Real-time ray tracing will no longer be an exclusive feature of Nvidia GeForce RTX graphics cards next month. GeForce GTX accelerators will receive support for this technology with the release of a new driver, Nvidia representatives said at the GDC 2019 conference.
Both the owners of the new GeForce GTX 1660 and 1660 Ti and the users of the previous generation of 3D cards based on the Pascal architecture will be able to activate DirectX Raytracing in games. Unfortunately, due to the lack of RT cores, the speed of ray tracing on these video cards will be low. So, in Shadow of the Tomb Raider, the GeForce GTX 1080 Ti graphics accelerator is twice as fast as the RTX 2080, and in Metro Exodus, the gap is already threefold.
In the near future, the popular game engines Unity and Unreal Engine will also acquire DirectX Raytracing support, which will contribute to the widespread adoption of the technology.
