How to change mouse sensitivity when changing resolution?

Question

Mouse

I played the game with full hd, I had 900 dpi and 6/11 in windows. The game does not have sense settings, this is not a shooter.
I changed the ratio in the game to 4:3 resolution on a 1400 x 1050 mouse and in the video card settings I set the image to stretch along the edges of the monitor so that there were no black bars. In Windows, I changed the resolution to the same one and set it back to fullhd and tried different dpi (including different ones in X and Y), but I just can’t get my old mouse feeling back.
I couldn't find a calculator specifically for my case. There are only calculators for the senses between games and the Desktop with cs go, but there the sense in the game is set up completely differently.

Are there any formulas so that I can recalculate it all? In the same place, stretched edges and sensa in Windows should probably be taken into account.

Answer 1

When changing the resolution on the same aspect ratio, this will not happen. But the loss of sensitivity of the sensor due to the change in aspect ratio is normal if the new resolution is stretched to fit your screen format. As I understand it, this happens due to an increase / decrease in the number of pixels on the screen, while trying to stretch them to the previous scale. the fix is ​​quite simple, thanks to the formula that changes your sense: Y(sensa before) x P(ratio before) % ​​K(new ratio) = new sense.
example: 0.69 x (16/9% 4/3)= 0.69 x 1.33333= 0.92
Please note that the aspect ratio in the formula is taken as a fraction. In your case, the number obtained by dividing the aspect ratio is the approximate number by which you need to increase/decrease the number of mouse DPI
