Now at 2560x1600 we find that almost no single graphics card can handle Battlefield: Bad Company 2. The Crossfire Radeon HD 5870 graphics cards averaged just 74fps using the high quality preset with 2xAA/4xAF. A single Radeon HD 5870 rendered 51fps, while the Radeon HD 5850 and GeForce GTX 285 barely managed to deliver an acceptable level of performance. Everything below the GeForce GTX 285 is useless at this extreme resolution with these quality settings.
Dropping the preset to medium allowed the Radeon HD 5870 to average 60fps, while the Radeon HD 5850 and GeForce GTX 285 averaged 46.5fps and 45.5fps respectively. The GeForce GTX 275 and Radeon HD 5830 just managed to render 40+ fps, while everything else situated below them was too slow to consider.
Obviously no one is going to want to game at 2560x1600 using low quality visuals, but for comparisons sake we have tested that here anyway. As you can see, the Radeon HD 4870 is as slow as you can afford to go, while a Radeon HD 4890 or faster is ideal.
