Here's a cleaner (better than YouTube) version of the pre-rendered CG
FPS demo used to hype the M2:
It's the 4th video down "Shooter Room".
What I REALLY, REALLY, REALLY wanna see though, is video footage of THIS dungeon-corridor FPS scene in motion
Obviously this was also prerendered CG, not something M2 could've done.
I saw it in motion on television in 1995. As I recall it was incredibly smooth, 60fps, totally anti-aliased. The lighting was awesome. textures amazing. wicked cool. It looked better than anything that Dreamcast or PS2 ever did years later, and at least on par with the most impressive stuff ever seen on Xbox or Gamecube (maybe more so).
The truth is, even SGI's most powerful hardware of the time, Onyx RealityEngine2, costing $100,000 ~ $200,000 or upto several million dollars in multi-rack configurations, was NOT capable of doing any of these pre-rendered CG "M2 PR" demos, in realtime.
They were done, pre-rendered on lower-end SGI workstations.
I seriously doubt even SGI's then-next-generation InfiniteReality graphics subsystem released in 1996 with about ten times the performance of RealityEngine2 (IR could do 10 million+ polys/sec with all features) could pull that stuff off in realtime, either.
Not until we get to SGI's more modern hardware of the last 5 years or so, like UltimateVision released in 2003 which uses 4 to 16 (or more) ATI R3x0 GPUs (each equivalent of a Radeon 9700/9800) in parallel, could those CGI demos be done in realtime at 60fps. We could now (since 2005/2006) have that stuff and beyond it done realtime, in-game on Xbox 360, PS3, PC, no problem but it took a decade (1995 to 2005/2006) to get there.
If 3DO & Panasonic released a new system every 3 years or so, as they were planning (3DO: 1993, M2: 1996/1997 MX 1999 ?) we would probably be playing on M5 now. 3DO Systems/CagEnt was a few years ahead of the PC 3D industry (Rendition, 3DFX, PowerVR, 3DLabs, Nvidia, ATI, etc) and also ahead of Sony and Nintendo with SGI. If that trend had continued, their current console could've been better that other current-systems. Or not, since Nvidia & ATI got much, much MUCH better with the influx of engineers from SGI/ArtX, Evans & Sutherland, Lockheed Martin/Real3D, 3DLabs etc, and Sony switched from in-house graphics to Nvidia.
