Did they change the camera again?
Have you upgraded to Windows 10 yet? If so this could be a factor. I have and have noticed longer map loads for some reason….
Apart from that even before I updated, Drytop and Silverwastes were always bad for me, must be all that sand and high places…
Since when did this business of being a hero become being a business?
It happens to me too, usually when the camera turns round certain areas in Sw, Fg, La and other spots. Even in Queensdale. My performance was fine 2 months ago with W10, so unless aW10 update or other driver is causing an issue, there may have been background changes ready for HoT causing slight issues.
