Gamers are so easily swayed by the marketing hype. So, AMD has a new processor tech and they are saying that it makes everything better if you use it. Did anyone expect them to say that their new advertising slogan of hUMA is garbage and doesn't help performance? AMD/Intel are always saying some crap about how their new "tech" is going to revolutionize the power of the gaming/pc world. All of these ideas take years for developers to even take a look at, as they would have had to plan for that at the beginning. Even if they had some plan to do so, do you think that the code writers were instant experts at do it? Also, if you assume that these capabilities do enhance the capability of their processor, has it been studied or used by enough people to determine if there is some type of trade off being made. The short answer is Probably Not or No.
New processor tech takes years to be implemented into the software and unless Intel is doing the same, won't be implemented at all. The reason is that almost everyone of these games(even first party) will be ported to another system or PC at some point. If you write the program with too little or no ability to use or not use a tech that is implemented in so few machines, you are throwing away a shit ton of $$$ long term. Developers know that games last forever now. It can be released on one system and years later released to all systems via digital downloads.
Bottom line = Don't fall for the PR B.S.
