its because I do not want to keep changing config everytime I want to change sensitivity a little bit(image it mid match too) that I changed one time by a decimal , so I just use the in-game slider , like the majority of the r6 comunity did while ago and it makes easier to compare to people that have the normal one ( since its a change in decimal of the original , 3 becomes 30 etc...).
But ok , if it is that hard to open for us to input ours its ok. I`m just using it like that for years and it get in my nervs how much difficult/annoying it is for me this way.
