The AMD Driver Thread

But that's only the case with current graphic API's. With Mantle/DX12/Vulkan there are no more driver optimizations. It will be up to the developers to do all the optimizations work that today is done by the driver.

Thats going to be a steep learning curve for some dev's i'm afriad :(

Couldnt mantle still get vendor optimizations like BF4 ??, How will be dx12 be different than that?

GTA5 PC version Rockstar have pushed the PC hardware to get the best performance out of that! reason it runs so good across the board is because they put the time and effort into doing just that.

Except they haven't. If GTA 5 would be able to get everything out of the hardware two 980 in SLI wouldn't be sitting at 80% load or lower in game.

Real effort to get the best possible performance out of the game would mean support for Mantle/DX12. I can understand why they might not have gone with Mantle, but if the game doesn't get support added for DX 12 they obviously don't care about getting the best performance a PC can offer.

I imagine that most of the optimizations will be in the engine and not actually game specific. The drivers don't have any optimizations. Could vendors help out engine/game devs with optimizations? Sure. They helped the Thief guys by adding Mantle to Unreal Engine 3. But that was early on when Mantle was still in development and there was no proper documentation and still some issues with the API.

Does AMD help the PS4/XBONE game devs optimize console games? Nope. You are going to have the same thing with DX12 and Vulkan.

Thanks for explaining that :)
 
I think both (devs and vendors) are responsible.
The developers have to do some work, but they can get help from AMD/Nvidia to support features like multi-GPU and AMD/Nvidia should be pushing this support so the games work well on their hardware.

If DX12/Vulkan puts more control in the hands of the developers assistance from the vendors may be even more important.

Features like multi-GPU and such is probably why we see engines being re-used so much so that the wheel doesn't have to be constantly re-invented.
The downside to this approach is that we're stuck with something like the Source 1 engine for a decade.

People were complaining of poor Crossfire performance in the game Dying Light. The developer, Techland, have released a game patch which has corrected these performance issues. The patch should automatically download on Steam.

Just tried this (been busy with GTA V as of late!). Even with the gameworks stuff on I'm getting 100fps with minimums of 80 with 2x HD7850 in the old town. The anti aliasing method the game uses still has a weird shimmering effect in crossfire, so I've turned that off, but an amazing performance boost from that update!
