What long list of reasons? LHR has absolutely zero impact on games. If anything, its presence was helping gamers because miners were at least somewhat put off buying LHR GPUs, making them more available to gamers.
By that metric you never did, and LHR doesn't change anything here. It's just yet another out of million optimizations baked into the drivers already, except this one is on BIOS level.
Ever heard of Code 43? Or the dozens of other software locks nvidia uses to be able to sell you essentially the same silicon at 4 wildly different price points? You never owned it and you won't now.
They were trying to make their products less attractive to people who were buying out their traditional customers. You aren't even going to own a GPU if they were all hoarded by "crypto" miners.
It helps them in one dimension and harms them in another. I think the ridiculous scarcity and price mechanics of graphics cards right now is a way worse issue than drivers, and we can advocate to have that fixed. Doesn't matter if they fix the drivers while cards are still 2k+ because I won't be using them anyway.
