Lag in game....

[Fuzball]

Goto start menu-> Microsoft DirectX SDK -> DirectX Utilities (64 bit) -> PIX for Windows (64-bit)

Then file-> new experiment -> hit 'More Options' -> 'Target Program' tab -> set program path to ffxiboot in your SE folder -> set the 'skip processes' to 2

Then 'Triggers/Actions' tab -> select 'Unspecified Action' from the tree list -> change the action type to 'start collecting GPU events' then click 'Start Experiment'

If all is well, you'll see a FPS counter at the top left when ffxiv starts... Login, run around a bit, then quit.
The stats will load after ffxiv exits and you'll be able to see stats for every frame, draw times, gpu load, etc... If you want to investigate further you can set up a wait trigger and collect draw data, which will let you see exactly what ffxiv is rendering each sub frame and how much it's bogging your system down.

When you have this problem, do the frames stand perfectly still, or does it just keep you from moving/doing actions?
