I love the game don't but its looking like I will need to take a break for a month until this gets fixed, every time i look south on Indar my frames drop to about 3 and my gpu usage goes from 40% to 100%. I have a 580 and did not have this issue before the patch.
Where were you standing? Does this happen in everywhere? Try to do some diagnostics to find out what's causing it. For example, is there a difference between being on Indar or Esamir? Is standing on the north edge of Indar looking south the same as being on the south edge and looking north?
