Performance in Strategies
Command & Conquer 3: Tiberium Wars
The game having a frame rate limiter, you should consider the min speeds of the cards in the first place. This parameter determines your playing comfort in Command & Conquer 3.
It is the GeForce 8600 GTS that is better in terms of minimum speed although the Radeon X1950 Pro delivers a higher average frame rate. We are talking about 1280x1024, of course, because the min speed of every card, except for the GeForce 8800 GTS 320MB, is not higher than 19fps.
Company of Heroes
We tested the game in the pure speed mode with enabled anisotropic filtering only, because it has problems when you turn on FSAA.
Speeds have grown higher in Company of Heroes as opposed to the older testbed, especially the speed of the GeForce 8600 series. Yet even enjoying a 50% advantage over the Radeon X1950 Pro at 1280x1024, these cards still cannot make the resolution of 1600x1200 playable. Overclocked to highest frequencies the MSI card has a min speed of only 19fps. The Radeon X1950 Pro offers comfortable gaming conditions in 1280x1024.
The GeForce 8600 GTS performs worse here, perhaps due to its driver or to the transparent texture multisampling. The Radeon X1950 Pro, on the other hand, is never slower than 30fps and allows playing at 1280x1024 with enabled 4x FSAA and adaptive antialiasing.
