I've been playing on second life with this graphic card. Initially, I experienced a lot of lagging. But once I've learned to lower the graphic settings in SL, there were less lagging. Also, I've learned to stay away from places that have too many scripted environments and stick to the beaches and less busier sims.
But my question is: my graphic card, intel cantiga, is it stronger than the Intel 945 chipset that SL recommended as the minimum requirement?
