During the analysis of DX12, Microsoft opted to combine all of these objects into single and coherent Pipeline State Object where the developers can take one compiled pipeline state and use it compile the rest of the hardware states at one go.
In case of DX11, there were several objects which resulted in drivers ended up compiling at run time during draw calls resulting into CPU overhead and hence reducing performance. In DX12 all objects are in a single pipeline state object. The API aims to give developers console level efficiency and control on gaming PCs and mobile and the biggest draw is that no rendering functionality has been lost and anything that developers can do on DX11 can easily be done on DX12.Ī general overview of DX 12 capabilities. In terms of early access, over 400 developers from over 100 studios already have access to it. McMullen also revealed that DX12 capable hardware already comprises 50% of the current gaming PC market and that number is expected to reach 66% when the API launches this year. Microsoft have fully functional and performant drivers across the three hardware vendors i.e. During this year’s GDC, Microsoft’s Max McMullen went ahead and gave the audience an in-depth look at the new features and performance improvements that the new API brings in.įirst of all, the work on DirectX 12 has been largely completed with working drivers. There may be small tweaks due to the feedback that Microsoft will receive from developers but overall the current build is very close to the final version that they plan to ship later this year. It’s also supposed to reduce GPU overload and improve performance by 20% and it goes without saying that prospects are simply amazing.ĭuring last year’s GDC, Microsoft gave us a decent overview of what the next iteration of the API could do but they never really went inside the finer details.
Yes, it will reduce CPU overhead, which is something that will be a big win for players who play their games using dual GPU configuration. Much has been made out of what can be achieved using DirectX 12 but there is a lot we don’t know about the API.
