yeh, because UI should be rendered after upscalings using native final resolution, then all could work
that would still leave 1080p players who are using fsr to have unreadable text that is part of ship or building textures via decals. The decals can't be rendered in native vs the base textures because i'd think it would look super out of place if part of the image is crisp ..and the rest is not.
For the UI that difference is fine..and not jarring. But seeing what should be a single object but with two drastically different qualities ..is about as noticeable as the LOD issues on the surface of planets.
1080p people should simply not be using FSR by default. the previous finity fx cas method @ 0.85 supersampling was an acceptable compromise for 1080p players. but FSR even at ultra quality is not doing as good of a job as that.
obviously the real problem is not which bandaid is best. But if fdev is able to actually fix / optimize their engine in a way that doesn't have a bunch of players who shouldn't be using these things from feeling like they have to.
