There is a noticeable improvement when mapping R3 to the same keyboard key I have L1 mapped to, not great but noticeable. Looking forward to the ST being updated, so that L1 is used for ADS, not R3. Can't really leave it that way for now unfortunately as having both L1 and R3 in use at the same time prevents me from shoulder switching while aiming which I do constantly. Any additional action is cancelled out if L1 and R3 are in use at the same time. I also can't zoom in while aiming of course without also assigning a secondary key to R3 and using that instead just when I want to zoom in. Wanted to also let you know that I checked the SetPoint settings I burned to my G500 again. Somehow by accident I had my DPI settings set individually for the X and Y axis. Not sure how that happened, because I'm sure I checked the option to use the same DPI setting for both. So anyway, I had the X axis set to 5700 DPI and the Y axis set to 1800 DPI. This explains the difference in sensitivity I was seeing in-game when moving my aim horizontally versus vertically.
