According to the recent news, Fallout 4 will use the several technologies available in the library of NVIDIA GameWorks. At the moment the news is very interesting that neither Bethesda nor the Green camp so far not informed about any cooperation, and on the official website of Santa Clara you will not find any information about it.
Fallout 4 coming with PC Exclusive NVIDIA GameWorks
Fallout 4 is one of the hottest titles for this year. In recent times, Bethesda very actively promoted this production, presenting, among others an interesting series of videos on the SPECIAL system. The game will arrive on the market by November 10th of this year and will be available for the PC, PS4 and Xbox One.
Portal says that that has obtained information indicating that Fallout 4 is to use NVIDIA GameWorks. These technologies will include ambient occlusion, HBAO + to shadowing and lighting effects. It is not yet clear whether the green technologies will be available in the Fallout 4 for the premiere, or will be made available at a later patch.
For now this news is strange to me as NVIDIA has not revealed any information about working with Bethesda. It is hard to say that the information on WCCFTech may be true. According to NVIDIA PCGH cooperation with Bethesda it is possible, as suggested even a special competition for Fallout 4, available on the greens. However, at this time the whole should be considered as a rumor.
