Its linux. Then either get in the config yourself and change the value or quit bitching.
Can’t always expect everyone to hand solve all of your problems for you, no matter how hard you complain
Edit to explain myself a bit, what I have an issue with is that this is a problem with a solution (not in the config), BUT that solution just isn’t easy enough for OP.
They want steam to test and maintain ANOTHER database of all their games for which ones most likely won’t lag in higher resolutions than the one they designed the entire system around.
This ain’t no linux elitism, its just that steam is focusing its efforts on making much more important things usable than simplifying this one specific workflow, which I 100% believe is justified (look how far proton has come solely thanks to steam)
