rHelp
Defines which implementation is used to detect the GPU driver (to check for old drivers, logs and statistics) 0: Iterate available drivers in registry and choose the one with the same name, if in question use next method (happens) 1: Get the driver of the primary adapter (might not be correct when dealing with multiple adapters) 2: Use DirectX LUID (would be the best, not yet implemented) 3: Use Windows functions, use the primary device (might be wrong when API is using another adapter) 4: Use Windows functions, use names such as DirectX Device (newest, most promising)
