Re: the sims 4 controls not working in fullscreen mode

@bolivari  64-bit is not a resolution, it refers to the length of the memory addresses an OS or application uses.

Please run a dxdiag and attach it to a post.

Please also load Sims 4, open the graphics settings, and list the resolution you see right at the top, for example 1920x1080.
