Here's a few tweaks (You'll need Nvidia Inspector)
Basically, just match the settings in the profile I print screened to your own Dishonored profile in Nvidia Inspector (Make sure to apply changes once done).

If you don't have Nvidia inspector, but have an nvidia card, here's where you can get it (Highly recommended for Nvidia users)http://downloads.guru3d.com/NVIDIA-Inspector-1.94-download-2612.html
Once you've set up everything properly, things in game should look noticeably better in terms of anisotropy and AA
Anyways, hope this helps someone out.
enjoy and post feedback if this worked for you (It should if you have an Nvidia Card)
EDIT: If anyone needs help using Nvidia inspector, feel free to ask :)
EDIT 2: Another thing to note is that you'll need a geforce 500 series Nvidia card (at very least least) to handle the increased graphic settings ( 4x multisampling and 4x Sparse Grid supersampling).
Those of you with older Nvidia cards can try 2x multisampling and 2x Sparse Grid supersampling instead.
EDIT 3: (See Edit 4) Avoid FXAA injector (A programs that while useful in many games, like Skyrim, doesn't seem to work here), in my case it prevented Dishonored from launching. (See edit 4)
EDIT 4: OK so Apparently FXAA injectors (like sweetfx) will work if correctly configured. There's some pretty nifty graphic enhancements available with it, also, it's important to note that FXAA is much less resource intensive than the AA alternatives I propose. Thanks to Aeneas2020 for pointing this out.
Here's a link to the sweetfx utility: http://skyrim.nexusmods.com/mods/23364
EDIT 5: Screenshot 1:
- Using only in game AA
- fps locked at 60 using V-sync
- Everything in game looks very jagged and washed outhttp://s1062.photobucket.com/albums/t498/irondm11/?action=view¤t=2012-10-14_00001.jpg
- Using Nvidia inspector for 2x Multisampling and 2x Sparse Grid
- FPS locked at 60 using V-sync
- Already a huge improvement over game defaults
- Still a bit of aliasing visible on the fence down on the waterhttp://s1062.photobucket.com/albums/t498/irondm11/?action=view¤t=2012-10-14_000022x.jpg
- Using Nvidia inspector for 4x Multisampling and 4x Sparse Grid
- FPS Drops to 50s in big areas and also when using blink (Phase ability)
- For me, this is the sweetspot. It's eliminated about 80% of aliasing in game and textures look noticeably better. Still, some of you will prefer to avoid the fps drops and stick with 2xhttp://s1062.photobucket.com/albums/t498/irondm11/?action=view¤t=2012-10-14_000034x.jpg
- Using Nvidia inspector for 8x Multisampling and 8x Sparse Grid
- Frame Rate Drops to 30s and sometimes even lower
- Gpu heats up something fierce. Nothing dangerous though
- This setting eliminate pretty much all aliasing, but at great performance cost. I wouldn't recommend using this setting with a 500 series card.http://s1062.photobucket.com/albums/t498/irondm11/?action=view¤t=2012-10-14_000048x.jpg
Note: You'll probably need to resize the images on screen to notice the differences. I hate that Steam's screenshot utility doesn't seem to take 1920x1080 screenshots.
