>That doesn't even work on certain transparencies
you say "doesn't even", but clearly it's an edge case that may well be a single flag flip away.
the point is that, in principle, you can do any algorithm on the CPU. you're not babysitting the API, and the API is not babysitting you.
the only real 'limit' for filtering is 8-bit palette. I don't actually know if there's any other reason for it than memory - and if that's the case you could drop the texture resolution by half (feasible for Unreal), go full 24-bit, and still remain 25% in the green.
