Re: SMALL UI?
@xthrones1994 Sorry for the late reply; I'm not sure whether I missed this post or the spam filter ate it and spat it out later.
The UI is dependent on the in-game resolution, not the graphics card or its settings (at least as far as I've ever seen). The higher the resolution, the smaller the UI will be. Yours does look pretty small for 1920x1080 though.
One thing that might help (or it might not) is changing the system and user DPI to 96 (100%). Sims 3 doesn't always respond to settings like that, and it's at least worth testing.
