FWIW disabling fullscreen optimization definitely helped with my overall FPS, I run on borderless windowed. I also did notice a big difference in overall "smoothness" if you will (never dropped below my Vsynced framerate). Sounds like yer havin frame pacing issues which does seem rather common in FFXIV. Giver a shot an see what happens? (Right click ffxiv_dx11.exe in the 'game' folder, you'll see that lil box under "Properties", "Compatibility". xD Sorry Dynratygus, forgive a smol kitteh for buttin in on the diagnostical processes >.> I'll go back to pesterin the local Lala populace as intended by the Twelve now...
