Your old AMD GPU now has unofficial ray tracing support, but not on Windows

Ray tracing is a luxurious that’s normally related to new GPU expertise. Nonetheless, because of the efforts of a Direct3D developer, older AMD playing cards can now, unofficially, get pleasure from the advantages of fancy rendering and lighting tips on Linux.

In keeping with Phoronix, developer Joshua Ashton’s has submitted a merge request that features ray tracing assist for previous generations of AMD GPUs. That is one thing that Ashton states is achieved by “emulating the AMD bvh intersection directions in software program”. Naturally, the unofficial RADV driver assist will allow ray tracing on Navi, Vega, and Polaris playing cards, however the options gained’t essentially work as supposed.

Whereas the magic of emulation is sufficient to make utilizing the drivers doable, AMD’s legacy lineup lacks bodily Ray Accelerators, one thing that’s integral to efficiency relating to ray tracing duties. Even with devoted GPU cores, the sunshine rendering approach is sufficient to make even Nvidia RTX and AMD Radeon RX playing cards sweat. That stated, Ashton’s merge request states that the method “passes CTS the identical as on RDNA 2 playing cards”, so maybe the software program resolution will yield some stunning outcomes.

Getting maintain of a brand new graphics card in 2021 is not any simple feat, so Ashton’s Vulkan port may very well be a brief various for anybody desirous to expertise ray tracing on their present rig. Nonetheless, in case you favor settings that boost fps over constancy, you’ll in all probability wish to sit this experiment out.
