Please help confused about dx12

[Mahbub1]

i have heard that there are severel feature levels in dx 12.. and higher levels have more rendering facilities.. however i have one question .. dx 12 has a feature that it will use all cores eaually rather than putting pressure on one core and underutilizing others as in dx 11.. so my question is is this feature of using all cores equally present in all feature levels of dx 12??

It is. Actually, it will support all NVidia cards starting from the GTX400series. Not sure which models of AMD is supported other than the latest ones.

r9 270x has dx 12 support but i dont know which one.. i can live without all rendering blah blah i want only that feature wherein all cores are properly utilized.

This feature will be available for all feature levels of DX12. But this feature will really make the difference felt in the CPU multi core usage.

In sha ALLAH .. thats what i want... i want all six cores in my fx 6300 to be properly utilized.

Yes. I also have an FX 6300 and right now am using it with core parking disabled. But still it would not be as good as windows its self able to utilize all the cores properly. That would be great,.

whats core parking?? does it helpplz tell me about it.. i too will do it

Windows distributes tasks to the CPU Cores randomly rather than in a sequential manner. For a 6 Core or an 8 Core processor, this means half of its cores or at least 2 of them would be unused and they will be idle through out this period. This mechanism is called Core Parking. There are tools available all around the net for disabling Core parking for specific CPUs. You will get tones of such tweaks on the internet and notes on how to use them.

For AMD all GCN cards support the DX12 API. The API is where better multicore performance comes from, GPU pooling, and a bunch of other good features. API support is what's important for now, it will be a couple years before developers start to consider feature level stuff.

But I had heard feature level support for core utilization on some sites I had been going through for finding out more about DX12 features. They did mention about API support from GTX4xx series cards onward. AMD, most of the newer card they said. Not sure about the exact details.
