Machine Learning Summit: Real-Time Neural Texture Upsampling in 'God of War: Ragnarök'

Xuanyi Zhou  (Programmer, Sony Santa Monica Studio)

Pass Type: All Access Pass, Summits Pass

Topic: Programming

Format: Lecture

Vault Recording: TBD

Audience Level: All

This talk gives a detailed breakdown of the run-time neural texture upsampling system in God of War: Ragnarök—including how the networks are designed to directly output BC compressed image blocks, how the process is optimized to take full advantage of PlayStation 5's GPU hardware, how all the components evolved during the prototyping and development process, and the limitations of the specific approach adopted in the system.

Takeaway

Attendees learn about the inner workings of the neural image upsampling system in God of War: Ragnarök, as well as the challenges faced while creating the system. Additionally, the talk offers insights on GPU optimization, both in general and in the context of neural network evaluation.

Intended Audience

This is for programmers interested in machine learning and GPU optimization. Basic knowledge about machine learning and console GPU architecture is recommended.
