Problem with slow loading of files in Revit 2019

[JosephGQRWJ]

Greetings...we have a number of machines that are all similar specs hardware wise,. but loading drawings on a couple is much faster than on others- the only difference we find: 1) one of the fast machines is Windows 7, all others are Win 10 PRO, 2) faster Win 10Pro machine has older video drivers (nVidia M620), 3) faster machines have older Revit 2019- version 19.1.0.112 20180806_1515 (X654) 2019.1. Any ideas on why these machines with older software/drivers can load drawings twice as fast as other machines, given otherwise similar specs (hardware and Windows versions/update level)??? Thanks

Check the free space on the hard drive for the computers that are slower - perhaps they are getting full, which will slow them down.

check if all hardrives are the same (ssd or conventional rotary disc)

SSD perform better and provide faster response 

video cards will vary regardless of OS if they are not compatible with Autodesk applications you may notice a lag in performance

Is there /are you using a central model. If so do you open the central model by itself or a local file when this delay appears?
