Oh dear AMD. The PCPer article they link to states expressly

So what do AMD do? The following:

*shakes head*

It makes AMD look really stupid when they do that.

My opinion is that AMD should still be able to enjoy certain benefits now though as they already have Mantle available, unless these gains will only be realised with Mantle running alongside a DX12 platform, I'd like to see a comparison that shows how Mantle under Win 8.1/DX11 stacks up against Mantle under Win 10/DX12. If I have missed that please point it out to me, or explain why that has not been addressed if it hasn't as I didn't have time to read the full PC Per article.

Shouldn't be any difference at all - Mantle is an alternative to the win/DX stack so it bypasses it.

Yup Mantle doesn't run under DirectX and the reason we need Windows 10 is because we need DirectX12 and that's going to be the first OS to get it.

As to that AMD page......I know companies like to pimp themselves but some of the BS they have written on that page is infuriating. Implying devs will have an easier time getting DX12 working on AMD cards because they have worked with Mantle?

Then "finally allows a multi-core communication lane between your AMD FX processor and AMD Radeon™ GPU".....making it sound like DX12 won't work with Intel CPUs or nVidia GPUs....

iven that DirectX® 12 will be a transformative experience for millions of gamers, it’s important that hardware vendors like AMD have a 360-degree view of the issue. Thankfully, the pervasive nature of the GCN Architecture in the games industry highlights that AMD stands alone with that perspective. - See more at: http://community.amd.com/community/a....QrClm36I.dpuf

Seriously?

It's the worst bunch of BS on a single page I think I've ever read from a tech company.

Of course, I actually knew that but for some reason it didn't come to mind when posting the question. doh...

To me this sounded like they were saying up until now there was no 'multi-core communication lane between your AMD FX processor and AMD Radeon™ GPU' but the release of Windows 10 and DX12 will finally give AMD customers access to the hardware that they were promised when GCN was first developed. I read it more as AMD admitting that they were not delivering all they could but will do when Microsoft gets their next OS out.

Sorry, Chrome/my PC or something else intervened causing my post to appear twice! If some nice mod should happen upon this then please delete this post.

Thanks.
