it was really simple, I should have thought of it first save myself the time.
I log on this morning on Tatooine ( lvl 27 shadow ) to a FPS of 6-10 sometimes 15, when yesterday it was in the 40ies, not great but playable.
so after messing with setting from the game to the video card, I figured I'd just do a full reinstall and well the game runs better than it did before.
sometime is the simplest of things.
