I am running the latest versions of both R and RStudio on a Windows 10 desktop. I work primarily using R projects if that is relevant. Though I don't appreciate any real improvement in speed if I try just running a simple script.
Yes, I work in a university and am on a computer there. I made sure not to have any of my projects in a network drive because I have read that can complicate things.
It might be something to do with where packages are installed. I have had that issue with work computers where even though R is installed locally, the packages somehow get installed on the network drive.
