Our colleagues from German PCGamesHardware online magazine had a chance to talk to Oliver Baltuch and Dr. Jukka Makinen from Futuremark. They even managed to get a new 3DMark Vantage screenshot, which makes this benchmark look even more like Egosoft's X3 Reunion game.
Apart from the usual, "This has not yet been announced" sentences when asked about DirectX 10.1 and various presets, PCGH managed to get some nice info during this interview. According to the interview answers, the new 3DMark is a 32-bit application, which will run on a 64-bit OS but without any specific 64-bit optimizations. Dr. Jukka Makinen from the Futuremark has also noted that Futuremark's new 3DMark will be able to use more than 4 CPU cores, or to be more precise, "You will be able to see the benefits of multiple CPU cores well beyond 4."
