Hello, creator of instantOS here.
Multiple people have voiced their concerns about it being based on Manjaro, that’s why the next build will be based on Arch.
Manjaro also seems to have issues with graphics drivers when not using the official desktop environments. (some NVIDIA cards won’t even boot the ISO). The sluggishness is caused by the compositor (picom) which absolutely ruins performance when running without graphics drivers (you can also turn it off).
The good news is, that the graphics issues have already been solved on the Arch version, but it will take some time until it can be released.
The arch version will also feature a custom installer instead of Calamares which refuses to run with less than 1gb ram, although the distro can go lower than that (and has the internet issue which I have never run into)
The next build will also be uploaded to GitHub releases and OSDN which seem much faster. Maybe Sourceforge is throttling smaller projects, who knows…
And the ram usage on the live session is about twice as high as on an installed version, so in reality you would see about 130-150Mb, not 326Mb
@Head_on_a_Stick On my machines and VMs I didn’t discover any obvious bugs, would you mind describing the ones you were experiencing?
