What is the "native" resolution of Blasphemous?

[Toni]

The game is based on 2D pixel sprites, so what is the "native" resolution? I dont want that any scaling destroys the "pixel perfect" representation.

Thank you!

It's weird how a lot of the resolutions are marked as having Pixel Perfect scaling mode for me while the rest don't:

720x480, 720x576, 800x600, 1024x768, 1152x864, 1360x768, 1366x768, 1440x900, 1600x900, 1600x1024, 1680x1050.

Is it possible that the unlisted resolutions like 1280x720 and 1920x1080 are already pixel perfect or something?

Native resolution is 640x360, so any multiples of that like 1080p are pixel perfect.
