Hi @Anonymous, unfortunately older generations of hardware do not allow to unleash the full potential of certain games, this is why more and more games will come to Next-Gen and PC only in the future. The release date of NFS on PC has been moved to Spring 2016 for that same kind of reason. This is what the team at Ghost said about that:
Part of the conversation includes hearing from our PC community that an unlocked frame rate in Need for Speed is a massive priority for you, and we fully agree. To deliver this, we’ve made the decision to move the PC release date to Spring 2016. Our PlayStation 4 and Xbox One release dates will remain the same, starting November 3, 2015 in North America and November 5 worldwide.
This decision on PC gives us the necessary development time to increase the visuals that we can deliver on PC. We will also include content updates that will have been released on console up to that time, making them available to all PC players from day one.
