Lag around multiple players

[Stonewallx39]

I’m playing on a older computer (toshiba laptop) and the game runs pretty well most of the time. However I get really intolerable lag when I’m with groups of larger than 20 characters. This has made pretty much any real raiding impossible.


I’m wondering if anyone more technically savvy than myself could recommend upgrades I could make for my computer or settings changes that might help.
