hmm, I have experienced some general lagginess/choppiness in the past. Some solutions previously were to delete the "DiskCacheArena" file in the swtor folder (it gets re-created when you launch swtor) or deleting the "Bitraider" folder (it gets re-created when you launch swtor as well, but also initiates a file verification check). It has been a long time since I've had to do either of those, but if you previously played swtor and are a returning player, those solutions may help if you haven't tried them already. Alternatively, though a Much slower process, would be to uninstall swtor then reinstall from a fresh launcher from swtor.com (assuming you have not done that already either). This solution should ensure that all of the files are most up to date and that the launcher is most up to date, from a fresh download, but it will take a while depending on your connection speed.
