Magpie VS AviSynthAiUpscale

You can try to launch the game with a lower resolution and upscale it using FSR with Magpie or Lossless Scaling (my favourite). You'll have to add a custom resolution and then upscale.

If anyone does this, you will find that the base resolution is really small, and putting it in fullscreen makes the Deepl translation go away, to solve this you can use a free upscaler called Magpie, it even upscales the subtitle box along with the game client!

You can use Magpie, which is meant for upscaling VNs but also has the side effect of making VNs basically borderless fullscreen.

This version of Magpie, specifically. The Anime4K scaling usually works like a charm, but with Dohna Dohna it doesn't seem to do anything, nor do the other options seem to have any noticeable effect.

1) go here: https://github.com/Alexkral/AviSynthAiUpscale/releases/tag/1.2.0 and download the zip file.

They're just taking the Blu-ray master, downscaling it back to SD resolution, piping that video into Topaz Labs' VEAI and using a Gaia model, and then re-encoding that. Probably not before throwing a bunch of grain on top, because VEAI isn't that good. For every bit of piece that looks nice, you're also met with a bunch of shimmer or other anomalies, removing any sort of consistent look from the image. The models are always being updated as well, so you might even be able to make a "better" remaster with a newer VEAI version (though I would recommend an FSRCNNX based upscaler, as it gives off a more natural appearance)
