Love it but have generally the same criticisms as you. Luckily there are mods that help both of these issues:
this one helps slightly with performance: https://www.nexusmods.com/oblivionremastered/mods/35
and this one with difficulty: https://www.nexusmods.com/oblivionremastered/mods/58
Also playing on steam deck I can’t tell if aim assist is helping at all. Can be difficult to look at each gold to pick it up with a controller.
you’ll have to reset the parental controls (mkey): https://wiki.hacks.guide/wiki/3DS:Remove_Parental_Controls
then you’ll be able to erase system data. Don’t bother with the “remove pin” option it is broken
