Call of Duty: Warzone. Image: Infinity Ward/Activision Nvidia and Epic Games have taken what could prove to be an important step in the long road to bringing ray-traced video game graphics to the masses. Last week, Nvidia released a plugin for Epic’s Unreal Engine 4 that will enable developers to implement the chipmaker’s Deep Learning Super Sampling (DLSS) technology in their games much more easily than before. Until now, developers have had to work with Nvidia to add DLSS to their games. That’s one reason why the technology has been limited in its use — it’s available in only 25 or so games at the moment, although the makers of more than a dozen others have announced plans to add DLSS support.
