More important to Rainbow Six Siege, but when the aspect ratio is set to 4:3, horizontal feels faster, and vertical feels slower as a result. I was curious about the potential of multiplying the vertical sensitivity to match aspect ratio, such as scaling the horizontal sensitivity to 133% on 4:3.
When I use it in game, it makes the game feel more natural at 4:3, and I feel that I can aim for where the pixel is, especially on diagonal targets.
I'm not sure if there is any topic related to this and I was wondering if you would have an insight on this.
