Why? Is it hardware limitations or deficient software stack?
In any case, as nvidia is ignoring the gaming market, AMD and Intel both have a vacuum to fill, but I don't see them doing it.
Intel, especially, should have rushed out gaming cards as soon as nvidia shortages were predictable (2023, at least).
The problem I have is not that an old GPU can't be used for gaming (it can), it's that I am forced to upgrade from a perfectly working 660ti that once played far cry 3, 4 and 5 (and every other game I threw at it) because my kernel doesn't have support anymore (older drivers don't work on a newer kernel).
A new GPU with the power of a decade-old GPU but all the latest software support would be great. Right now, if I want to see certain web-pages (WebGL), I have to buy a new GPU, but there isn't any low-priced GPUs anymore.
