Does anyone know what graphics cards support Vulkan device groups. I want to try out the device group feature of vulkan but I don’t know which cards will show up when I call vkEnumeratePhysicalDeviceGroups. The answer might be different for Windows and Linux. Honestly I’m fine using either I just want to see what the performance looks like. With PCIe 4.0 we have about half the bandwidth not being used because games were tuned for 3.0 so the rest might be available for communication between cards.
