Call of Juarez

Originally released in 2006 as a DirectX 9 application, Call of Juarez is ready to acquire DirectX 10 support to improve its visual appeal and add new special effects.

To be specific, the demo version of Call of Juarez DX10 features the following improvements:

• Improved HDR lighting model
• Adaptive software FSAA
• Improved vegetation
• Improvements in pixel shaders (for a more accurate physical model of the behavior of particles)

The list is short despite the considerably larger amount of work for the developer. The difference between the DirectX 9 and 10 implementations is noticeable to the eye, though.

After the release of the Call of Juarez DirectX 10 performance test Nvidia pointed at the developer’s not using the hardware resources efficiently, which led to lower speed of Nvidia’s GPUs that they could potentially provide. Particularly, Nvidia does not approve of the use of software FSAA resolve because the GeForce 8800 has hardware units for that purpose.
