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 index 0!)

  • 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
