Final Fantasy XIV quality presets impact on performance
FF14 has few quality presets - from
standard laptop. For the most part with increasing quality setting you get bit more detailed shadows and physics on other characters. In terms of performance this can have a significant impact on FPS if you are GPU limited:
Gridania Aetheryte where a lot of players gathered is way more CPU limited than GPU and thus the difference is smaller. In open world the difference is pretty much double.
If you aren't hunting for a spectacular clip or screenshot it can be better to just lower the quality setting.
