Earlier, it was reported that AMD would join the support of RSR technology for GCN graphics card users 10 years ago to easily achieve a three-fold performance improvement. According to the source code of radeon Vulkan's new driver rAdV, AMD is not satisfied with adding RSR technology to GCN, but plans to add Vulkan ray tracing driver support**
Although it will be relatively difficult to run light chasing on old graphics cards without independent units, it can also improve the picture quality and bring a better game experience.
At present, some users have tested the update. In some development projects that need to use ray tracing, the addition of this technology can greatly improve the use experience:

The test of independent developer Konstantin seurer shows that in the gravitymark benchmark test, the GCN graphics card with radeon rAdV lbvh patch has improved its running speed from the original 13fps to 250fps, with remarkable results**
However, it should be noted that at this stage, the compatibility of many games with this update is not ideal , and it will take some time to get a better game experience.
