Can someone please confirm what the oldest nvidia GPUs that are still being optimised in recent releases? I had a quick trawl through the release notes and couldn’t find any details like “performance improvements in game X for xyz GPU series”. It’s one thing to say that such-and-such GPU support is included in the latest driver, it’s another thing entirely that any improvements have actually been made for that GPU.
I personally would be surprised if a GPU series that’s two generations out of date was still getting actual driver optimisation work. I can’t remember seeing any performance improvements in new drivers for ~4 year old GPUs ever.
