Call of Juarez
We can see the same in Call of Juarez: although the PowerColor HD 2600 Pro 512MB has two times the amount of memory of the standard model, and the game is quite a resource-consuming application, it does not have any advantages in this test. You can’t enjoy Call of Juarez fully on an inexpensive graphics card like ATI Radeon HD 2600 Pro or Nvidia GeForce 8600 GT.
Call of Juarez DX10
Of course, the results in the DirectX 10 version of Call of Juarez are no good as the average frame rate of graphics cards of the ATI Radeon HD 2600 Pro class is as low as 5fps at 1280x1024.
