We can do it, and see the result across driver versions and later updates. So the chance this gets fixed is minimal. Also, even if it somehow manages to pass Tier-1 support and reach actual Nvidia developers, who knows if enough DX9 games are affected for them to care enough. I doubt there are other options, Nvidia is too big to still listen to individuals making bug reports. I can test it out, but I don't think patching a frequently updating driver is a good idea.
