Same here. Even 1620p gives me shimmering on edges. It's weird, how bad it is.
Hopefully someone smarter than I can find a fix.

T2X gives me a much cleaner image, pretty sure it's the better one.

Honestly game looks kinda bad at 75 FOV. Maybe because dafult FOV is very low (45)? I am playing with 60 value right now.

You can turn off Chromatic Aberration?? Take note other devs

Man, I hate the CA, motion blur and film grain. Good job you can turn it off. Props to the devs. Not everyone includes those options.
Only issue with it is the aliasing which is pretty awful. It's everywhere and none of the in-game options help that much. Can't really downsample on a 660 either because it drops to around the 45ish mark which is too low.
Oh, and it seems there's a bit of mouse smoothing going on? It definitely feels off. Can't see any options for it though.
Anyone know if I can inject some AA with the control panel or something else entirely? Preferably something that isn't too power hungry.
Anyway, apart from that it runs flawlessly at 1080/60. Nice engine those guys have.
I'm using an i7 2600k oc to 3.5ghz, 8gb ram and a GTX 660.

It's so weird to look at the game with it's nice character models, great environments and great light effects and then around all this there is flickering like in a over 10 year old PS2 game. Okay maybe this is over the top, but it looks so strange with everything else looking fantastic.
That's because it's vertical FOV and not horizontal FOV as in most games.
Look here for further information: http://pcgamingwiki.com/wiki/Glossary:Field_of_view_(FOV)#Understanding_FOV
Also there is a calculator to get your right FOV. If you have a normal 16:9 , 1080p monitor you would normally use a horizontal FOV of 90, which is a vertical FOV of 59. So in AI you would go best with the FOV of 60.
EDIT: Sry, for double post.

Nice, thanks
I typed your specs into the calculator again and it gives me these results:
New hFOV = 106.26
New vFOV = 73.74
http://www.wsgf.org/fovcalc.php
EDIT: You used this calculator with a desired FOV of 90? http://www.rjdown.co.uk/projects/bfbc2/fovcalculator.php, Should be higher with your monitor
That calculator is way better than this one:
http://www.rjdown.co.uk/projects/bfbc2/fovcalculator.php
Yes, a little bit further down the site on pcgamingwiki there is the second calculator =) The first one is to find out which vFOV you would need if you know which hFOV you normally want to use. The second one shows the best setting for your resolution.
Absolute max everything at 1440p runs 90fps+
4k drops to about 50fps. I set it to fullscreen windowed to fix the vsync which doesn't seem to be working.
780ti sc
4770K
Lots of chromatic aberration on some objects, looks a bit fuzzy.
Also looks awesome and really enjoying it so far. Just watched the movie yesterday for the first time.

That is odd... either they mislabeled the T1x (and it is just 1x) or something isnt right with their implementation. Everything we have read about T1x points at is being superior in everyway to T2x...
Oh well, driver downsampling it is.

I'd be interested to know this as I have the same card and the game looks great.

So downsampling doesn't fix the bad Aliasing? That sucks.
Dictator93

Really? But it's x2
haha well that is just my dyslexia
Plus everything in the settings for some reason is flipped-flopped. Some are better quality going right, some better going left.
Also thanks for the help porcupine.
That confused me for a bit too.

T2x has obvious ghosting problems while T1x doesn't. T2x handles some of the shimmering better though.
Went as far as 2160p, and while it's much better than 1080p, some of the shimmering was still there. Other than that, the graphics are great.
The game itself seems to be right up my alley, too. I don't think I'd ever give it a 6/10. Not a chance.

i7 and a 780, looks like 4k at 60fps could be doable with a little tinkering. Not bad at all, after how badly Shadow of Mordor ran (crash to desktop all the time) it'll be nice to play something a little more stable.

Maybe the jaggies are part of the art style and they were placed there on purpose. Did you ever think of that? It's their artistic vision man.
Could be true, I'm feeling even more horror when I look at those things than when I'm meeting the alien.

i5-2500k, 770 4GB - as expected 60fps on ultra. But the aliasing really destroys the atmosphere, is this "shader aliasing"? Has anybody tried injecting smaa or found sgssaa bits for nvidia cards? Whatever, game seems to be great.

Definitely this and nothing to do with shader aliasing being notoriously difficult to eliminate.
Yep, its shader aliasing. Its the same reason why Star Citizen is currently so jaggy, because it has very advanced shading and nothing to fight its aliasing yet.
Ryse handled it by special filter in g-buffer and specially prepared shaders and textures and yet we need something better in future.

So I downsampled it to 4k and I'm still getting those beautiful jaggies:
Shader aliasing.
EDIT:
This.
For whatever reason the game will now let me load saves without crashing on loading screen. It makes the game amusingly less stressful knowing that not only I can save but also load it and start where I left off.
Graphically speaking the game is convincing if not terribly impressive. One particular detail caught my eye : the metal shader on the revolver, it looks great.
Too bad that the majority of the materials are not anything special, fucking cross-gen development.

OK, this is a really dumb question (but hey worth a shot):
The game crashes for me once I try to load up the game (it boots ok, but once I try to play it is when it shits the bed).
I admit this is almost certainly down to having a GPU that doesn't meet the minimum requirements (Radeon HD 6770M 512MB vram). Is this the likely cause of the problem?
I was willing to play the game in shitty circumstances until I can upgrade, I just thought it'd still run =/

yeah, I did, pretty much everything. I guess it's just not to be.
I'll get to playing it in about 3 months time then =/

To remove intro movies (20th century fox, Creative Assembly, AMD):
Go to \DATA\UI\MOVIES in the installation folder.
2. Delete or rename AMD_IDENT.USM, FOX_IDENT.USM, and CA_IDENT.USM.

Thanks, you should put all the useful stuff in the OP.
