View Full Version : Poor graphic quality of the shorelines

I have asked this before, but can't find the post anymore.
I think most of you have this "problem". When you turn up the Anti Aliasing the plane looks a lot better, but the shorelines do not.
I've got a x1950pro with the catalyst 6.9(tried 7.1: no diff) drivers for the x1950pro.
I run the game at 1280*1024 and it really looks great with high fps(mostly 75).
AA*6 with temporal AA enebled
no AF(will sharpen the land textures making it look worse)
Mipmap detail to quality
Vertical refresh on
Adaptive AA to quality

Before the x1950 i had a 6800le. I know that setting AA to 8 will solve the problem. But the ATI card can not do that and fps will be to low anyway. Is the anyone with a sollution?
The funny thing is, the AA is doign what it's supposed to do when you bank the plane. The shore lines look mutch better.

Am i the only one with a ATI card that has this problem?

No - I have the same problem but don't have a solution, and I've tried everything. Maybe Coastie can give us some insight?

AFAIK, it doesn't matter what card or drivers you use. It's caused by the breaking wave animations on the beaches. The only solution is to use higher resolutions (it's much reduced at 1600 x 1200, for instance) or to use hazy or worse weather which masks it in the distance.

Given that clear weather seems to give he same viewing distance as one might find on the Moon this is not necessarily a bad idea.

Cheers,

RD.

Sure thing. Here are five similar shots.

What am I supposed to see along the shoreline. Really I must be going blind but I don't see it so far. Sorry http://forums.ubi.com/groupee_common/emoticons/icon_frown.gif

Waldo, you don't fly with AA on do you? Doesn't look it from your pics in which case, no you wouldn't see anything strange about the shoreline. The problem is the shorelines are jaggy and not smooth like other straight lines are when you use anti-aliasing.

I think "transparency anti-aliasing" on the newer nVidia cards might take care of that, but you're out of luck with ATi. The problem is probably the alpha channel on the wave-breaking textures, as RocketDog said.

Actually, forcing a filtered anti-aliasing mode in the drivers will probably take care of it. With nVidia cards you could use Quincunx or the unsupported 4x 9-Tap (Use Rivatuner) to get rid of the shoreline jaggies, but everything will be pretty blurry. One of the supersampled modes (4xS, 8xS, 2x2 SS, etc.) might help, too, but they'll kill performance.

I don't know if any legacy FSAA patterns are hiding in the ATi drivers, however. I think nVidia is alone in that.


Hmm... from looking at the screenshots again, it looks like ATi's 6x sampling pattern just sucks at horizontal lines. There's not much you can do about that, but I have a hunch that 4x might do better with shorelines.

Sorry! http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif But I don't get it still, I don't see anything jaggy with any picture in this thread.

Retook the shots with AA & Aniso to 4.

No matter what pictures I look at in this thread, I don't see a problem or understand what the fuss is all about.

Shoreline! Got it, but sadly I don't see anything wrong, like you all. (I am not denying or challenging anything - just not seeing it. Sorry I wish I could help some. http://forums.ubi.com/groupee_common/emoticons/icon_frown.gif ) Best of luck fixing whatever it is you are seeing.

I see it in your shots Waldo...the shoreline is aliasing. Mine does too. I think everyones does. There's a hard line between the land and the pixel shaded water that AA can't do anything about. The engine seems to render this hard edge at a distance in a way that aliases fairly significantly.

I've not seen any configuration where this didn't go away. Its better at higher resolution...AA can't seem to do anything about it. ATI or nVidia. Not sure about transparency AA...

Transparency AA won't fix it. All you can do is set AA to 8s or 8. But on ATI cards there is no 8*AA. All settings under 8 make the shoreline jaggy. I've asked Oleg about this a few months back and he said that it was a NV driver issue (had a 6800le back than). I've asked for a solution at ATI now. Hope they can fix it in the next driver.

Here is an attempt to explain the problem again:

http://i99.photobucket.com/albums/l304/vanderstok/misc/AA.jpg

Please note:
1. in this picture you'll see some "anomalies" on the edges, these are caused by the compression to jpeg. You should look at raw bitmaps to get a good idea of the quality.
2. Waldo, if you make screenshots and resize them to a lower resolution (at least it looks that way to me) than you will not see the missing AA effect, because resizing in a paint program/or photobucket normally applies anti aliasing as well, thus smoothing out the edges.

Anyway, when you run a high enough resolution it isn't a big problem, but graphics freaks like me do tend to notice these things. (Then again, I have a friend who doesn't really notice the difference between AA turned on/off, so he wouldn't care less about this problem... http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif )

i have a suspicion this problem can varry significantly depending on the FoV used.

Vanderstok,

could you post the same screenshot view for the 3 settings of 90 (wide), 70 (normal), and 35 (not zoom view, but smallest FoV). plz keep it in a lossless file format (tiff etc), what resolution are you using , and what is your monitor size ?

i suspect the problem is much less in the narrowest FoV for smaller monitors monitors, and that large monitors (above 23' roughly) dont have the problem on the wide views.
