1:1 Golden Ratio Is This It? What this means is that if you have your in-game acceleration set to 100. And your diagnol acceleration to 80% you are actually getting 80 in game acceleration but diagonally instead of horizontal and vertical which that's what "in-game acceleration" effects. So by going to the over watch profile that iogear provides I did some VERY BASIC math. I divded the X,Y sensitivity(they should be the same) by their "in game acceleration" setting. It looked something like this 75÷44~1.70. 1.70 is the magic number that you want to insert to find your perfect settings IMO. The formula for the 1:1 Ratio will only work if you have your X and Y sensitivity the same. I tested it once my self and I was pleased with the results, it looked like this: 60÷1.70~35. The formula is this: X/1.70=A. I hope this helps you guys out finding your perfect settings or helped me for sure. If you guys still don't understand I'll try to make a video this weekend on YouTube. Look up "widowmaker keymander"and you should find my channel Iogear admins if this incorrect old call me out. But At least explain this diagnol setting
