Often times, the native resolution of the console isn't high enough to show the full detail of the textures. This is most strikingly apparent on Super Nintendo Mode 7 graphics: https://arstechnica.com/gaming/2019/04/hd-emulation-mod-makes-mode-7-snes-games-look-like-new/ https://arstechnica.com/gaming/2019/04/hd-emulation-mod-make... PlayStation 1 games suffer from a similar problem, and rendering at higher resolution in an emulator also often reveals a surprisingly high polygon count for eg. character models that look like badly-drawn sprites at native resolution. > I'm sure things like AA work better in the native renderer. Rendering at higher resolution is the highest-quality form of AA possible.
