I made a tweak guide that works for some (see my signature) but two bugs remain:
1. When I start a new game RAGE loads an amalgam of blue bands. I've to restart again and see the lengthy intro before it loads properly.
2. The Texture Cache setting won't stick; reverts to "Small" everytime I load the game
These are minor annoyances; they're not game breaking but here's hoping the devs will look into this.
