AMD Radeon 6900 & 6800 Updated - F1 2010

Article Type: 

F1 (Formula 1) is a new racing title from Codemasters. Like their previous title (DiRT 2), F1 makes extensive usage of DX11 technology with cloth, fluid dynamics and tessellation. The title is much more strenuous on both single screen and Eyefinity, compared to DiRT 2.

At max settings the title hits a CPU cap (with a stock Core i7-920) of ~70fps on a single widescreen, with any pair of 6800 or 6900 series cards in CFX. Single 6900 series cards max out at just under 70fps.

A 2GB card is required for Eyefinity at 3x1920x1080p. 2GB cards in CFX max out at ~45fps, at both 3x1600x900 and 3x1920x1080. 1GB cards are playable at 3x1600x900, with the 6870 crossing 30fps.

I really don't understand why, but in a single widescreen 1920x1080 consistently outperformed 1600x900 by 1-2fps (at the CPU limit). I can't explain it, but I can repeat it. Maybe F1 just doesn't like an "odd" resolutions such as 1600x900. Maybe it is tuned for 1080p, and is having to do some sort of interpolation for 1600x900.
