Brad Wardell, the CEO of Stardock, has been using Twitter to send out some neat details recently, particularly pertaining to DX12. He has said that when running a comparison between a DX11 and DX12 GPU, there was a difference of more than 100fps.
Whilst the GPU in question wasn’t named, the tweet reads, “Did a test of DirectX 11 vs. DirectX 12 on an unreleased GPU with an 8 core CPU. DX11: 13fps, DX12: 120fps. Lighting and lens effects.” One player, who proudly calls himself an Xbox One gamer, tweeted at Wardell asking if this was close to the Xbox One Specs. Wardell of course responded, “No. This is way beyond console stuff.”
While we’re not sure of the specific setup being used by Wardell, One problem that gamers who make use of multiple GPU’s often run into is having their multiple GPUs is recognised as one single setup, speaking on the matter in response to a question, Wardell says, “One thing it does is make it easy to treat multiple GPUs as a single entity.” Good news for hardcore PC gamers with big rigs.
