Looks like the Low Framerate Compensation works with my LG 29UM67 tuned to 30-75Hz. I can do 20FPS and there is no tearing.
The animation at 20fps is not fluid because object move quite a distance between each frame, so you really want to be closer to 30 fps anyways. But hey! No tearing even below 30 fps is a nice bonus.
I used this guys driver:

Nice find! I wonder if this would work on the 34" LG ultrawides. I'm in the market for one of those plus a 480 for Christmas.And it can be tuned:
