It seems since the latest patch that this bug has reared its ugly head again. http://feedback.arma3.com/view.php?id=8002#c44818
I am currently running the latest driver from saitek which is 7.0.34.109 and am having the same issues as reported in this previous bug report. i have also tried all the formentioned remedies to try and rectify this problem but to no avail it stll seems the response time is halfed compared to the keyboard. i Know i did not have this issue about a couple of months ago when i last plugged in the joystick but i do now after the latest armas 3 update.
