Installed TS, and when playing campaign, it runs super slow and jumpy, kind of like really bad lag. The menu screen often takes 5-10 seconds to open, the game slows even more when moving the mouse or scrolling around the map. I tried multiplayer, and got an update doing that, as was a suggested fix for RA, and it helped a little, but now it is back to being super slow.
Thanks for any suggestions!
