MGPU Guide & Discussion

Ashes of the Singularity supports DirectX 12's explicit multi-GPU feature to increase performance by taking advantage of two video cards of different model, or even manufacturer. Keep in mind, this is brand new tech and is expected to work primarily with cards of similar performance characteristics.

Here are a few tech news benchmarks of the performance you can expect:

• anandtech
• techspot
• guru3D
• Overclock3d

This is a brand-new feature that Ashes of the Singularity is the first to support, so there are bugs to be worked out. A few things to keep in mind:

• For best performance, disable Crossfire/SLI directly in the AMD or Nvidia Control Panels
• Do NOT enable MGPU if you only have one dedicated video card. Pairing a dedicated card with an integrated card is very unstable
• It is unlikely to work well when mixing low and high-end cards (the low end card will just slow down the high-end). We're still discovering what mis-matched combinations start to give useful performance gain, so we'd love to hear your results below!

If you do turn MGPU on and it crashes on launch, you can recover by running the DX11 version once, then re-trying the DX12 version. This will disable MGPU in the options.
