I use a 1070ti and T500 without any issues with EndeavourOS, but I do recall having to install a bunch of packages to make the nvenc encoder detected.
I do not recall the packages… but I think there are some va-api packages specific to nvidia that aren’t installed by default; I’m not super confident on that tho.

Their flag is extra wide

Cool!
The fit is very unforgiving. It might be hard to use with plastics that warp or with poorly adjusted printers… Or if the PCB is cut a bit larger.
I had trouble scaling the part and had to be… Creative. Thats why the thumb portion’s shape is strange.
Glad to see it works for you!
