My case is a bit specific, I'm aware Ishiiruka supports this however I'm playing Metroid on the PrimeHack fork so can't switch to Ishiiruka. I don't know what the default downscaler is but it's bad enough that rendering at higher resolutions doesn't really change the amount of aliasing onscreen. Weirdly, increasing the internal resolution barely touches my GPU while using any of the AA modes spikes usage way up. Also I don't want to use AA anyway because Reshade can't access the depth buffer with AA on which I'm using for MXAO.
Beyond my case, is implementing better downscaling not a high priority for Dolphin? It seems like it would be since the multiples of native resolution almost never match up with your screen. So the vast majority of players are downscaling while playing anyway, right? Of course I agree a low quality but fast downscaler should be default to help out everyone using low end systems who don't know what settings are what but I'm surprised no toggle for something higher quality hasn't made its way into main yet.
