Today I opened a flight and the throttle on my X52 would work in the plane I’d selected so I tried another and also that didn’t work… tried rebooting the PC as well as the sim multiple times. The weird thing is the axis setup in the sim and windows controller setup showed the throttle moving and there were not any binding issues either. So last resort was to reset the sim in the taskbar, I didn’t really want to do this as MSFS is glitchy ATM anyway and didn’t want to make things worse. Well long story short It sorted the throttle control issues out ! so If you have any glitches like this give it a try, the only thing that I can see that got reset within the sim was the graphics settings. Also the sim felt smoother ? maybe a placebo effect IDK.
I have the same problem in all my flight simulators with my x52 (MSFS, DCS, and War Thunder) The throttle just jumps from idle to mid to full as if there is a bunch of dead zones. I have checked the USB game controller thing and it says there is not. It also said my throttle is working just fine. Weirdest of all my throttle used to work fine, but then after I installed some drivers from it from Logitek it started having this problem.
