Performance in Strategies
We use DirectX 11 mode for graphics cards that support it.
Alas, the Radeon HD series has a very low bottom speed in this game even when we take the new Barts-based solutions. Although the average performance of the Radeon HD 6870 and 6850 is high enough, their bottom speed is downright poor. Meanwhile, the GeForce GTX 460 768MB is quite capable of keeping the frame rate as high as 30 fps even at 1600x900.
StarCraft II: Wings of Liberty
The main achievement of the Radeon HD 6800 in this test is that the bottom speed is much higher compared to the Radeon HD 5850. The senior model of the new series even outperfroms the GeForce GTX 470 at 1920x1080. The resolution of 2560x1600 is, unfortunately, not playable due to the low bottom speed even though the Radeon HD 6870 is close to delivering the desired 25 fps.
