SL is MUCH more graphics intensive than WoW...MUCH more. You will NOT get the same visual quality with your iMac. You can check your FramesPerSecond by opening EDIT / STATISTICS BAR. Stand Perfectly still somewhere quiet in SL, and watch. I get 5 FPS on my Mac Mini in a typical shopping mall, and 18 FPS on a quiet beach.
------------------------------------------------
The settings below are really dumbed down...but if SL still runs slowly, report back, and we'll check for System Issues.
Assuming your DSL and System are okay, lets
Start with the SECONDLIFE VIEWER Preferences.
Open the Preferences (EDIT / Preferences...) or CMD+P
You'll see tabs down the left. Set the following on the tab shown:
