Unity Founder: DX12 Alone Doesn’t Give A Significant Performance Boost

During this year'southward GDC, Unity demonstrated the advantages of DX12 along with the Unity Engine. Unity'due south Graphics Engineer, Kasper Engelstoft spoke during the demonstration about shadow maps rendering in Unity. When using multiple threads, the frame time to render shadow maps was 23 ms but when developers switched over to DX12 the frame fourth dimension was reduced to 13 ms. Kasper explained however that for this to happen they had to revise their threading schedules.

Developers wanting to include DX12 back up in their game engines would need to make elevation level changes to their framework structure.

GamingBolt caught up with Unity CEO David Helgason larn more than details on how the new API volition work.

"The API lonely doesn't requite a significant performance boost, it simply allows scaling on multiple cores, and that'southward what we demonstrated at GDC," Helgason said to GamingBolt. Even so he believes that once their threading and scheduling strategies are in place, rendering in Unity volition be much faster. The developer won't require to alter a thing in frameworks resulting into native DX12 support. "Once our code is set Unity rendering will but be faster – almost users probably won't have to modify a thing in their projects to receive the operation comeback, because all we will do is scale their rendering on to multiple CPU cores."

Helgason also talked about Enlighten, a lighting middleware from Geomerics.

"Ane of the peachy things nearly Unity five is the inclusion of Enlighten from Geomerics. It'southward known for in-game existent-time GI, simply it also provides is a vastly improved lighting workflow for artists. Faster workflow ways faster iteration which means better looking levels and content in general. Part of this is due to an iterative mode which removes the need for explicitly baking the scene. This basically ways the scene will precompute and bake in the background and the Editor will automatically track changes made to the scene and execute the tasks needed to prepare up the lighting. Many of these lighting iteration tasks will exist nearly instantaneous.
