Second life - Utilising CMT slides and transcript

Just finished presenting in second life. This time the experience was not so good, my audio cut out unexpected during the presentation, so I ended up having to use chat to present the material. I was very glad that I'd gone to the effort of writing a script before the presentation, however, reading off the screen is not as effective as presenting the material.

Anyway, I found 'statistics' panel in the environment and looking at this indicated that I was down to <1 FPS, with massive lag. Interestingly, after the presentation and once everyone had left the presentation area, the FPS went up to 10-12. The SL program was still maxing out the CPU (as you might expect, I guess there's no reason to back off until the program hits the frame rate of the screen), but much more responsive - things actually happened when I clicked the on-screen controls.

So, I'm sorry for anyone who found the experience frustrating. I did too. And thank you to those people who turned up, and persevered, and particularly to the bunch of people who participated in the discussion at the end.

Anyway, for those who are interesting the slides and transcript for the presentation are available.
