feel breakthrough |
| House of the Dead | 1996 | Light-gun shooter | Horror-themed Virtua Cop successor |

Visual advancement
| Feature | Model 1 (1993) | Model 2 (1993-94+) |
|---|---|---|
| Surfaces | Flat-shaded polygons | Texture-mapped polygons |
| Detail | Geometric / abstract | Detailed real-world appearance |
| Lighting | Per-polygon flat | Per-vertex Gouraud shading |
| Realism | Abstract — early Virtua aesthetic | Approaching photorealism for the era |
| Impact | Impressive arcade novelty | Genuinely revolutionary |
The Virtua Fighter 1 (Model 1) → Virtua Fighter 2 (Model 2) jump was the most visible single-generation upgrade in fighting-game history at that point — same characters, same gameplay, dramatically more detail.
Console gap
Through 1994-1996 Model 2’s arcade games were noticeably ahead of home console hardware:
| Platform | Year | Comparison |
|---|---|---|
| Sega Saturn | 1994 | Struggled to match — Virtua Fighter Saturn port reduced detail; Daytona port famously rough |
| Sony PlayStation | 1994 | Strong 3D, but different approach (more affine, less hardware texture filtering) |
| Nintendo 64 | 1996 | Closer match — texture filtering, perspective correction; but smaller textures |
| Arcade advantage | — | Model 2 was years ahead of typical home 3D until ~1996 |
| Model 3 | 1996 | Widened the gap further before consoles caught up |
The Saturn port of Daytona USA in particular illustrated the gap — the same game running on a home console looked visibly inferior to the arcade. Sega ports got better (Virtua Fighter 2 Saturn was much improved) but the arcade-vs-home parity didn’t truly arrive until Sega Dreamcast (1998).
Lockheed Martin connection
Model 2’s GPU was developed by Real3D — initially the General Electric Aerospace simulation graphics division, spun out as Martin Marietta in 1992, then merged into Lockheed Martin in 1995. The technology had originally been built for military flight simulators where photo-realistic terrain at 30+ fps was the requirement. Sega licensed it for arcade use.
This explains Model 2’s particular strength: it was military-simulation-derived graphics technology, with strong texture filtering, atmospheric haze, and large draw distances — features that made Daytona USA’s long straights and Sega Rally’s rolling hills feel real.
Real3D became part of Intel in 1999; the technology lineage continued in Intel’s 740 graphics card (1998), which used Real3D-derived design.
Successor: Model 3
Model 3 (1996) succeeded Model 2 and pushed further:
- Performance: ~1 million textured polygons/sec
- Notable games: Virtua Fighter 3, Sega Rally 2, Daytona USA 2, Sega Bass Fishing, House of the Dead 2
- Texture filtering / lighting improvements
By Model 3’s late life (1999-2000), Dreamcast at home was matching arcade quality. The Sega arcade-vs-home advantage gradually evaporated; Model 3 was the last generation where Sega arcade hardware was clearly ahead.
Legacy
- Sega’s mid-90s arcade dominance was largely Model 2’s doing
- Influenced PC graphics through Real3D → Intel 740 lineage
- Sega’s arcade-perfect ports strategy (Dreamcast 1999+) was the response to Model 2’s home-console gap
- Modern emulation — Supermodel emulator runs most Model 2/3 games; the arcade catalogue is preservable
