AMD Radeon GFX & DirectX 12
- Thread starter LtMatt
- Start date
12_0 is nothing more than DX11 but allowing cards to make use of DX12 low level optimisations. All the goodies are in 12_1 or higher. AMD are being disingenuous here with this.

We will find out soon enough when we have games running.. Until then this discussion is pointless.

Confuses as to why amd are advertising any of it as a amd only thing. U can do all this with nvidia and sli or nvidia card with onboard GPUs like the Intel ones.
Its a nightmare to write drivers for games.
Developers had to deal with Dx11 and lazy development from microsoft. sli/crossfire will see benefit with dx12.
You bought a 4 core or 8 core cpu and it just sits there idle most of the time playing games when it could be utlized a lot more than one single core.
so now we will find games have a bonus effect due to dx12 that we previously have seen in several generations of cards before but now unleashed a whole new level of power thanks to the new API of dx12.
I found this interesting and one reason AMD will have a good line up for windows 10 and gaming the coming years.
Yea, pretty sure people here have got far more than 10M on 980's.
Once again AMD are being disingenuous by using a test that requires the full resources of the system to do nothing more than draw simple polygons. FM themselves have asked that it not be used as a benchmark. The only DX12 gamengine test we have seen shows NV having a huge performance advantage.

Such as?
The only thing we know for sure is 3DMark's API test, wich shows AMD with the advantage.

meh, split frame rendering has been around since the dawn of multi-gpu gaming, it didn't work well because the workload in different parts of the screen can be vastly different. Nothing has changed, it is just a fundamental limitation. Sure, with DX12 developers probably have better control rather than relying on the drivers to split the screen but that doesn't resolve the situation.
And the shared memory is nice and all except it only has the advantage of preventing duplication of a resource that will only be used by one of the GPUs, which basically never happens. texture and geometry etc are going to be needed on both GPUs because it will be far too slow exchanging resources between GPUs.
This works much better for compute applications.

And FM say that it cannot be used as a benchmark so there is no advantage visible.

Also, layte, someone being a developer doesn't mean they are not talking BS, I should know!
You're looking at it with rose tinted glasses, a lot of developers aren't going to bother fixing things that a small proportion of enthusiasts complain about, once they've got their money from the masses most of whom are running Intel integrated what does it matter to them if a few AMD users are having a particularly bad experience in some extreme cases? Is the BF4/Mantle memory leak fixed yet? how long did that take? it obviously wasn't a priority for the developer and those whose interest it is in (AMD) won't be able to fix it themselves via drivers? if this happens there's just going to even more complaining from AMD about how all of the developers aren't doing their job properly. NVidia will probably still be doing their thing with developers before release so it shouldn't affect them much either way.

If you look past the AMD logos on the pictured graphics cards, none of the text actually claims any of this as an AMD only thing. It's simply AMD pushing the benefits of DX12 as a whole rather than pushing AMD (and adding pictures of their own GPUs, which makes sense if they've made the presentation).
Because they have no products to sell, just PR spin and hot air.

It seems AMD spend more time making slides and presentations than actually writing drivers.

They wrote Mantle, which large parts of DX12 is based on, and the overwhelming bulk of Vulkan (plus some spicy new stuff) is based on.
Both should mean driver optimisation of titles is far less necessary. CF / SLI profiles should certainly be a thing of the past. Except all bets are off in NV GameBrakes titles ...
