Alright, hate to post this, but one of the many things I've always loved about Spiderweb games is their low system requirements. I played every Exile game on a Mac LC, and never once noticed performance issues.
But Avernum 4 seems rather sluggish on my meek Mac 800 MHz G3. Compared to Blades of Avernum and Geneforge it's really sluggish - I'm sure compared to the latest bloatware game from my local Apple store, though.
Anyone else notice this? Am I still in the dark ages running an 800 MHz G3? The mouse tracks across the screen very slowly, though movement is a little better.
Anyway ... can't complain. Price is always right on a Spiderweb game and I really enjoy playing them. If nothing else, this is another reason to pick up a new Intel Mac early next year!
