You could try 1280x720, which is exactly half the height and width, so you essentially have 4 pixel blocks that get rendered as 1 pixel. It might still not look super fantastic, but at least you'll have less intrusive interpolation.
In my experience and opinion, a small bit of scaling (say, 1600x900 to 1920x1080) looks worse than more scaling at a more regular interval, (1280x720 to 1920x1080) because there are less sharp pixels. With 720 -> 1080 You have 2 pixels spread across 3, so you only have 1 blurred pixel and 2 sharp ones. With 900 -> 1080 You have 5 pixels spread across 6, so you have 4 blurred pixels and 2 sharp ones.
It may seem counterintuitive, but it might be a good idea to lower the resolution MORE to get it to look a bit nicer. Plus, then you've got some extra GPU power which you can spend on higher settings like AA, parallax mapping and postprocessing.
