Question Can't change screen size for games

[Beeef]

so whenever i try to open a game i cant make the size smaller, its stuck at 1920 x 1080. this is annoying because i usually need to run games in a smaller window for them to run smoothly

Which game can't you change it ?
Most games let you change and I've never known a problem. Also you need it in "window" if you can.
