Performance in RPG
Alas, there are problems with CrossFire in this game, too. There is no or little performance gain relative to the single card, which indicates the use of only one graphics core. Moreover, the minimum speed plummets at high resolutions.
The current version of the game doesn’t support FSAA, so we performed the test with anisotropic filtering only.
The dual-chip Radeon HD 3870 X2 is again slower than the single-chip Radeon HD 3870 in terms of average frame rate, even though slightly. The minimum speed is considerably lower, however, which is indicative of certain flaws in the current version of the Catalyst driver.
