Textures flickering on distant object
 

EDIT: please note that with further testing, distance (other than very close) and viewing through optics is not really a factor. In the case of the screenshot below, the factor was whether or not the ship had been damaged.

This is especially (perhaps exclusively) a problem with ships, particularly when view at a distance through optics. Certain areas of the ships have areas of black flickering across them. You can see a bit of this black flickering/flashing in the screen below, but of course it does not really convey the effect in a still image.

I'm pretty sure this is not a problem new to 1.2. I cannot find a relation to any in-game settings. Any ideas if a card setting might be causing this.

I have a pair of 6800 Ultras with latest drivers (although I am running the game on a single GPU as I lose FPS with SLI). 1280x960 w/ 2X AA

I have a similar problem (GeForce 7900 GS, 4X AA, 8X AF, 1400x900). Its quite noticeable when looking at ships in the museum, also.

Yeah, museum was the first place I noticed it after I installed the game.

Sounds like an issue with mipmapping to me - mipmapping being the technique used to scale textures in the distance to stop this kind of thing going on - you may be able to find something in your video card driver application to alter how this is (or possibly isn't) being applied.

Well, here's something interesting. I found the most obvious mipmapping setting on my card and changed it and then went back to the same scenario I saw the artifacts in above and it seemed gone...until I was messing around later and fired my deck gun at the ship and hit her once. All of sudden the flashing black areas were back along the whole length of the ship. Went to graphics options and slid the "3D damage" slider all the way to the left. The flashing areas went away again.

So, any damage seems to cause this to appear. However, even with the slider all the way to the left, certain areas of ships still exhibit these artifacts until you zoom all the way in (when viewing them in the museum). One of the most obvious areas is elevators on carriers, e.g. Bogue class fore and aft elevator:

The life rafts hanging vertically along the sides of ships are also prime suspects, albeit in a much smaller form.

I thought I had already checked this, but I double checked to make sure. Checking the Bogue's elevators in the museums shows that the huge areas of flickering are still there. Perhaps it is ameliorated to some degree for the small areas seen from the side of many ships, but the problem is definitely still there. I also inflicted damage on the two merchants in the navigation training mission and the random areas of flickering black immediately reappeared, as well.

Areas where there are horizontal lines that take on an angle as the ship rolls also have a "flickering" effect that I believe is unrelated. Perhaps the normal maps effect that, or perhaps this is improvement is dependent on card/drivers?

Anyways, I tested a bit more and noticed a few more things. First, the "ship damage" has three settings: right, middle and left. All the way to the right and a "3D" hole and the flickering appears after damaging the ship (although some hits in certain areas seem not to cause the flickering). With the slider in the middle, no 3D damage or any other change occurs, but the flickering is still there. With the slider to the left, there is no 3D or 2D damage and no flickering. This suggests to me that some sort of damage texture is supposed to be applied, but instead all I see is this random flickering on large areas of the ship, often on parts not associated with the damage just inflicted.

The only other way to make the flickering disappear (whether that which is always there or that which appears after damage) is to view the ship from very close range.

edit: I also tried to exit the sim and restart after making the change in the options just in case it didn't take immediate effect, but this made no difference.

I deleted my post cause when I restested it, it reappeared... sorry to PM for nothing..

I thought I'd found a fix but hadn't.

It isn't just the damage thing though, though it does reduce it on some ships, but not others. Look at the Yamato as an example in the Samar mission.

Anyway, I have tried everything I can think of...

Mipmapping levels,
AA
AF
I have diabled all the options in the graphics panel and it still occurs.
I have tried removing wakes
I have tried rescaling textures in T01 and T01_lr as well as corresponding normal maps.
I have editied the dat files to change the MediumLOD and LowLOD ranges.


NOTHING FIXES IT!!!

I feel it is either a LOD / texture missmatch, an interaction with sea effects or something similar


We know: It occurs with range (disappears zoomed in)
Not a graphic option
Damage = 0 does reduce it on some ships
Its not a normal map, cause I removed the normal maps from the yamato and although the ship looked a bit weird (light coloured) the warping was still there.

I am losing patience with this...

Was it present in 1.0 or 1.1 versions of the game?

I have this problem too. I have a Radeon X1600 so it seems to happen with both GEForce and Radeon cards.

Me too, are you Gents using nHancer?

twin GeForce 9700GTX SLI's.

Very noticeable on Sub Tenders.

Happens with my X1950XTX (Cat 7.3 drivers). I thought it might be z-buffer problems?

Cheers,

You're really far ahead of the game. :lol:

I've got it also useing an ATI X1650pro with Cat7.3's. As stated by the thread starter, as soon as ships take damage, the texture flickering takes place. I'm glad I'm not alone on this one. Definite immersion killer!

For the record, my 3D damage slider is mid-way. At a torpedo impact, sometimes the damage effect appears, sometimes not. But immediately on impact, the texture flickering manifests itself. I first thought it was a memory, or rather lack of memory problem. I have only 1gig, and the game plays pretty well at that.

Thanks been tinkering with those and nHancer on a overclocked Asus board.

There are a few SLI posts on nHancer profiles. We should all get pretty close on that eye candy vs. non-slideshow curve.

cheers :arrgh!:

The same here, Geforce 7800 GTX with newest drivers.
Flickering on many elements of ships, especially bright elements,
very frustrating, I hope DEVS can do something.
I tried many graphic settings without solution.

Definite immersion killer!

Ohh my! what's your FPS?

Tell us, tell us! :rock:

Flickering here as well
