Nvidia yesterday introduced the RTX technology. This technology will finally allow you to implement in games, ray tracing in real time. This is an alternative to the usual methods of rendering technology of imaging, which involves tracking back the trajectory of the beam propagation (from the screen to the source).
About this technology to say for a long time, but the performance of consumer hardware solutions were insufficient to implement ray tracing in real time, which is necessary for games.
And that Nvidia RTX needs to change. Technical details are almost there. We know that the developers when working with RTX can only use graphics cards with the architecture of the Volta. At the moment these include one model of a family of Tesla and Titan V. If you believe the rumors, soon to be joined and adapters Quadro.
As for software, Microsoft presented DirectX API Raytracing (DXR), so that all functions will be available through it. And this in turn means that directly in game using the technology of RTX can be played on the PC, which will be equipped with graphics card other than the generation Volta. However, that will in this case performance, while we can only guess.
It is also reported that some companies have already worked with the technology before it was announced. A list of them you can see in the image below.
In the set of GameWorks in beta versions already available and new tools for working with the technology of ray tracing. But when to wait for the first games with RTX, is unclear. However, during the announcement of Nvidia representative hinted that the company expects the first games this year, but the press release is not horrible, and mentioned that not all the sources, so that rolled lip is not worth it.
