GPU: on discrete GPUs (CUDA), measured slower than `--gpu off` for Bend's slash boss draw (1.4x) and for portal-bend; with unified memory (Apple M-series), the GPU wins that draw. CPU (`--gpu off`): not measured. JS: no GPU, so no change. Confidence: medium, as it depends on the machine. Time the program with and without `--gpu off`. If the GPU wins, expect this finding."
