I am having performance issues starting with the the end of last season. I cannot get more than 58 frames with heavy dropping until I reinstall the game. At which point I get normal frames of 120-140 and then after a few sessions with the game it drops back down again until I reinstall. I was not having this issue until the last few weeks of Season of the witch. I don't think it is an issue with my PC as when I try running other games to check performance, they run fine. I have tried reinstalling drivers, changing the games installation location. Only reinstalling has been able to temporarily fix the issue. Any help would be appreciated.
