Far Cry 2 Benchmark

Ubisoft has developed Far Cry 2 as a sequel to the original, but with a very different approach to game play and story line. Far Cry 2 features a vast world built on Ubisoft's new game engine called Dunia, meaning "world", "earth" or "living" in Farci. The setting in Far Cry 2 takes place on a fictional Central African landscape, set to a modern day timeline.

The Dunia engine was built specifically for Far Cry 2, by Ubisoft Montreal development team. It delivers realistic semi-destructible environments, special effects such as dynamic fire propagation and storms, real-time night-and-day sun light and moon light cycles, dynamic music system, and non-scripted enemy A.I actions.

The Dunia game engine takes advantage of multi-core processors as well as multiple processors and supports DirectX 9 as well as DirectX 10. Only 2 or 3 percent of the original CryEngine code is re-used, according to Michiel Verheijdt, Senior Product Manager for Ubisoft Netherlands. Additionally, the engine is less hardware-demanding than CryEngine 2, the engine used in Crysis.

However, it should be noted that Crysis delivers greater character and object texture detail, as well as more destructible elements within the environment. For example; trees breaking into many smaller pieces and buildings breaking down to their component panels. Far Cry 2 also supports the amBX technology from Philips. With the proper hardware, this adds effects like vibrations, ambient colored lights, and fans that generate wind effects.

There is a benchmark tool in the PC version of Far Cry 2, which offers an excellent array of settings for performance testing. Benchmark Reviews used the maximum settings allowed for our tests, with the resolution set to 1920x1200. The performance settings were all set to 'Very High', DirectX 9 Render Quality was set to 'Ultra High' overall quality, 8x anti-aliasing was applied, and HDR and Bloom were enabled.

Although the Dunia engine in Far Cry 2 is slightly less demanding than CryEngine 2 engine in Crysis, the strain appears to be extremely close. In Crysis we didn't dare to test AA above 4x, whereas we used 8x AA and 'Ultra High' settings in Far Cry 2. The end effect was a separation between what is capable of maximum settings, and what is not. Using the short 'Ranch Small' time demo (which yields the lowest FPS of the three tests available), we noticed that there are very few products capable of producing playable frame rates with the settings all turned up.

At 1680x1050 the Radeon HD 4890 performs at 30.7 FPS while the factory-overclocked GeForce GTX 285 scores 32.8, presenting the argument that a reference-speed GTX 285 might possibly match performance of a Radeon HD 4890. The point is driven home when the 1920x1200 resolution pegs the reference Radeon HD 4890 nearly matching the GTX 285. Everything else beneath these products seems incapable of producing the required performance to keep motion fluid and lifelike. When there's a strain on the graphics, like Benchmark Reviews has created in the Far Cry 2 tests, the RV790 and GT200 GPU's appear to be the ideal graphics solution.

Our last benchmark of the series is coming next, which puts our collection of video cards against some very demanding graphics with World in Conflict.
