New optional --efficient mode for Pearl. It draws noticeably less power for nearly the same hashrate - on RTX 40 (Ada) cards, about 10-13% lower power for about 3% lower hashrate. The result is better energy efficiency (more hashrate per watt).
For miners optimizing electricity cost or running power-limited rigs. The default mode is unchanged and still targets maximum hashrate.
Optimized for RTX 40 (Ada). On other GPUs the flag safely falls back to the normal maximum-hashrate mode - no error, no change in behavior.
