I noticed some choppy scrolling after upgrading from 1.16 - any idea what settings influence this?
Should be mostly vsync. Try moving your retroarch.cfg somewhere else temporarily to see if default settings help.

         It’s fixed 
No idea what I was doing but I just copied my old config- works now

         I figured out that it was the “Sync to Exact Content Framerate” setting - this should be ON for my display, although I haven’t even enabled it on the monitor - I guess it’s enabled by the graphics card? Who knows. It’s smooth as butter with it enabled
