Call of Duty 5: World at War
Call of Duty 5: World at War is one more game that does not record the bottom frame rate. The CrossFireX tandems are all right in terms of average speed, though. The GeForce GTX 260 enjoys a big advantage over the Radeon HD 5770 here. The Radeon HD 4770, on the contrary, is closer to the HD 5770 than in the previous tests.
Warhammer 40 000: Dawn of War II
Warhammer 40 000: Dawn of War II is one of the most CPU-dependent games in this test session. Suddenly, we see the Radeon HD 5770 and HD 5750 deliver higher performance in CrossFireX mode. I say suddenly because the Radeon HD 5870 and HD 5850 had performance drop in this mode in our earlier tests. This problem must have been solved in Catalyst 9.11 and CrossFireX technology works in this game now.
There are no definite leaders here. The CrossFireX configurations are as fast as the Radeon HD 5870 and HD 5850 in terms of average frame rate, except at 1920x1200 with the high-quality settings. The opponents are not always equal in terms of bottom speed, though.
The GeForce GTX 260 is ahead of the Radeon HD 5770 at 1920x1200 and is equal or slower than the later at 1280x1024. Thus, the Radeon HD 5770 betrays a lack of memory bandwidth again.
The CrossFireX tandems beat the single Radeon HD 5870 and HD 5850 cards in the low-quality mode and equal them in the FSAA+AF mode. The game does not allow measuring its bottom frame rate but it seems to run smoothly on either CrossFireX configuration. No lags or jerks in the integrated benchmark as well as in the game proper.
