My desktop has 8gb of ram. But yeah, I have faith that general performance issues will be ironed out. I noticed a big improvement between the betas and now in that area already. Thank you for bringing my ram to my attention though, because I hadn't checked that in a long time and may look into upgrading for some other things too.
I'm currently running the latest version (10.2.4 build 1949 public) on Windows 10. While notes load swiftly in the note frame, whenever I try to open a note in a new window, it takes 4-8 seconds to load that note.
