I recently ditched my Radeon 6570 on my CRT PC in favor for an R7 240, specifically to gain Vulkan support because it is GCN. I removed the old drivers with the AMD utility and installed the new ones for GCN cards. No problems at all.
I still can’t get emulators which utilize Vulkan backends to work, they simply won’t start when choosing Vulkan. They boot no problem with OpenGL though. I know typical graphics drivers automatically include drivers for Vulkan, is CRT emudriver no different?
