I use Cinema 4D and have a Ryzen 5959X CPU coupled with a RX 6800 XT, I have read that ProRender is supported on 6000 series graphics cards, however, I can not seem to get Cinema 4D to show the ProRender as displayed in the Cinema 4D info on the AMD ProRender article
The text from the AMD ProRender
Next-Generation Rendering
Now uses Radeon™ ProRender 2.03 with an improved rendering algorithm and support for hardware-accelerated ray tracing on AMD Radeon™ RX 6000 Series graphics.
