G Police: Weapons of Justice is another PSX game that really pushed the hardware. The first one was pretty damn graphically intensive, but the 2nd one (WoJ) was just too much. The developers actually resorted to WIRE FRAMES for some of the buildings in the near distance so you could see them coming before your chopper slammed into them. As you got closer, the wire frames would fill out with textures (but you were on top of them at that point.)
