How To Stop Screen Flashing?

[Cavalstone]

There's an annoying screen flicker/flash that happens very regularly when the game is running.

Has anyone else seen this? Any ideas on how to stop it?

Thanks for your help.

I have the same problem and no solution so far. It looks like the screen is toggling between night/day for a microsecond. My first idea was that it has to do with the Time Warp mod, but the problem persists after deactivating the mod.
Any help would be appreciated.

Even if you deactivate the time warp mod it still loads into the game memory. Remove the mod entirely and see if that helps if not try not using vertical sync perhaps

Already tried all the v-sync options to no avail. It definitely has something to do with the day/night cycle because the issue disappears when it's deactivated.

UPDATE: Removing the TimeWarp mod completely actually solved the problem. Thanks a lot. :)

I checked the description of the mod and it said Flickering issues may persist

A two year old thread, but I got it fixed by simply going into the Graphics settings and changing my resolution to something else and switching back.

The ingame resolution, or the windows/nvidia reslution? because i try in game resolution 1080p to 720p and retruning to 1080 and the flickering is still there.

I have that too and noticed only yesterday that if I change the „shadow distance“ option to „short“ it significantly reduces the flickering.

Well, I only did it in-game and it worked for me. There are many things that could cause flickering, each with their own solution I suppose.

Could be a mod breaking your game, maybe? It's pretty hard to locate the conflicting mod if you have a lot of mods active, so good luck with that.

From further testing in a strict vanilla setup I currently conclude this is not mod related. Though mods may perhaps affect the dimension of it.

It clearly appears to be something around the way the game renders shadows. Turning shadow quality off let's the flickering disappear as obviously no shadows = no shadows that can flicker.

When setting shadow quality = low and shadow distance = very far I can see wobbling shadows all over the place.

With shadow quality = high and shadow distance = very far the effect improves on shadows of nearer objects but still flickers and the shadows of further away objects still awfully flicker.

I confirm turning day/night cycle off does further decrease the flickering effect but it does not completely disappear.

Have you done a clean reinstall of your graphics drivers? If not, try that.

Yepp, several times already. I completely DDU'ed in safe mode, restarted, tested with Win 10 default drivers, still flickering. Installed latest available Geforce driver 411.70 of Sep 27th 2018, no cure so far and thus that is not the root cause.

I am currently running thru all the background tasks running on my system. And I found that particularly disabling stuff that could pop up an overlay in game further improves the situation. I already had disabled the overlays of Steam and Nvidia. I now additionally fidentified that Uplay as well as Discord are also running overlay processes and that killing / disabling those helped.

Shadow flickering is still there but has become significantly less.

Edit: Found 2 other settings that helped further reducing the flickering effect.

• If using Relight mod there is a setting called "Disable Shadow Smoothing". Deselecting that helps.
  
• If using Shicho mod there is a setting called "Self-shadow mitigation". The further to the right you move the slider the less the flickering.

Okay, first thing first. You must type a: -windowed.
It's works on Cities: Skylines without flickering.
