But can you integrate it into any UE4 project or installation? Or only in the custom Nvidia branch?
It would be a dream to see it integrated into UE4, or as an independent plugin. For the moment, the process is complicated and, as far as I remember, your project will show a Nvidia watermark, which will be able to be removed under some conditions (I can imagine showing the Nvidia logo at the begining of your ‘game’, at least)
