Temp fix. thanks for pointing me in the right direction kingXray. I found that lowering my mouse's polling rate to 125 from 1000 significantly reduced the lag kick. it still reduces it, but it only drops about 10 fps, which is regained in surplus by disabling the 60 fps cap. though that makes my card run a little hotter than I like. Considering I don't think I'll be doing any sniping in FFXIV, its a playable fix. I don't know how lowering my mouse's refresh rate improves game performance, but I guess it has something to do with cross platform compatibility.
