The game has been out for awhile (and the benchmark, too). At this time, a Japanese version and a Chinese version of the game are available.
According to E3, English version will be available?

P.S. there are quite a few settings you can customize in teh benchmark for options like shadow, "many stuff" detail level, AA, AF etc.
