Rainbow Six : Vegas
The first PC game based on the Unreal Engine 3.0, Rainbow Six : Vegas is still a very resource heavy game. We measure performances in the introductory scene. The HDR mode is activated as it is more or less obligatory as without it banding is very noticeable. Shadows are set to “low” because a higher quality in this domain lowers performance too much in certain areas.
Originally designed for the Xbox 360, this game seems to have a natural affinity for the Radeon HD which has a similar architecture to the game console’s graphic chip. In addition, CrossFire allows almost doubling gains as the Unreal Engine 3.0 is particularly at ease with a multi-GPU system. The Radeon HD 3870 X2 gives it everything it has resulting in twice the performances of the GeForce 8800 Ultra and does almost 20% better than the GeForce 9800 GX2.
The game does not support antialiasing but Nvidia has implemented it to drivers as it has done with Oblivion. This is contrary to AMD who unfortunately didn’t make this effort.
