How to get unfiltered upscaled native resolution?

[TheDax]

With 1x render resolution, 3x window size, nearest filtering, and no postprocessing shaders, here's what it looks like for me (click it to see the full size):



So it's definitely a settings issue, unless differing GPUs are causing weird bilinear filtering issues, or something.

Edit: Are you sure it's something that would have to be added, Henrik? That shot I posted looks relatively crisp.

The best results would probably be 2 or 3x resolution with nearest, though, as suggested above.
