    Tonight I learned that anti-aliasing is pretty much the only thing that affects framerate in Source-engine games, or at least Portal anyway. Switching from 4X MSAA to none made the framerate near perfect, even with nearly all other settings maxed, on my basic-spec laptop. Can't wait to try this with other games. !vgp

      @ecmc Yeah, AA is _really_ computationally expensive, and a lot of lower-end graphics processors (especially those in laptops) don't have any hardware support for it, so it can't be offloaded to there. (Not that lots of the other stuff isn't computationally expensive too, but most of that has wide enough hardware support that your CPU doesn't have to do it.)
