Yeah, precisely... A-A was one of the "forbidden" features, along with Vsync. Anisotropic filtering depended on the game - it was okay with Jedi Outcast, but caused considerable performance drops with others.

Also, smoke and transparency effects were a big problem... back in the day, when I played Quake 2 for the first time, transparent water and windows were a major framerate killer. In fact, the game's renderer has an option to improve performance by drastically reducing the quality of transparent surfaces - it's called "stipple alpha" and it produces this effect, example 1 / example 2 (notice how the water seems to be covered with some kind of "grid"). It was ugly, but it made the game run faster :P
