AMD RDNA2 – Support for Raytracing & Variable Rate Shading
Microsoft has already laid out the development framework for Raytracing through the DirectX Raytracing, or DXR, API, and should be a main development tool for game developers working to implement raytracing within the upcoming [AMD Powered] Xbox
Variable Rate Shading, or VRS, is another feature to be included within AMD's RDNA2 GPUs.
gamers may expect to achieve increased playability at 4K resolutions and beyond.
As we know, Nvidia GPUs already have a version of Raytracing and a version of Variable Rate Shading. For it to really work requires a high end (expensive) GPU to be useful at 4K.
Since AMD's versions are expected to run well on a relatively inexpensive console (and a PC), it will be interesting to see if they've found a way to make it faster/cheaper than current Nvidia RTX.
