The idea that the AMD drivers that id Software were testing the game with were fine is just silly. The release date was well known by both parties and the issues with the public drivers were well known, so surely there should have been some coordination? It makes absolutely no sense for this situation, as both RAGE and AMD are tarnished by it. And the Crossfire drivers are still a week away, when most games ship with them.
Anyway, the technical issues have actually done id a favour, as otherwise they'd be talking about the terrible design decisions:
1) Invisible walls everywhere
2) Can't pick up weapons from dead people - they fade away
3) Dozens of inviting doors but maybe 1% can actually be opened
4) Accepting a mission skips character dialogue, breaking immersion
5) Terrible auto-save system
6) In game text pop-ups telling you stuff, even telling you to save regularly
7) Enemies using the same animations, to the point where they die on top of each other in the same pose
8) Horrible vehicle physics (Borderlands was much better)
More annoying is that just months ago Carmack was interviewed and stated that they should have put more of an emphasis on the PC version and that they'd be changing their design process to accommodate that. Now that all the initial sales have died down he reveals the truth. Surprise, surprise.
