The Sims Legacy Collection - maxaspect launch option not working in EA App

It works perfectly on Steam.

This has been reported as early as of 3 years ago and hasn't been fixed yet.

EA App doesn't recognize characters like : + _ so you'll have to use a manual shortcut for those.
Oof - I knew I was right when I got TS1 on Steam!

Hi all,

This issue was resolved in today's patch:

• The game by default adopts the aspect ratio of the monitor it is run on. The aspect ratio can now be specified with the launch option “-maxaspect:<width>:<height>” (note that underbars ‘_’ can be used instead of colons). Examples: -maxaspect:16:9, -maxaspect_4_3 or bespoke ones like -maxaspect:16:10
• Note that the option will only set the aspect of height to width. It will only restrict the maximum width - it can not increase it
• In windowed mode, the window will run at the aspect ratio; at fullscreen black bars will fill the unused space of the monitor
• This will mostly be useful in situations where your monitor (virtual or real) is very wide, but you want the game to be a more traditional aspect ratio
• Note that there are limitations on how extreme a ratio this will accept

If you're still experiencing this issue, please create a new thread so we can continue to investigate.

Thank you!
