Running R 4.1.0 in the RStudio IDE on windows w/16 GB RAM & I noticed that the memory usage report in RStudio doesn't match the task manager. EG, with a new project & nothing loaded, the memory usage report says I've got 49% of memory in use, but only 125 MB used by R/Rstudio. The task scheduler says RStudio is using 700 MB of memory, but matches the 49% total.

I haven't run into issues, but does anyone know if something is going wrong here?/if not anyone mind explaining what's going on to me?
Thanks!
