Yes and Yes. AMD has released two drivers for Rage which pretty much fix the texture pop-in issues according to a hardocp.com front page release and nVidia released 1 but was better to start with. Even hardOCP's Mark said so:

The things people were complaining about, after driver releases from both companies respectively are now pretty much gone. Sadly, the bad taste will remain in people's mouths and the complaining about this game has become legendary enough to probably prevent some sales.
It seems pretty dramatic to start a letter writing/petition/campaign to ask for your money back because you had to wait 24-hours for ATI to release a driver and a later second revision before the game worked properly. Honestly, ATI/nVidia should probably have had this driver out BEFORE the games release if they were given a pre-release copy, etc for optimization.
My guess is they were too overly concerned with race for the best BF3 Beta Performance Drivers b/c they wanted their video cards to generate the most BF3 sales. So concerned, they gave Rage customers the shaft. I'd personally point my glaring eyes at my video card manufacturer slightly if a driver can make massive texture pop-ins be "significantly reduced"
Its not just the driver issues, its the lack of graphical options in the menu and the low rez poorly detailed textures. After 6 years or however long this took to develop, you would think they could have finished the high rez texture package for the pc version that carmack has talked about adding.
