ANY HELP with the continuing graphics card drought has to be good news. Mining cryptocurrencies using GPUs hasn’t helped. It can be highly profitable, and well-funded mining operations tend to hog the supplies of the best chips. Nvidia has decided to help by building a limiter into the driver of its new GeForce RTX 3060 card, which halves the hash rate for Etherium mining. Apparently this is the currency most suited to mining with its GPUs. It’s a start, although why not limit mining across all cards, and all currencies? Nvidia has said that it currently has no plans to extend the idea. How secure the driver block proves remains to be seen.
