I installed the latest 4.2 Thrustmaster drivers for the T500RS yesterday. I immediately noticed rF2 crawls when you select the Controller settings tab. It takes several seconds for rF2 to register any event, i.e. pressing a pedal or assigning a command. After noticing this, I tried build 660 and the same issue occurs. Something is not working well between the newest drivers and rF2. Also on 789, a few seconds after getting on track rF2 freezes, the sound cycles as the image freezes, I am forced to force quit since the rF2 does not respond. This could be due to plug-in issues.
