I changed the graphics options, only after someone said it fixed their problem, I chaged all my settings from low to medium, my computer isn't high end so it doesn't cope well with the high graphics options, I don't recall changing any of my settings in my AMD Catalyst console, recently the issue happened when I did the Emerald Knights quest in Emerald Graves, I will attach my dxdiag shortly.
I have used a few mods but these have been in place since the start of the game, and I have not changed them, I don't even remember their names, as I have installed them and deleted the downloaded files.
I am kind of a little irritated that I have to now reinstall everything, I thought that it would have asked if I wanted to do a change, or at least give me the chance to cancel the uninstall, no worries, cannot undo it, I'll just have to download reisntall all the mods again, as well as the patches and DLCs.
