Hi. For the last few weeks SL has run brilliantly. However, after logging on this morning SL has been a nightmare. I am currently running an average of 1-3fps...originally 20fps. Everything is so laggy! The only solution I have found is to lower my graphics from high right down to low! IE seems to be running fine so I dont think it's a network connection problem. I have also enabled SL to run by default with the Nvidia graphics as I am aware there are problems with integrated graphics and optimus. Any suggestions would be extremely appreciated!
