Me too. Big names in the gaming industry have spoken out against Gameworks (John Kloetzli - Firaxis, Bart Wronski & Michal Drobot - Ubisoft Montreal, Timothy Lottes *an ex-nVidia employee*- Epic, Johan Andersson - DICE) and there is
flat out proof that the platform
favours Nvidia cards because
AMD are unable to access the source.
Because of how minimal these changes look, I think it won't be much of a problem. However I would be a lot more comfortable with them choosing an open platform to allow myself and the other 40% of the GPU market to get the most out of their systems in this game for the foreseeable future.
