1) My PC build can run FFXIV at 1080p and 60fps:
- Everywhere
2) Other settings (visual effects, drivers...):
- Maximum
5) The PC build is:
- CPU - i7 4790
- GPU - GTX 980ti
- RAM - 8GB 2666Mhz - Dual Channel
This is while Playing @ 4K Resolution, so I imagine 1080p would be much higher.
----------------------------------------------------
Because FFXIV is primarily CPU Bound when pushing for a constant 60FPS this is the build that you could work with.
i7 (Quad with Hyperthreading - Ivybridge or better)
8 GB of Ram - FFXIV does prefer higher ram speeds so 2133Mhz or better
GPU - GTX 1060(maybe GTX 1050ti?) or RX 480 (RX 470?)
You can pair an i7 with a much cheaper GPU and achieve the contant 60 FPS at 1080p.
You can also use an i5 IvyBridge or newer for a near constant 60FPS but there will be dips in highly populated areas due to the lack of Hyperthreading.
