NVIDIA: "NVIDIA has a long standing relationship with Techland and their publisher Ubisoft. In fact, the original European version Call Of Juarez that was launched in September 2006 is part of the "The Way Its Meant To Be Played" program. As a result of the support Techland and Ubisoft receives for being part of the "The Way Its Meant To Be Played" program, NVIDIA discovered that the early build of the patch that was distributed to the press has an application bug that violates DirectX 10 specifications by mishandling MSAA buffers which causes DirectX 10 compliant hardware to crash. Our DevTech team has worked with Techland to fix that and other bugs in the Call of Juarez code.Benchmark testing for reviews should be performed with the latest build of the game, one that incorporates those DirectX 10 fixes. Previous builds of the game should not be used for benchmarking with or without AA. For details on how to get the patch and for further information please contact Techland or Ubisoft."
AMD: "Today Nvidia is expected to host new DirectX 10 content on nZone.com in the form of a “Lost Planet” benchmark. Before you begin testing, there are a few points I want to convey about “Lost Planet”. “Lost Planet” is an Nvidia-sponsored title, and one that Nvidia has had a chance to look at and optimize their drivers for. The developer has not made us aware of this new benchmark, and as such the ATI Radeon driver team has not had the opportunity explore how the benchmark uses our hardware and optimize in a similar fashion. Over the next little while AMD will be looking at this, but in the meantime, please note that whatever performance you see will not be reflective of what gamers will experience in the final build of the game."
