Thank you for rubbing it in as it prompted me to retry the solution.
You are absolutely right. I shouldnt have installed TM drivers (But I was just following what their manuals and Website instructed.) I again uninstalled ALL the TM softwares i.e TPR driver, TM calibration Tool and T.A.R.G.E.T software ( I had earlier tried with uninstalling of TPR driver only). unplugged TPR Pedal. Restarted PC and then connected TPR Pedals and then ran MSFS. It worked well this time though infrequently still showing some minor erratic response/behaviour. Some of the time Inputs are somewhat more sensitive for Rudder control But for Toe brakes these are less sensitive, sometime (not frequently though) while taxiing or run for take-off the plane shows tendency to move to one side more (usually towards left but sometimes to the right) but its very minor as compared to initial drastic movements.
So MSFS is playable with TPR Pedals now but I have to keep in mind that sometimes it may show a sudden tendency to turn to one side. I love the feel of using TPR Rudders but compromise on some time ground movement to one side on taxiing / taking off.
I checked to see if any issue with MSFS and unplugged TPR and re-plugged my old Saitek Pedals which did not show any issue of sometime unexplained movement to one side on taxiing / taking off. I again plugged TPR pedals and observed Virtual pedal in the MSFS Sim cockpit while plane is on ground/ stationary. I observed that Pedal movements are smoother but when TPR toe brakes are pressed the virtual pedals in the sim cockpit show slight movement backwards at times at the begining of toebrake press or towards end of pressing the toebrake.
However, with slight annoying issues surfacing some of the times only (sometime tendency to move slight to one side on taxiing and Toe brakes sometimes not giving same response as usually given and Rudder becoming more sensitive, though less frequently, while flying in air) TPR Rudder Pedals are USUALLYY working fine. So using them as a compromise till full solution for 100% of the times smooth functioning is achieved.
Maybe I shold have just plugged and played as you suggested and not installed TM calibration software/driver in the first place.
Waiting for 100% smoother performance ALL THE TIME from my TPR pedals. Any suggestions for resolving these remaining minor and infrequent issues?
