I experience the same behaviour; Vault with only a few files
But my file is really long (it is saved Webpage through Markdown extension for webrowsers); I am reading it, and really often it does wait a few seconds until it render next part when I scroll it
My specs
- Intel Xeon E3-1535M v5 (top processor, but came out 5years old) ; 64 GB of RAM (this is my workstation); NVIDIA Quatro M2000 2GB, there are loaded drivers for nvidia
- Linux OS, Obsidian as flatpak
