Procedural textures on multi-core ,[object Object],[object Object]

Procedural textures are valuable for modern games ,[object Object],[object Object],[object Object],[object Object]

Introducing Substance ,[object Object],[object Object],[object Object],[object Object]

What is Substance ? ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Less FPS ? ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

No, a stable and high FPS. ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Performance issue: streaming in games ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

The architecture was designed with these issues in mind: ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

The theoretical benefit was calculated ,[object Object],[object Object],[object Object],[object Object]

This is the approach taken to address the issue: ,[object Object],[object Object],[object Object]

Here’s the code that was developed to make this possible: ,[object Object],[object Object],[object Object],[object Object],[object Object]

Threading strategies ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Threading sub graphs (1/11) by nodes (high level) ‏

Threading sub graphs (2/11) by nodes , caching

Threading sub graphs (3/11) by nodes

Threading sub graphs (4/11) by strips (low level) ‏

Threading sub graphs (5/11) remove from cache

Threading sub graphs (6/11) by strips

Threading sub graphs (11/11) update cache , and finished

Expect more streaming bandwidth ,[object Object],[object Object],[object Object]

Here’s how close we got to the theoretical best performance: ,[object Object],[object Object],[object Object],[object Object]

Here’s the new performance profile: ,[object Object],[object Object],[object Object],[object Object],[object Object]

This is future-proofed ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Coherent procedural normal map

Complex procedural environment map

This scene is made entirely of procedural textures

Future sources of bandwidth ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Here’s how you can best take advantage of procedural textures ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
