GPU selection mechanismΒΆ
In Vulkan API, the word physical device is a more general word for all types of graphics cards, integrated gpus and more
If multiple physical devices are available on the system, Inexor engine is able to pick the most suitable one automatically
The user can specify a preferred graphics card index with the command line argument
--gpu <index>
(starting with index0
!)If a preferred index is specified, the engine will verify if the index is valid and pick the physical device if it is suitable
If the physical device specified by the user is not suitable because of technical reasons, automatic selection rules apply
The engine calculates a score for every available physical device based on the device type and total video memory size
If no physical devices are available or no suitable physical device could be chosen, an exception is thrown
