Ubisoft confirms it will continue to work with NVIDIA and leverage the chipmaker's technologies for the PC ports of its upcoming lineup of core gaming titles including Assassin's Creed Unity, Far Cry 4, Tom Clancy's The Division, and The Crew. The partnership is no doubt good news for NVIDIA, which would rather have you playing these games the way it wants you to play them.
The extra graphical bells and whistles (including TXAA antialiasing, horizon-based ambient occlusion, and of course PhysX) demonstrated on the PC release of Watch Dogs were a result of Ubisoft licensing NVIDIA's GameWorks suite of proprietary visual effects, as well as the NVIDIA's habit of working with game developers to better optimize their titles on PC once they're invited to the party. This has lead to AMD crying foul over what it claims as its competitor's attempts to "deliberately" cripple the performance of major titles on AMD hardware.
To be sure, Watch Dogs on PC still suffered from notable framerate and performance issues out of the gate. It's just as well then that Ubisoft and NVIDIA will be keeping in touch for a little while longer, as both companies can certainly stand to work together to iron out these issues on current and upcoming titles.
