well i have been on SL since 2008 and i never had a rezzing or loading problem... But since this SSA has been introduced to SL.. i see grey ppl except my avatar... and it takes a lot of time to load up... SL worked smooth for me before the SSA.... So theres no problem with the System. But still fyi i have the core i3, 4gb ram, with the Nvidia geforce cuda 310M... and i have done a clean install almost 10-20 times by now... but its still slow.. and i used to seeing gray ppl now... most of my friends had the same problem... Some have left playing SL cos it never got solved.... So pls do look after this
