I have an iMac (late 2006) and I can't get SL to work smoothly even on the lowest graphic settings. iMac (late 2006) 20" 2,16GHz Intel Core 2 Duo 3Gt RAM ATI Radeon X1600 128MB OS X Lion Every destination I've tried lags like hell, it takes about 1 minute to download and show all the shapes (even though my internet speed is about 800KB/s). The textures take a long time to download, and movement is very glithcy. It's impossible to use SL at the moment. I've tried to use SL with Bootcamp on XP, same problems there. Does this mean that my hardware is just incompatible with SL, or is there something I could do? Thanks in advance!
