Yes, Nvidia is finally moving on from its GTX naming convention after a decade, while also jumping from 10-series to 20-series cards. RTX refers to real-time ray tracing, a computationally expensive process of accurately modelling how light bounces between reflective surfaces in a scene. Ray tracing in real time has been a holy grail for graphics card makers for years, and it looks like Nvidia has become the first to truly crack this photo-realistic lighting effect.

Nvidia is promising ray tracing performance which is six times faster than previous generation graphics hardware, thanks to dedicated RT cores. Nvidia replayed the Star Wars short they released at GDC in March, and CEO Jensen Huang stated that the four Volta V100 data centre GPUs used to originally render the short are outperformed by a single consumer-grade RTX 2080 Ti - impressive stuff.

In order to allow game developers to make use of Nvidia's real-time ray tracing tech, Microsoft and Nvidia developed the DirectX Ray Tracing (DXR) API. Epic are set to add real-time ray tracing support for Unreal Engine 4 developers by the end of the year, and other large game engines are also expected to announce support for RTX in the weeks to come.

Nvidia also showed off some of the first titles with real-time ray tracing support at the event: Metro Exodus, Battlefield V and Shadow of the Tomb Raider. Metro Exodus is a February 2019 title, while the other two games are set to debut this autumn. The number of RTX games by next year should be considerable, with Nvidia highlighting 21 titles at the event including both existing and forthcoming releases. We won't list them all here, but some big titles included PlayerUnknown's Battlegrounds, Mechwarrior V: Mercenaries and Final Fantasy XV.
