game runs slower on small screens

Unity Engine
1

hi there
i’m making a 2d game , i have this canvas (in the picture) , the player runs and jump with the speed I want in the editor , but when I build it to the windows platform : the player runs and jumps very slowly (it’s not a problem in my graphic card , my friend also tried it and its the samething)
How can I fix it ?
thanks

UI is not intended for such purposes… however, if you want to use it anyways you will need to make sure that the proportions are correct. In other words: you probably want to control the anchored positions of your character rather than some positions which are affected by the canvas scaler.

PS: you should be able to reproduce it in unity by changing the resolution of the game window.

Show your code for player movement. Most likely you’re not correctly scaling the movement for different framerates.
