john_ It doesn't make games run slower or look worst on Nvidia cards. We are not talking about PhysX here. Nvidia users lose nothing in visuals or performance.



In the first presentation of Mantle's advantages over DirectX 11 in AoTS, AMD was using a system with an FX 8350 clocked down to 2GHz.

Lol, Vulkan isn't "biased". AMD GPU's are just more advanced when it comes to more direct GPU access (that Vulkan and DX12 allow), the fact they weren't shining is because software wasn't taking any advantage of all that yet. Till now. I mean, AMD had partial async compute since HD7000 series and full in R9 290X. NVIDIA still doesn't have even partial in GTX 1080 from the looks of it. Async is when you ca seamlessly blend graphics, audio and physics computation on a single GPU. Something AMD was aiming basically the whole time since they created GCN. They support graphics, they've added audio on R9 290X and they've been working with physics for ages, some with Havok and some with Bullet.R9 Fury X users don't feel that let down anymore :P In fact R9 Fury cards in general shine in DX12 and apparently also in Vulkan. While I love my GTX 980 I kinda regret I haven't gone with R9 Fury/Fury X.Also, for people saying "async emulation", there is no such thing, either you have hardware implementation or you don't. You can't emulate a feature that's sole purpose of it is massive performance boost through seamless connection of graphics and compute tasks. This is the same as emulation of pixel shaders when they became a thing with DirectX 8. Either you had them or you didn't. There were some software emulation techniques, but they were so horrendously slow it just wasn't feasible to use in real-time rendering within games. Async is no different. And NVIDIA apparently doesn't have it. Which kinda sucks when you pay 700+ € for a brand new graphic card...I guess that's how NVIDIA fanboys are comforting themselves after buying super expensive GTX 1000 series graphic card (or GTX 900) that sucks against last generation of AMD cards that weren't particularly awesome even back then. "uh oh it doesn't lose any performance". Well, you also gain none. What's the point then? The whole point of Vulkan/DX12 is to boost performance. When devs will cram more effects into games assuming all these gains, your performance will actually tank where AMD's will remain unchanged. How will you defend NVIDIA then?
