If the reduction is due to stack overflow protection, increase the stack size.
However, Windows and Linux drivers, as well as the NVIDIA CUDA architecture, have limits on how much work a single kernel execution can handle before it risks a event—where the OS thinks the GPU has frozen and restarts the driver. To prevent a crash, the rendering engine automatically caps the samples per thread to 32,768 . Why Rendering Might Be Slower If the reduction is due to stack overflow
Behind him, the quantum rendering array hummed like a hive of angry hornets. It was a beautiful machine—sixty-four entangled cores, each one capable of processing a billion realities per second. But the warning meant the machine was protecting itself. Slower. They didn’t have slower. Why Rendering Might Be Slower Behind him, the
“Override it,” he repeated, softer. “I need to see her clearly.” Slower
