Performance in Real-Time Strategy
Red Alert 3
The game has a built-in frame rate limiter set at 30fps.
As we noted in our review dedicated to Red Alert 3, Nvidia’s solutions are significantly inferior to ATI’s in this game if you turn on FSAA. This is true for the current version of Nvidia’s driver, at least. And while this situation lasts, we can only recommend you to disable FSAA if you want to play the game on an Nvidia graphics card. The performance of the Sapphire HD 4850 X2 is affected by slow GDDR3 memory at 1920x1200 where its bottom speed sinks below playable.
The game has an integrated frame rate limiter set at 30fps. It doesn’t support FSAA.
This test does not give us useful information. All the cards hit the frame rate limit and do not differ much in terms of bottom speed. Perhaps we will replace this test with a more informative one in our future reviews.
World in Conflict
The two opponents are roughly equal at resolutions up to 1680x1050, but the Sapphire HD 4850 X2 goes ahead at 1920x1200. Besides the 24% lead in average speed, the Sapphire can maintain a bottom speed of 25fps and higher. The Leadtek WinFast GTX 280 can’t match this performance. When it comes to the resolution of 2560x1600, neither card is capable of providing an acceptable bottom speed although their average frame rates are good enough.
