I'd like if possible to ask a question to those who report that the nvidia
kms workaround "works".

In my experience, it makes indeed possible to work with fractional scaling,
but the performance is absolutely abysmal: I have tearing issues, drawing
issues and general extreme low performance, comparable to the Xorg driver.
Despite this being OK while waiting for proper support, I don't think this
can be a definitive solution.

So, is it just me doing something wrong and possibly needing to fix
something else or is this the same experience for everybody?

No polemic intent, just would like to assess what "it works" means in this
context.

Thank you very much
