Performance in Third-Person 3D Shooters

Devil May Cry 4

Only AMD/ATI solutions win from the transition to Windows 7. Namely, the average performance of Radeon HD 4890 improves by 5-7% depending on the resolution. The readings off the dual-processor Radeon HD 4870 X2 increase by about the same number, except 1280x1024 resolution, where something else not connected to the graphics card specs, must be limiting the performance of this accelerator.

Like in most other cases, installing Windows 7 instead of Windows Vista provides minima performance boost of only 2-4%. Nothing has seriously changed in the minimal performance levels, either. I would like to stress that Radeon HD 4870 X2 did lose some speed in 2560x1600 and ran almost 3% slower.
