graphic errors when it is raining

hi Marek and Filip, i have some graphical errors since Update 1. I use a try a old version and there is no artifacts in older version of COI. I try different games setting to check if i fix it over change the graphics setting but didnt find any way to solve it.

The issue is "rain" related so it only happend when it rain. Than you will see in the left corner of the screen "black" boxes popping up as i move the camera it will also happend in close up of buildings.

My system is a
7800x3d
7900 XT
32 Gigabyte of Ram

Everything run without OC. I dont have any graphic anomly in any another game that i check and the GPU is new. The location of the artefacts is everytime the same corner of the screen never right side or lower corner always left side top corner.

Found the issue related to it. The MSAA is causing this flickering. So only when MSAA is on and rain is enable it cause this. Strange SMAA dont cause any flickering.

We run some extensive test with this save here:
Poly.save
and found the issue on the following AMD cards 7900 XT and XTX and 7600x. So basicly every new gen AMD card has it.

It seems that the issue is with fog:

@McRib33 [github] We've made some changed in the fog rendering recently, could you please test whether this is still happening in v0.5.3 or later? Fog is denser in rainy weather so it is more visible. Zooming out to see more fog may also make it more prominent.

If it still happens, could you test whether this is happening only when camera moves? What camera movements make it trigger? Forward/backward, or sideways, or rotation, or all?

Additional details such as driver version would be also helpful.

Thank you!

Thanks for update 0.5.3a it greatly reduces the amount of flickering. I see less fragments that seem to be faster vanishing as before in the video.

I tested different camera movements via Keyboard and Mouse. All seperataly and i found the flickering on each of them. So mouse input and keyboard input even moving only sideways created flickering.

I have now flickering mostly on ground and sometimes on a mountain that is a bit away as in picture 2.

Thanks for the picture that fit with my finding will upload a picture of a another game and it show the excalty same issue (i hope that help to pinpoint what causing it)

It is not "normal" to have this triangle in the corner and it is flickering was very hard to catch it on a picture. The game is normaly 100% without any flickering ONLY happend when you use a filter so for example when you open a windows that "reduces the brigthness of the game." I call it a filter not sure how you would call it.

Both games use unity as a engine by the way.

@McRib33 [github] We have published a special build on beta branch testing-fog on Steam, could you please try it out and let us know if this bug is still there?

Thanks i tested it it seem to be quit the possite in what it is suppose to do.

And no the issue is got even a bit worse (much more visiable now) because of the amount of fog. Not sure if that was the intended amount of fog. But now it is much more clear to see that the filter is causing this. However im still not sure why only in spefics "spots" on the screen. (left side to middle of the screen - a bit over it - but never on the right side). Close ups show also the same amount of artefacts.

The artifacts are now flickering the same way as the another games (against the storm). So instand of just showing up 1 time they pop up 2 times until they vanish again if it the camera don't move anymore. (So the camera trigger the first artifact and it vanished and after 1 second it show up again even if the camera didńt move anymore)
