DX12 - Multi-Threading Shadow Map Rendering Performance Boost, Can Be Applied to Existing Engines

At this year’s GDC, Kuba Cupisz and Kasper Engelstoft, graphics programmers at Unity Technologies, talked about Unity 5 and DX12. Now we all know that DX12 is going to be big, however we don’t know how developers will take advantage of it. Well, according to Unity’s programmers, DX12 can be used for multi-threading shadow map rendering as it can significantly boost performance and can be applied in all existing engines.

"DX12 can be used for multi-threading shadow map rendering as it can significantly boost performance and can be applied in all existing engines."

This is great news for developers, as they would have to do a full rewrite of their engine. They can get games out on the API that much sooner.

I do think that engines written around the API will perform much better though.

"I do think that engines written around the API will perform much better though."

Agreed.

I can see the next Gears game using multi-threading shadow map rendering a lot. Its going to be one of the best looking game at E3 because Gear's storyline has gone back to its Dark roots.

Ehh not quite following you, the graphics will be better because the story line will be darker? It's always been a dark game colour palette wise. With bright red blood!

Shadow maps can be used to hide unwanted polygons(or graphics) in a scene to get back some(or not waste) processing power on a DX12 based hardware. Shadow maps can also be used to hide empty space.

This makes sense for a game that is dark.

Holy crap! Just by multithreading the shadow maps they dropped the render time by about 45%? That's insane...

Better lighting, no more pop-ins and better frame rate.

It's definitely an exciting time to be a gamer!

Hoping to get 2-3 years out of my r9 295x2 before making the push for a 4k worthy machine. Hoping freesync makes its way to tvs ... I game exclusively from my recliner, but that might change if pc monitors keep making drastic gains on tvs ...
