Six Monitors (6048x2276): One/Two Cards
Six 1920x1080 displays yield 5760x2160. So why the weird resolution? When you tweak the bezel compensation feature, you actually increase the overall resolution. And if you want to actually realize the benefits of bezel compensation, you need to specify the higher-resolution setting in your game. Selecting 5760x2160 effectively disables bezel compensation.
In the chart above, blue bars represent performance at 6048x2276 with a single Radeon HD 5870 Eyefinity 6 Edition card. Left 4 Dead 2 is certainly playable, and DiRT 2 can easily get away with 30+ frames per second. But, for the most part, those averages are on the low side.
Adding a second card (the red bars) definitely gets us closer to where we want to be, pushing DiRT 2, Call of Duty, Left 4 Dead, Far Cry 2, and to a greater extent Battlefield: Bad Company 2 and S.T.A.L.K.E.R. into the realm of playable.
One of the things Nvidia’s representatives are particularly proud of is the GeForce GTX 480’s scaling in SLI. Indeed, near-doubling of performance in some cases suggest that Nvidia is really getting the most out of its multi-card rendering technology.
If we were going to see exceptional scaling anywhere, it’d be at an extremely high-resolution setting like this one. CrossFire doesn’t seem to scale quite as aggressively as SLI; however, DiRT 2, Bad Company 2, S.T.A.L.K.E.R., and Far Cry 2 all see formidable boosts.
