I have been collaborative and constructive in the past, provided all the technical information 7 months ago, and still no progress. Hoping the next patch to fix this. I'm tired of this issue, it makes the game look like it is still in an alpha stage. I believe this is a top priority issue for SE development team, before adding new content, even before correcting in-game bugs. Many people experiencing this issue discredit the entire game based on this. It kills the will to play. The game has to be playable with specs equal or above requirements, period. I proceed with a bug report in the most formal way to get a formal follow-up and reply on this from the development team. Regards, and good luck fixing this issue.
