It's nice when companies lie to you to get your business, isn't it?
We tried to duplicate the screen shots that ATI supplied to us, and found that ATI seems to have misrepresented the micro-geometry detail of NVIDIA's 8X anti-aliasing method. The screen shots we took on our own with a GeForce 6800 GT, clearly show more detail than the screen shots distributed by ATI in their CrossFire presentation.
Finally, we contacted ATi for comment on this issue that we discovered and they agreed they too could not reproduce the lack of detail that is represented in the NVIDIA screen shot they provided us above, although they assured there was no intention of misleading us with these competitive image quality comparisons. This isn't the first and probably won't be the last time we will be witness to over-zealous marketing efforts, whether accdidental or intentional.
