Automatic GPU Selection

• 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.
