Water reflections flickering on Ultra

[DanielCoffey]

I would like to report a rapid strobe-like flickering on the water reflections when playing on Ultra. There appears to be an extremely fast flicker on reflections in the foreground that may be associated with the sun bouncing off the water. It is most noticeable when facing the sun but is also visible to the sides. The closer to the foreground, the more I can see a striped texture on the reflections. It looks particularly odd when your deck is awash.

 

I am playing on Ultra but with 0xAA since at 1440p I don't find the AA is needed. Naval Action is Full Screen.

 

The graphics card is an NVidia 780ti 3Gb with drivers 347.25 at 2560x1440. While the card is overclocked, the flickering occurs even at stock speed. It is not overheating because even at 100% load the card reports 41C.

 

I had some spare time while my crew were busy with the pumps today so managed to capture the effect. Left side is with the flicker, right side is without. Images are JPEG 2560x1440 350Kb.

 

Let me know if there are any settings you want changed to assist with testing. I am tracking this thread.

Apologies for the large images - I thought they would appear in thumbnails.

Is that wind riffles by design?  Looks like little riffles on the surface from the wind.  If not, thanks for the screens, they will be quite valuable for the developers.  Also, hit F11 while you're seeing that and fill out the resulting report so the devs can see all relevant settings and information for troubleshooting.

Well they would match the wind direction.... The distortion matches the aparent frequency and length of the riffles. The shader seems to work on that behalf. Could be that something went wrong with the rifle frequency though. Id consider it intended as far as your screens are concerned. And might have while playing myself. Could be that is a nice effect that just looks shitty on a sinking ship. Best press F11 the next time and submit a bugreport.

 

Edit:

 

on your screens it aparently also transforms the sea foam, so I don't think its something wrong with the water textures.

+1 for wind rifles

Try messing with all the settings but throw the game on 1920x1080 and see what happens as well.

I observed it on High settings too last night. It seems to take a little time to occur -  in a fresh game everything is fine then after a couple of minutes it will begin. It has a very rapid strobing appearance on just that one effect or texture. The rest of the image is fine and the closer to the viewer, the more noticeable it is. Once it is occurring, it seems to come and go over a few tens of seconds. I will see it for a short while then there will be a little pause then it will flicker again.

 

I will set back to Ultra and F11 today in my next match.

 

Flip - my monitor is 1440p as its native resolution. Setting to 1080p will result in a very fuzzy screen. Is there something you expect that running at 1080p will expose (such as texture scaling) or is it "just try it and see"?

 

I have to confess it is a real bugger to capture in a screenie. I took a couple of dozen shots while it was happening and it appeared in only 4 of the shots.

I played three matches tonight and only saw the issue briefly so unless anyone else can corroborate, we will have to assume it is just my machine for now. I will file an F11 once I can reproduce it reliably.

I have submitted an F11 report of this issue tonight - about 20 mins before this post.
