Early in-game benchmarks using DirectX 12-compatible game ''[[Ashes of the Singularity]]'' showed slight performance gains on the [[GeForce 900 series|Nvidia GeForce 980 Ti]] card tested, and major performance gains over DirectX 11 on [[AMD Radeon Rx 200 series|AMD Radeon R9 290x]]—with average frame rates nearly doubled in extreme cases, meeting or even exceeding the performance of the Nvidia card tested (by contrast to the Nvidia card, which outperformed on DirectX 11 benchmarks).<ref name="arsuk-dx12bench">{{cite web |url=http://arstechnica.co.uk/gaming/2015/08/directx-12-tested-an-early-win-for-amd-and-disappointment-for-nvidia/ |title=DirectX 12 tested: An early win for AMD, and disappointment for Nvidia |work=Ars Technica UK |author=Walton, Mark |date=August 19, 2015 |accessdate=August 19, 2015}}</ref>
