On the consoles the game (EP1 at least) runs natively on 1920x1080. So I believe removing the limit used on the PC port isn't so difficult.
Episode 1:
PC Version:
PSN/XLBA Version:
I can't confirm if Episode II runs on 1080p on XLBA but at least EP1 is fixable.
Shame really.
Episode 2:
Here it's how it runs on PC and PSN:
Here it's how it COULD look (8x AA + Morphological Filter + Edge Detect + Perfect Resize 7)
I'm posting this here because this guy was able to make it run on 1050p natively. He used a debugger to do it but doesn't know how to make a more flexible solution.
I'd be happy with 1080p at least :((
