If you hit control+alt+delete and go to the task manager, and select FFXIV as if you were going to kill the process, hit end task, but do /NOT/ actually confirm that you are going to kill the task (Just to bring up the window) this seems to clear some memory on the card that was falling behind, and lag INSTANTLY goes away for me after this.

I have also noticed it to go away immediately after opening the task manager sometimes, without fake-killing the process.

I am curious if this works for other people, so if it does for you please let me know It has been working great for me, and is really fast to do.
memory is flushed by the host compositor if you alt tab in pure full screen mode.
