AMD fanboy look for so many excuses and conspiracy theories to blame NVIDIA for why AMD can't cope effectively with current games.
Some of these ideas might be true, BUT, I think that the biggest issue slowing AMD graphics driver team down is the size of the team. They just don't have the financial power to invest in a team as large as NVIDIA's. Better technology or not, the bottom line is still the same, many games run slower in AMD cards. AMD people criticizing GameWorks should be aware that is does pack visual benefits, at least to mainstream+ cards. The Witcher GameWorks worked wonderfully for me running a GTX 970 (EVGA factory overclocked FTW edition) @ 1080P (almost totally maxed out settings at FPS ~50). So cry and look for excuses and other companies to blame, this technology is real and it does have its advantages.
True, it does use technologies NVIDIA cards are built with and optimized for, but why won't NVIDIA do that? Why should they hold back on the features just because AMD hasn't invested in these technologies (as in purchasing PhysX) when they could give their customers a better experience by fully utilizing their cards hardware?
So yeah, you can be a biased fanboy and down rate this post, or you could consider my words logically.
