2 GAME DEVS & ASYNC SHADERS DAN BAKER, PARTNER, OXIDE GAMES I ve heard of developers getting +30% GPU performance by using Async [Shading]. [ ]it could end up being pretty disruptive in a year or so as these GCN built and optimized engines start coming to the PC. 2 DIRECTX 12 & AMD RADEON GRAPHICS AUGUST, 2015 APPROVED FOR ALL AUDIENCES

3 ASYNC SHADERS WHAT ARE THEY? HIGHER FPS Breaks complex graphics workloads into many parallel tasks Idle GPU resources do work instead of waiting their turn Parallel workloads = jobs finish faster = more performance Increasing granularity of the multi threading improves performance GREAT FOR VR More parallelism = lower latency = more responsive VR IMAGE QUALITY GPU PERFORMANCE Opens up GPU resources for free graphical effects that don t compromise performance 3 DIRECTX 12 & AMD RADEON GRAPHICS AUGUST, 2015 APPROVED FOR ALL AUDIENCES

6 GAME DEVS ON ASYNC SHADERS With async shaders, we can fill parts of the GPU that [would] otherwise be forced to sit idle. It's one of those features we wish we had on every GPU. DAN BAKER, PARTNER, OXIDE GAMES [Async shading] can be used to add more game features without affecting performance or to increase efficiency by performing existing work in parallel with rendering. JOHN KLOETZLI, PRINCIPAL GFX DEV, FIRAXIS GAMES On The Tomorrow Children, the flexibility offered by moving the bulk of our rendering work to compute was just too great not to take advantage of. [ ] [Async shading] really made a lot of things possible that would have been incredibly difficult otherwise. JAYMIN KESSLER, SENIOR PROGRAMMER, Q GAMES 6 DIRECTX 12 & AMD RADEON GRAPHICS AUGUST, 2015 APPROVED FOR ALL AUDIENCES

7 PRESS ON ASYNC SHADING It turns out that NVIDIA's Maxwell architecture has an Achilles' heel after all, which tilts the scales in favor of competing AMD Graphics CoreNext architecture better prepared for DirectX 12. TechPowerUP Oxide s developer also revealed that NVIDIA s Maxwell does not support natively Async Compute, and that NVIDIA asked Oxide to disable it for its graphics cards. DSOGaming [ ]AMDcardshavebeenbuilttotake advantage of DirectX 12 s features, mainly thanks to Async Compute which should become more prevalent in the next couple of years.

8 WHAT ABOUT NVIDIA MAXWELL? Curiously, [NVIDIA s] driver reported [async shading] was functional but attempting to use it was an unmitigated disaster. Ashes of the Singularity Development Team AFAIK, Maxwell doesn t support Async Compute, at least not natively. We disabled it at the request of Nvidia, as it was much slower to try to use it then to not. 8 DIRECTX 12 & AMD RADEON GRAPHICS AUGUST, 2015 APPROVED FOR ALL AUDIENCES games dev replies ashes singularity controversy/
