It loads before the stock NVIDIA driver, needs no patched driver or VBIOS flash, and persists across driver updates. Benchmarks show the RTX 4090 doubling peak BF16 throughput from 165 to 329 TFLOPS, with real workloads gaining 25-55% on LLM prefill, 25-50% on fine-tuning, and 30-55% on image generation. Outputs stay bit-identical. Blackwell (RTX 50) is not supported, and gaming or FP32 CUDA workloads see no change. ## Full article daily.dev links to this article rather than hosting it.
