I don't play videogames and know very little about crypto mining, but isn't the mining being done on specialised hardware these days and not GPUs? Are GPUs still being wasted on crypto nonsense?
Given the continuing high price of video cards these days, I'm going to say yes, many people are still leveraging GPUs for mining.
EDIT: Maybe not as much as previously, but still enough to have a noticeable impact on the market.
