If you own a Radeon-based video card, you should head on over to AMD's website and download the new Radeon Software Crimson ReLive Edition 17.9.2 driver.
These new drivers offer up Radeon RX Vega multi-GPU support (up to 2x) as well as a new multi-GPU support for the upcoming launch of Project CARS 2. According to the release notes, Radeon Software may display an erroneous "1603 Error" after installation.
