Performance in First-Person 3D Shooters

Aliens vs. Predator

It’s like nothing has changed over the past two years. The rebranded card outperforms each of its opponents and even challenges the more advanced Radeon HD 6850. The PowerColor delivers 30 fps at the lowest of the tested resolutions, being only inferior to the more expensive HD 6850 and GeForce GTX 560 Ti. The same goes for the popular Full-HD resolution except that the GeForce GTX 550 Ti gets very close there. Unfortunately, even overclocked, the PowerColor PCS+ HD6770 Vertex II cannot deliver a playable speed at 2560x1600 with FSAA due to its narrow memory bus.

Battlefield: Bad Company 2 Vietnam

The PowerColor falls behind the GeForce GTX 560 Ti but otherwise feels quite at ease in this game. It can’t deliver 60 fps but its main opponent GeForce GTX 550 Ti can’t do that, either. Overclocking makes the PowerColor equal to the Radeon HD 6850. Although you have to disable FSAA to ensure a comfortable frame rate at any of the tested solutions, the RV840-based products are surprisingly good compared to their opponents even in 2011.

Call of Duty: Black Ops

The PowerColor PCS+ HD6770 Vortex II exceeds the requirements of the game engine. You can set any resolution, leave the game options at their maximums, and even enable FSAA, and still enjoy a playable frame rate with the PowerColor card. The GeForce GTX 550 Ti and GTS 450 go neck and neck with each other and are both slightly inferior to the Radeon HD 6770. The RV840 developer team really has something to be proud about.

Crysis 2

Crysis 2 is rather indifferent to GPU and memory overclocking irrespective of the graphics card architecture. You'll have to disable some graphics options in order to play it comfortably on a PowerColor PCS+ HD6770 Vortex II. On the other hand, the PowerColor is quite competitive and can perfectly satisfy an undemanding user.

Duke Nukem Forever

Duke Nukem Forever is the ideal platform for showcasing the benefits of factory overclocking. The increased memory bandwidth and GPU frequency help the PowerColor card get very close to the Radeon HD 6850. The GeForce GTX 550 Ti is just as fast, though.

Metro 2033

This game is tested with the tessellation option turned on.

Our overclocking brings some benefits at 1600x900, but the PowerColor slows down at the higher resolutions. It cannot overtake the Radeon HD 6850 but leaves the GeForce GTX 550 Ti and GTS 460 behind. The frame rate is about 30 fps, which is not high for a fastidious gamer, yet the Radeon HD 6770 is the fastest card in its class here.

S.T.A.L.K.E.R.: Call of Pripyat

This game runs with enabled tessellation.

Working at its default frequencies, the PowerColor card is inferior to Nvidia's solutions, but overtakes the GeForce GTX 550 Ti after we overclock it. Unfortunately, graphics cards of that class cannot make this game playable at 2560x1600.
