Latest Directx [exclusive]

The problem? If the GPU finished its work early, it sat idle, twiddling its thumbs while the slow CPU scrambled to feed it the next list of chores. Developers tried to fix this with "ExecuteIndirect," which let the GPU decide how many threads to launch. But that was like giving a line cook a calculator; they could count the onions, but they couldn't decide to make soup instead of salad.

The terror comes from memory. Because the GPU can now generate infinite work (a particle system that explodes into a million more particles), developers can no longer rely on static buffers. Microsoft solved this with —a safety net where excess work spills over into system memory without crashing the driver. latest directx
