Like the title says, it seemingly randomly loses center. Can often perceive a bit of a jolt so it's instantaneous. I had thought it only happens when FFB stressed like when I apply a quick pull or turn hard enough to feel a bit of road resistance. But last time I was not turning hard, like a sweeping curve. Also have had it kick into its self cal routine turning itself from left lock to right lock. I get a screen display something like "controller input has changed" or the like. Thrustmaster has not replied yet to my emails regarding this problem. Has anyone else experienced this problem? Do you suppose its a Thrustmaster glitch or a rF2 glitch? EDIT: The following Launcher no-start problem is solved. http://isiforums.net/f/showthread.php/23225-Launcher-not-starting?p=345027&highlight=#post345027 Also, this seems weird but might be related, I started trying different rf2 in-game wheel profiles to see if any fixed the problem. Now, seemingly about the same time, I cannot get the launcher to open. I had this problem weeks ago but it seemed to fix itself after a couple of build upgrades. But now its back. Reinstalled the core and it helped some. Before reinstall it simply would NEVER start the launcher. Now it starts it like once. I must reboot to get it to start again.
