One of the most significant changes came in mid-2021, when Nvidia released "Lite Hash Rate" (LHR) versions of its RTX 3000-series GPUs that halved their performance when mining Ethereum or similar coins but didn't affect their gaming performance.
Cryptocurrency miners have tried to circumvent the LHR limitations in a bunch of ways since then, including by using non-LHR drivers that Nvidia leaked (oops!)
and flashing the BIOSes from 3090-series cards onto 3080-series cards to bump up the hash-rate limit.
And earlier this week, a hacker by the name of Sergey released an "Nvidia RTX LHR v2 Unlocker" that promised to remove the hash-rate limits on most Nvidia cards using a combination of BIOS updates and specially modified drivers.
Surprising no one, the sketchy drivers with the too-good-to-be-true performance promises turned out to be full of viruses.
Other times, as with this well-known AMD driver package for Macs running Boot Camp, it's the best way to get consistent driver updates with the latest fixes and performance improvements.
If mysterious drivers from a previously unknown third party promise a silver-bullet fix for a problem that the entire cryptocurrency mining community has not been able to figure out, you probably shouldn't install them. »
