No it hasn't, Nvidia usability in Linux now is the same as it was 10-15 years ago, and that's sort of the problem. What do you think has improved since then? I remember ~18 years ago getting Nvidia to work with the proprietary drivers on my Mint was just a couple of clicks away and I could play oblivion and many other games that ran on Wine (and the very few natives we had) just fine. The majority of the Nvidia issues are self-inflicted, always have been, the problem is that because you have to use the proprietary drivers it's very easy to shoot yourself in the foot, and inexperienced people tend to do it very often, so my guess is that 10-15 years ago is when you started using Linux, and broke stuff with the Nvidia driver, nowadays you don't break that stuff and you think the driver has changed, when what has changed is you.
