I know what your talking about. Those problems started with me around the time the released the Tequatl updates and took of culling. Those changes made the game almost completely unplayable for me on my old laptop unless I stayed in low-pop areas which just isn’t fun because it meant I had to miss out on all the big events and all the loot the big bosses drop.
It finally culminated in me quitting the game completely for quite a while until finally my old laptop bit the dust and I got myself a gaming laptop, and now I can play it just fine. But before all that my old laptop could play the game just fine, sure I had a little lag, but it was playable. I shouldn’t have had to go out and get an expensive game laptop just to have the ability to play this game and enjoy it, it’s just ridiculous.
