AMD is preparing Radeon gamers for Prey with the release of the new Radeon Software Crimson ReLive 17.5.1 beta drivers, which even include some performance optimizations for the just-released Radeon RX 580 graphics card.
The new drivers feature a decent 4.7% performance boost for the RX 580 in Prey, but they also provide multi-GPU support for CrossFire owners who want to see additional performance from their RX 580 CF rig. There are the usual bug fixes and improvements in these new drivers as well, and AMD has also patched their auto updater so it no longer fails.
You can grab the new 17.5.1 drivers right here.
