No, it is an impossibility.
Well, not an absolute impossibility, but the idea is so unfeasible once you think about it that it's just not going to happen.
Basically, it's like this. The Radeon 9700 and the GeForce line calculate the anisotropic degree in different ways. The GeForce line of cards uses a smooth function that gives the same result regardless of angle (I can't be certain if nVidia elected to use the proper function, or just a smooth approximation), whereas the Radeon 9700 uses a different function entirely that appears to be based upon absolute values.
What you should get from this is that the same hardware simply cannot be used to compute the degree of anisotropic for both cases, so supporting both would be idiotic as it would require specialized hardware for each case.
exactly ,it will be nice if websites show in reviews
slowdowns in framerates and artifacts errors , lately ,TomsH
latest review of the Geforce4 mx-agp 8x vs radeon9000
(a very good one) shows graphs that tells the worst performance
case for both cards ..
It would be nicer if they would release statistic based on the framerate information such as standard deviation, which is a measurement of how much the data varies from the mean (average) framerate. After all, just showing the minimum or showing the number of significant drops in framerates are both very subjective measures. A standard deviation is very objective and would give a very good idea of how stable the framerates are.
