Just finished installing Legends, and it seems as though the UI is far less responsive than it was in ROTS. When I click on a button, like characters, it takes a couple seconds to come up, and it seems to come up in pieces, with an outline and white boxes before being filled in. I suppose this is kinda petty to quibble about, but it is quite distracting, and immersion breaking. I can take screenshots of this process if anyone would like. I am using the latest beta, but I had seen this before I installed the patch. Right from the main menu I get this behavior. All my drivers are up to date, win7 64, 4 gB ram, 500 mB video card, 2.4 gHz quadcore processor and nothing extra running. After monitoring my system resources I am nearly certain the game is only using one of my cores, or at least almost entirely one. I think getting this game to use all four of my cores would solve most of my complaints.
Is this normal behavior? I am nearly certain it was much better in ROTS, but I have not played that for awhile so I may be misremembering. Also, nebula clouds are still causing massive lag. Disabling them in systems really cuts down on the lag when zooming into systems, but when zooming into gas clouds it is painful.
I am not just griping (I don't think so anyway), but the main thing I was looking forward in this expansion was a performance boost, but it almost seems to be running worse. I love the game design, the ideas, the depth, but I have a really, really hard time looking past lag.
