DPI scaling of the regular steam GUI can also be wonky if you have different monitors. For example, I mainly use steam on my lower DPI secondary monitor, but it wanted to scale based on my 4k main one. Could be fixed with an override though.
Anecdote from my first job (software engineering): New manager wants to know what our team does and how our process and software works. Like, he really really wants to know it!
Okay, I book a timeslot and prepare some slides and an example; we have a meeting. I go over the high level stuff, getting more and more specific. (Each person on our team was responsible for end-to-end developing bootloaders for embedded HW.) When I got to the SW update process and what bit patterns the memory needs to have and how the packets of data are transmitted, he called off the meeting and I’ve never seen him since.
I guess, he didn’t want to know THAT much after all.
For all the flak they (rightfully!) get, a 1st party open source nvidia driver is in the works.
Altough it’s only the userspace part and it’s not compliant (yet?) to be upstreamed into the kernel. It is still something.
There is a scaling factor for the GUI (by default it checks your monitor’s DPI).
