Mouse wheel zoom is not smooth. It waits until I am done rolling the mousewheel before it inputs the zoom It's not a graphics card issue as I have a beefy workstation and the shift+mouse3 zoom is working fine (although it doesn't zoom to my pointer.) I've tried everything on this forum. It relates to parts and assemblies. It happens with 1 line or 1,000 lines. I have reset the program, reinstalled,  I've messed with a lot of the settings. What am I missing here? 2015 and 2016 worked fine.
