ATI Radeon X1900 family

Age of Empires III

Publisher: Microsoft Game Studios

We have used the full retail version of Age Of Empires III, patched to version 1.01. The game has a wide install base, supporting everything from the latest Shader Model 3.0 video cards, such as Radeon X1800XT and GeForce 7800 GTX, right back to fixed-function video cards that supported DirectX 7.0, like the GeForce 2.

Ensemble Studios have concentrated on making the game look as good as possible - we'd argue that this is currently the best looking game on the market. The attention to detail is simply outstanding.

The developers have also implemented high-dynamic range lighting, but it appears to look more like a bloom effect. HDR allows scenes to look much more natural because the lights can be brighter and the shadows can be darker, while maintaining a high level of detail, too. Turning the "Bloom" HDR option on really makes the world look impressively dreamy and realistic.

We did a manual run through from the tutorial, followed by a skirmish in order to evaluate the real game performance at certain resolution and detail settings. We found that there was a massive performance hit from enabling Anti-Aliasing, so we have left it disabled in this case. An average of 30 fps and a minimum of 10 fps seemed to be reasonably playable through the skirmishes, which are generally pretty intensive.

Age of Empires III uses a high dynamic range lighting method to improve the look of the world. Of course, ATI's X1000-series can do both HDR and antialiasing at the same time and it's something that NVIDIA's cards can't do at the moment. When you enable antialiasing and HDR bloom on any of NVIDIA's GeForce 6/7 products, the performance drops considerably because the card is trying to render the antialiasing samples inside the pixel shader.

The Radeon X1900XTX was able to play the game very smoothly at 1600x1200 with 2x QAAA 8x HQ AF with maximum detail settings, while the GeForce 7800 GTX 512 was able to play the game at 1600x1200 0x AA 8x AF with high quality driver settings. The Radeon X1900XTX was able to play the game with a higher level of image quality and was considerably smoother too.

When we enabled CrossFire mode, we found that we were able to play the game at 2048x1536 with the same detail settings, making for a fantastic gaming experience. The lack of support for HDR lighting and antialiasing at the same time really plagues the gaming experience on the GeForce 7800 GTX 512 SLI configuration and we had to settle for 2048x1536 0xAA 8xAF with maximum details and high quality driver settings.

That's not to say that the game looked bad on the GeForce 7800 GTX 512 SLI, it just didn't look as good as it did on the Radeon X1900 CrossFire configuration. We've not seen this game look this good before and the experience was again, simply breathtaking!
