Here's how I got mine working, after the freezing fest of late that you just described. Number 3 is really important, as is the custom config. As I got the game to stop freezing up with job_numThreads 0, and got the game smooth with the config.
1. Game was patched via Steam to new version
2. Installed 11.10 preview 2 drivers
3. Added Rage launch options in Steam with: +set com_skipIntroVideo 1 +jobs_numThreads 0
4. Created a new "rageconfig.cfg" in steamapps\common\rage\base
5. Put the following into the rageconfig.cfg
6. Save, close, and run Rage.
Thanks for the help flibby. The 11.9 and 11.10 preview 2 drivers were no good for me for some reason. I uninstalled them and downloaded cat 11.6, and now the game works perfect! I got the console working by typing com_allowconsole 1 into the default.cfg. Interestingly, it doesn't use my tilde key. Instead, I discovered the console comes down when I press the ' key, that's the key with both ' and @ on it. Only thing left, and it's not even important now as I can load saved games, is that I can't get the skip intro video to work. I also typed com_skipIntroVideo 1 into the default.cfg directly under the console command, but it still doesn't skip any intro videos.
