So I don't have a slow system. Brand new AMD 3950X 16core 64GB ram 1080ti. A great system for what I need.
What ive noticed is with Garmin Express running or even installed it seems to causing alot of stuttering and slowdowns on my system for some reason. I looked into it and now have uninstalled it for the stuttering to disappear. This should not happen with a tiny bit a software designed to update my Fenix 6X Pro. There is seriously something wrong with your software if its doing this to a system like mine.
I will not have this installed whilst this continues. Ive been through the mill with bad software and dont need this from a new watch and someone as supposedly sought after as Garmin
