Classic game, classic hardware: [H]ardForum member TheeRaccoon is one of the lucky few to get his hands on a Quantum3D Mercury “brick,” which comprises four Quantum3D Obsidian2 200SBi video boards. As The Dodge Garage explains, these were generally used for multi-channel visual simulation and training applications back in the day, but as TheeRaccoon’s video proves, they can also run a certain Valve shooter just fine. Thanks for the share, erek. After a little over a year of ownership, I finally present to you the legendary Quantum3D Mercury brick up and running! (Don't mind my ghetto homemade passthrough cable.) In this brick configuration, there are 8 Voodoo 2 chipsets in SLI! (Each 200SBi board has two Voodoo 2 chipsets in SLI mode.) These bricks were mostly used for military simulation in the late 90's/early 2000's. The image generated by each 200SBi board is combined into one image, giving you 4 tap rotated grid full scene anti-aliasing.
