We have reached a point where CPUs aren't getting much faster; they are just getting more cores. Work Graphs finally admit that the GPU is the star of the show. By letting the GPU manage itself, Microsoft has effectively removed the traffic cop from the intersection.
With , the GPU launches a "Node." That node processes the work. If it needs more work (a second bounce, a third bounce, a particle effect that spawns more particles), it spawns a child node right there on the silicon. latest directx
Imagine a ray-traced reflection. In the old model, the GPU shoots a ray. If that ray hits a mirror surface, the GPU has to stop, bounce the data back to the CPU, wait for the CPU to say "yes, shoot another ray," and then restart. That round trip costs milliseconds—an eternity in gaming. We have reached a point where CPUs aren't
No CPU involvement. No round trip. The GPU becomes recursive. I spoke with a graphics engineer at a major AAA studio (who requested anonymity due to NDA constraints) about the new SDK. His response was blunt: "It’s terrifying, but necessary." With , the GPU launches a "Node
