I am using Firestorm viewer and i have a Macbook Air. The performance of my computer is not really suitable for SecondLife but despite this i manage to access and work in the West Hillside community without too much lag. Here are my tips: All manipulations are to be done in the "Preferences" menu of your viewer - In the "graphics" tab: Reduce your graphic quality (I use medium quality and i use the maximum quality only to take pictures) and Reduce your draw distance (I reduce to 32 and increase slightly when i need) - In the "network and files" tab: Clear your cache regularly (browser cache, inventory cache and your viewer's cache folder) ⚠ Remember to restart your computer (if it has been on for too long it can get slow and a simple restart will solve the problem) ⚠ If you are accessing the sim for the first time or if you access the region again after clearing your cache, objects and textures may take a few minutes to load. Be patient :) If despite all this you still have too much lag, we advise you to visit our available skyboxes. Since lag is a problem especially in busy places like in residential communities, you won't have this problem in our skyboxes since they are in the sky and fairly spaced from each other.
