DX11 and AMD Crossfire Support in Windows 7 / 8.1.

Why is there no support for AMD Crossfire in Ashes of the Singularity for Users who do not want Windows 10?

Why is there no support for AMD Crossfire in Ashes of the Singularity for Users who do not want Windows 10? 

Can we please have an AMD Crossfire profile for Windows 8.1 / 7 Users who are limited to DX11 in Windows 7 / 8.1?

I have AMD HD 7970/R9 280x in Crossfire.

I am unable to get Ashes to run in Crossfire mode.

I do not have the option to run Ashes on DX12 so I can access multiGPU. 

Are you going to at least port the game to Vulkan so I have an alternative to DX12 Windows 10 to acess multiGPU?

Please advise.

I can only get 26 FPS on Crazy 1080p with 1 GPU. Good Crossfire Scaling should get me up to around 50 Fps with my current setup which would be acceptable to me.  

Thanks

You should speak to AMD, they are the one's who make crossfire profiles for DX11 games, not the developer.

I think they will have a Vulkan port eventually but it is likely some time off.

Thank you for your reply. 


I thought that work to produce Crossfire Profiles would need to involve both AMD and the developers.

I will post to the AMD Forum as you request.

Thanks.

I think Devs can program a game with an SLI/CF profile in mind but it is the driver maker who makes it happen. I've heard that Nvidia lists Ashes as having a DX11 SLI profile but I don't know if it actually works.

I hope Vulcan comes sooner rather than later too, it will be interesting to see what it brings to the table.

Thanks again for your response. Vulkan should offer performance improvement versus DX11 plus native MultiGPU support without "Crossfire" similar to DX12. 

In addition Vulkan not tied to Windows 10. So if you value your privacy / data you can stay on Windows 8.1 (Provided you are careful and watch which "Updates" get applied). Vulkan should also run perfectly well on Steam machine / Linux. 

Vulkan is already here for DOTA2. I have tried it and I am looking at the performance improvements at the moment. 

It is supposed to be available for Doom 'soon'. I tried the Doom Demo on Steam but there is no Vulkan option apparent.  So I bought Doom last night in anticipation I can compare Vulkan performance. I will have a look next and see if Vulkan can be enabled on the Full Doom release version. 

I will post the type of Doom performance I see on this thread at a later date if you are interested.  

Thanks again. 

Bye.

Yeah, I know what it is meant to bring, but theory and reality can be very different or at least lag a long way behind. (Like pooled VRAM in mGPU support)

I hope it delivers.

Yes I agree with you totally. However Ashes seems to be delivering very well on DX12 and multiGPU from the benchmarks I have seen. So that is really positive. 

I hope Vulkan/DX12  delivers on pooled VRAM in mGPU too. I have a pair of unbalanced AMD cards (1 6GB primary and a 3GB secondary).  
Couldn't get another 6GB one by the time I decided to try Crossfire.

Anyway thanks for chatting. 

I will start asking about DX11/Crossfire on the AMD forum. You never know. A crossfire profile might turn up. 

Bye.
