Why is it that in Rainbow Six the resolution is allowed to be 1920X1080 and the 4:3 aspect ratio is enabled in the game settings, but in CSGO I have to adjust the resolution if I want to get it to 4:3?

You can do this in CSGO to, what exactly do you mean?

In most cases it doesn't change the calculation, but you should always enter your native resolution in the resolution field, and select the forced aspect ratio in the aspect ratio field.

24分鐘前,DPI Wizard說:

你可以在CSGO中做到这一点，你到底是什么意思？

在大多数情况下，它不会改变计算，但您应该始终在分辨率字段中输入您的原始分辨率，并在纵横比字段中选择强制纵横比。

Thanks for your answer, my English may not be very good, I would like to know why I can use 1920X1080 resolution and 4:3 aspect ratio in Rainbow Six Siege? But in CSGO to use 4:3 you have to set the game resolution to say 1280X960. is Rainbow Six Siege automatically changing the game resolution but not showing it?

Ok, I see what you mean now. There is no reason why, it's just different ways of implementing this.
