I think all AMD and Nvidia GPUs support 1.1 given they have updated driversCBJ wrote: ↑Sat, 26. Jan 19, 18:38Up to now we've not specified a particular version of Vulkan, and supporting SLI would mean we'd have to require Vulkan 1.1 for everyone. Not only that but because of the nature of Vulkan, we'd have to do all the work of supporting multiple GPUs; work that is done almost entirely by the drivers when using other APIs. So, this is a tricky one and we can't make any promises on it.Cinderelli wrote: ↑Sat, 26. Jan 19, 18:26Thank you for posting this roadmap. Unlike other game developers, you are keeping your player base informed. Kudos to your whole team.
Could you please clarify if we will ever get multiple GPU support? There are many of us running SLI setups that want very much to play this game with the full utilization of both of our graphics cards.
so even if I pick an old Nvidia GT 630 and have a driver 4220.127.116.11 or higher installed, you will have for example Vulkan 1.1.82 capabilities.
According to this page even some Intel based GPUs would support 1.1
From a programmers perspective: The support check for the all GPUs in the system (regardless of SLI or not) you probably already have in place (checking supported queue families etc.). All you really have to do is setting up a device group.
And from here everything is abstracted anyways, as you only deal with logical (sub-)devices thereafter. So for executing command buffers for example you really don't need to do much different, as the drivers will take care of where to execute it.
