AMD’s new Vega drivers give multi-GPU support

Run two Radeon RX graphics cards in Crossfire, if you can get your hands on a pair.

Good luck finding a single Radeon RX Vega graphics card in stock at a fair price, let alone two. But if you do happen to snag a couple of Vega cards, you now can configured them in Crossfire with AMD's latest Crimson ReLive driver release.

AMD's Radeon Software Crimson ReLive Edition 17.9.2 release introduces 2-way multi-GPU support for Radeon RX Vega cards, along with a multi-GPU profile for Project Cars 2, which released today.

The new driver package also fixes a couple of issues. They include:

  • Hearts of Iron IV may experience a system hang when the campaign scenario is launched.
  • Radeon Software may display an erroneous "1603 Error" after installing Radeon Software. This error will not affect your Radeon Software installation.

Multi-GPU support has become much less of a priority for both AMD and Nvidia. Traditionally adding a second graphics card to the mix has not resulted in double the performance, and in some cases running a Crossfire or SLI configuration can be problematic. It's typically better to buy the fastest graphics card you can afford, rather than a cheaper GPU with plans to add another down the line.

In this case, AMD is limiting Crossfire support on Vega to two cards. Or perhaps we should say multi-GPU support instead of Crossfire at this point—AMD noticeably avoids using the "Crossfire" terminology in its release notes, underscoring the lack of interest in attacking framerates with multiple GPUs.
