NVIDIA's lineup of Turing GPUs

NVIDIA has finally released its latest GeForce Game Ready WHQL driver which enables support for Microsoft’s DXR API on GeForce GTX GPUs. The latest driver was announced last month by NVIDIA at GDC 2019, allowing non-RTX graphics cards to provide users with the ability to render real-time ray tracing effects. With the driver available now, owners of GeForce GTX GPUs can try out the real-time ray tracing features in some of the top AAA titles.
