The game, in its currently state of development, suffers off poor programming/optimization. The only thing you really can do at the moment is to encourage it with stronger hardware. While being heavily GPU bound it is also heavily CPU limited, believe it or not, my i7-2500k bottlenecked my GTX580 in this game up until i overclocked the CPU to 4.5Ghz, especially in citys. Right now i can maintain a steady 60 FPS in citys, outdoor, near camps, no matter how many active PC/NPC are around, its running perfect.
My detailed system specs as reference:
Intel i7-2600k at 4,5Ghz
Nvidia GTX580 at stock
DDR3-1600 (8GB)
Samsung MLC-64GB SSD
(a dedicated SSD drive for the installation does real wonders for the load stuttering in citys)
Windows 7 x64 HP
Game settings:
Display Mode: Full Screen
Windows Size: 1920x1200
Multisampling: 4xMSAA
General Drawing Quality: 8 (Standard)
Background Drawing Quality: 5 (High)
Shadow Detail: Highest
Texture Detail: High
Texture Filtering: Highest
Ambient Occlusion is still a no-go (I wonder why, its not that demanding in other games).
Within the Nvidia control panel it is recommended to force vsync and activate triple buffering for ffxivgame.exe. Helps big time with the extreme tearing the game also suffers and improves performance a little bit in fullscreen mode.
Obviously, the hardware requirements are in no relation to what you actually get to see on the screen in terms of graphics, Square Enix needs to work on the engine, it doesn't help at all if the game is limited to PC enthusiasts who got 3k€ machines, they really need to make it run better on mainstream PC's. Releasing a next generation game that is expected to run for 5-10 years, may it be multi-platform or not, with not even DX10/11 support and native x64 binaries is a shame also.
With best regards
