AMD RADV Vulkan Ray-Tracing LBVH will support for all AMD GCN GPUs
Recently, the Mesa library has updated the source code of the Radeon Vphoroniulkan driver RADV, which enables some older AMD graphics cards to support Vulkan’s ray tracing capabilities at the driver level. According to Wccftech, this version of the driver currently supports GFX6, which is a component of the GCN 1.0 architecture. Ray tracing can be very hard to run on older graphics cards without dedicated units, so don’t expect too much, just say something is better than nothing.

Independent developer Konstantin Seurer found that in certain workloads (such as the GravityMark benchmark), the running frame rate has been increased from 13FPS to 250FPS, and the effect is still obvious. AMD’s support for older hardware in Linux is really surprising. You know that last month, the latest Mesa 22.2 library only supports AMD RDNA architecture GPUs, and AMD’s focus on ray tracing is still on the RDNA2 architecture. However, this version of the driver seems to be less than ideal for game compatibility, and players are best not to try it casually.
There was also news that AMD intends to support Radeon Super Resolution (RSR) technology on GCN architecture GPUs so that these old graphics cards can get performance improvements when running games. At present, Radeon Super Resolution only supports RDNA and RDNA 2 architecture GPUs, and Ryzen 6000 series APUs. Compared with a large number of GCN graphics card users, the number of users is much smaller. In addition, even the RDNA architecture graphics card still has good performance, and the demand for Radeon Super Resolution is not urgent.
