thanks for your feedback everyone. After tweaking with frustrating graphics settings ( I have a quad core system and a AMD/ATI 6870 1 gig) so should have no problem running this at all, I finally managed to get everything running how it should with only a tiny bit of lag. Being the uber geek I am, I have everything maxed out and I am used to playing games in insane resolutions.
After shouting "If I can run Deus Ex Human revolution maxed out then why can't I run you!" at my monitor things started to improve. I had the pleasure of encountering a mind numbingly racist guy from new york spouting a load of drivel about Mexicans who I chose to confront. That was interesting. I met one nice lady who helped me out with the basics and this morning I am going to tweek my avatar a bit.
I can see how really you have to leave your life behind to get the most of your time in second life. I was hoping to make a living selling floating hoverboards. I feel a little disillusioned this morning.
