Your arbitrary definitions mean nothing. A blockbuster is something of great success and there are many AAA games that are blockbusters that aren't GTA, COD or FIFA A lie. The point: similar architectures are easier to work between that ones are that are very different. Wrong. You're losing track of the conversation. People that buy just one game for a system are in the minority. System sellers usually bring users into the platform who then buy more games. GT is a system seller. I'm sure they have already implemented classes and such for the objects. Wouldn't be hard to assign objects into groups from there depending on material and such. Coming from the guy whose posts had zero basis in reality via data, and then when presented with data had no reply this is expected. Yes but unlike light ray tracing sound ray tracing is not physically accurate. Sound is a pressure wave and cannot be modeled accurately as a particle. It could still be great for video games though.
