World in Conflict

Publisher: Sierra

We regard World in Conflict as one of the best real-time strategy games we've ever played. It's based on Microsoft's DirectX 10 API and, in collaboration with Nvidia's The Way It's Meant To Be Played developer support team, it incorporates some DirectX 10 specific graphics effects.

The first of these is a soft particle effect that removes the banding often found in particle effects like smoke, explosions, fire and debris - the effects simply didn't exist in the 3D world; instead, they were merely an add-on. With DirectX 10, the edges of the particle effects are much softer and banding is almost non-existent as the effects now interact with their 3D surroundings, as they're actually a part of the 3D world.

Additionally there are global cloud shadowing and volumetric lighting effects in the DirectX 10 version of the game. The latter is often referred to as 'god rays' and its implementation in World in Conflict interacts with the surroundings incredibly well. On the other hand, the former is where clouds cast shadows on the rest of the environment and, because all clouds in World in Conflict are volumetric and dynamic, the shadows cast by the clouds are rendered dynamically in DirectX 10 - they adjust in relation to the size, shape and orientation of the cloud in relation to the light source.

For our testing purposes, we used a full retail copy of the game and patched it to version 1.002, which boasts some improved performance under DirectX 10. We used a manual run through from the Invasion level, which incorporates all of the effects we've discussed above. We chose not to use the built-in benchmark because it's largely CPU-limited. We used the "very high" preset, and controlled anti-aliasing and anisotropic filtering via the advanced settings tab.





As with Crysis there was no CrossFire scaling in this title either. Thankfully, as we pointed out in our GeForce 8800 GT review, AMD is aware of this issue and we're waiting for a fix to arrive. With that out of the way, the Radeon HD 3870 performs very well compared to the Radeon HD 2900 XT it's replacing, however it's unfortunately not enough to best the GeForce 8800 GT 512MB, which turns out to be around five frames per second faster than a single Radeon HD 3870 at 1920x1200.
