I'm having this issue where the game runs at 6 fps while I am in game, but when I tab out with the Windows key it runs faster (currently 30fps while tabbed out). It was fine earlier when I first started the game and then it crashed after a cut scene and this issue has arrived. I had the same problem with PSO2 and the only way I fixed it was to edit my user file to force true full screen as Virtual and Windowed Mode both had the problem.
Is there a fix for this? My system is top tier and my internet is gigabit. It is NOT related to how many people are playing since this happens from the moment the SEGA logo comes in.
