Stella, Retronic USB adapter and Atari 2600 Paddles

[TripHammer]

I'm running Stella V4.6.6 and I just bought a Retronic USB adapter and configured it for the Atari 2600 Paddles. I cleaned the pots on them to eliminate jitter. I tested them in windows (10) in the joystick control panel and they respond fine. It could be a little faster but it tracks left and right as quick as I can move it with no noticeable lag. When I try and use them in Stella, only a small range of the paddles cause movement on screen and it lags making it unplayable. Lowering the digital sensitivity doesn't work as it's then slow and lags. It's just not responsive enough to be playable on the few games I tried (Breakout, Circus Atari, and especially Kaboom). Has anyone else tried this combination and got it to work and what setting do you use?

 

Thanks all.
