Has some really nice effects like global illumination, vegetation touch bending, accurate sunlight shafts, rag dolls etc. I don't know if Amazon inherit new versions and how CIG can get there hands on them. I suspect that bridge is burt. However there's plenty of improvements here that would benefit Star Citizen, a pity that's probably not going to happen. One can only hope that Amazon does a deal with Crytech and CIG gets the option to use some of this in the future?
