There's a large FPS drop if more ppl are gathering at the same place like for example 100+ players at Limsa, or more ppl doing S-Ranks, Eureka, Diadem. This has been a while since I started playing back in 20017. I hope they fix this. I have 90 FPS in-game with Standard settings (60+ FPS on High settings)...but when ppl started to gather that's when my FPS drops to 39 on Standard settings and less than 30 while on High graphics settings.
