I dont know how Second Life actually works with AMD if they're not even familiar with this place, its a virtual world ran by Linden Lab, been around since 2003
So you go to
https://secondlife.com/downloads make an account and download the client (its free with a basic account), just choose any pre made avatar and go in-world.. the first step is some orientation island thing that you can skip, just click on the search button and search for a club like Warehouse21 or Peak Lounge. Teleport to the location and look at other avatar skins and see if they notice flickering shadows over their faces or any part of the avatar skin that is on show.. just keep away from Adult Sims, you might see something you didnt want to
