It's good to see Alex go into more technical depth than usual, I think it's important sometimes. It's one thing to tell people they'll get some performance by lowering a particular setting, it's even better if you can tell them why so they'll understand what the change is doing beyond just "turning it down".
I set up my Avatar: Frontiers of Pandora settings the way he suggested, and it works like a champ. And I honestly didn't even notice there wasn't a setting for textures in that game, I just went down the list setting things.. lol. But I went and looked at it again just now, and yeah... that setting just isn't there. I get why devs don't tend to do that ("Auto-Detect Settings" rarely works as well as we'd like it to), but this makes me appreciate the times that they do. I mean, Avatar looks fine, more than fine, I think we can all agree on that.
