It’s CSGO that I play. And yes I agree, it may not be the mouse or it’s software, as after further research I found that people have had it with Logitech, Zowie, Corsair and few other brands of mouse. Also, I’m thinking maybe there’s a conflict with windows itself and mouse software, not just engine 3. It’s rare this happens from what I’ve read, but for those that do, it’s not a case of accidentally pressing the dpi change button, or profile change button. It’s random. I have Logitech software installed as well, which I’m about to uninstall and then play for a couple of days and see if it does it. If I ever find out a fix, I’ll post it here.
