The warning typically occurs in V-Ray or similar GPU-accelerated renderers when your scene is reaching the memory (VRAM) ceiling of your graphics card . Why This Happens
The warning is a common diagnostic message in V-Ray GPU (and occasionally other CUDA-based renderers like Octane). While it sounds alarming, it primarily indicates that your scene is pushing the limits of your GPU's Video RAM (VRAM) . What the Warning Means
: Having too many render elements (passes) during high-resolution renders increases memory utilization.
Sample Throttling Notification System Goal: To ensure system stability by preventing buffer overflows or GPU timeouts (TDR) when the user requests a sample count per thread that exceeds hardware limits, while providing transparent feedback that rendering performance may be impacted.
: The render will still complete, but it will be slower because the hardware has to process many smaller tasks instead of fewer, larger ones.
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.
