At GDC, AMD, Nvidia, and Microsoft all announced their embrace of a new gaming technology, real-time ray tracing.
Under the current system, the game uses rasterization technology, which is characterized by its high efficiency. It can calculate light and shadow with very few computational resources, but its disadvantage is that it is far from the photo level.
And 'light trace' It is used by many Hollywood movies, but it takes a few hours to process a frame.
This is not a photo
AMD said that its ProRender rendering engine and Radeon GPU Analyzer 1.2 will introduce this new technology for developers to use.
At the same time, Microsoft announced the DX12 DXR, a feature suite (API) that provides accelerated light and shade calculations. As long as developers are willing, all hardware supporting DX12 can enjoy new technologies in the future.
Finally, NVIDIA launched RTX technology, which is a new GameWokrs special effect. However, it only supports Volta and updated graphics products. That is, only existing TITAN V game products can be used early. It is worth mentioning that NV's RTX Compatible with Microsoft's DXR.
At the GDC, Remedy also announced a video that uses the Northlight engine and integrates NV RTX technology. The light and shadow effect is outstanding.
