for improving rating calculation method.
We have made significant changes to the rating calculation method for several reasons. Firstly, there was a number of math errors, so we decided to use geometrical average for all test results. Secondly, the quality value had little to no influence on the results. This was unacceptable due to newer games, in which AA or AF are very important. Thus we made AA and AF influence floating. The geometrical average performance is divided by 60 FPS (as a standard of average minimal sufficient performance) to obtain a coefficient of suitable performance. It's multiplied by a pre-fixed AA or AF coefficient that depends on certain card specs. This gives us a coefficient of card's AA or AF potential, that we finally take into consideration. Otherwise top-end cards would be underestimated, because when you spend $400-500, you get not only the FPS in existing games, but some potential for some higher quality in the future. Otherwise $10 cards made in 2002 could get high marks due to their low price).
Usability ratings are calculated by the following formula:
The similar calculation (just for the 1600x1200 resolution) indicates
the prospect of a videocard. The formula contains the same indexes
as those used for usability rating calculations, but accelerator's
price isn't considered. So, this rating indicates the capabilities
of the current
You can also compare two ratings to see the correspondence of product prices to their capabilities and features.
Poss is calculated by the following formula:
P.S. We understand that such way of making ratings is not perfect, therefore we await suggestions and comments from our readers to be considered in our next 3Digest.
