Hey there, so I did a clean install of Windows on 17/10, pretty recently cause I had insane FPS drops, after reinstalling every single software and FF, I ran an alliance raid and frames were pretty good and stable, very close to 60 or 60. (I play on 1080p@60Hz, i5-6400+1060 3GB) but as I kept playing and playing, eventually I had issues in P3S which is 8 man instead. I tried setting battle effects to limited and I still get unplayable framerates like say +- 40. What could be causing this issue? Is there a way to troubleshoot it ?

Thanks in advance!
