Nvidia Clarifies - RTX in games doesn't just mean Ray Tracing
At their Geforce Gaming Celebration before Gamescom 2018, Nvidia announced that a total of 21 games would support Nvidia's RTX technologies, a feature that was almost exclusively marketed as Ray Tracing support at the show, with examples like Battlefield V, Metro Exodus, Atomic Heart and Assetto Corsa: Competizione all featuring support for real-time Ray Tracing.
Now that the dust has settled a little, Nvidia has released a press release to confirm that RTX technology refers to both AI and Ray Tracing, which means that almost half of the "RTX Games" below will lack any support for Ray Tracing. In fact, more of the titles below support Nvidia's AI-driven DLSS (Deep Learning Super Sampling) than real-time Ray Tracing, with 16 games supporting DLSS while 11 support Ray Traced elements.
