Scores follow the conditions in the table above, and the rank is based on an average in which "Realism and depth" counts double. The basis is official manufacturer information. Sound quality and CPU load are not measured, so they are not scored; reviews from trade magazines are introduced in the articles for reference. Price is not part of the score.
