fixed Screen flickering since 2.5.4

@discwalker

I see we have same hardware for ram and gpu and i have make a test with Su-27,

I notice you have flickering with mirrors on and off but for me it's always the same when i put mirrors off, nothing, look at that...

but after that i've try to climb around 14km, disable mirrors and at a certain moment having a very few flickering with in my sight sun and lake, just 2 or 3 blincking, i try to reproduce it for capture but i've failed.

No problem here it is:

I'll try to delete fxo and metashaders and report if it change somethings.

no change after delete and repair, so i'll play without mirrors.

Did you delete both metashaders and metashaders2 folders? Was worth a try.

I watched your 15min track file 4 times and recorded what i'm seeing and uploaded it to YT, i hope it will take them not to long for processing the video to a better resolution than 360p(should be 4k). But to make it short, i never saw flickering in these 4 times watching your track.

I posted my in game settings in this post, could you please try to set these(except the resolution ofcourse), restart DCS and test again. Just to be sure it's not only a setting that messes things up with some HW combination.

At 14km altitude around Sukhumi, towards the sun.

Su-27 mirrors on/off, flickerings started from spawn.

(Settings in video ending.)

 

Please react, ED!

I watched your track 8 times, never saw any flickering, I will have some time at the weekend and will try the track with your settings

i have strictly respect this:

- delete the fxo and metashaders2 folder in your C:\Users"your user name"\Saved Games\DCS.openbeta

- delete the metashaders folder in "your drive":\DCS World OpenBeta\Bazar\shaders\

- run the DCS repair

- run DCS

Should i delete the metashaders too in "Saved Games\DCS.openbeta", i'll try it now and try also to change internal config like you say but i've already try a lot of combination with IC (water, lens effect, fullscreen ).

Could it came from RAM instead GPU?

Ah, ok. Just wanted to be sure. Yes you can delete the metashaders in your saved games folder, this one shouldn't be re-created by the game. At least i have only the metashaders2 in my saved games/dcs folder. I don't think this is a RAM issue. I had similar flickering last year only in the Viggen with the Radar active(only on Radeon cards), that was a game bug. And like i sad, i had this flickering too as it was introduced with one of the December updates but after they fixed it with another patch all is fine again on my side. My guess is a shader/shader cache problem.

I've retry to delete and repair and other IC, issue persist, for ram i'm not conviced too just suggest it, and for me it's also a shader issue due to compatibility with some HW (does not matter nvidia/radeon), Discwalker have flickering too and we have similar HW (GPU, ram).

I understand it's really hard to solve because of the variety of HW but it's a really annoying issue, i hope ED can resolve it shortly.

Is anyone in here experiencing water flicker from within the cockpit? It's gotten pretty bad in the MiG-21 and F/A-18, but I don't experience it with the AV-8B. It's only the water that's flickering for me.

Two months or more now without a solution to this problem? Really? This has made the Gazelle ans Su25 pretty much unplayable for me. It's been a month since anyone affiliated with ED has even posted on this thread. What gives? I have not been playing DCS that long comparatively. Is this lack of support for a major bug such as this the norm?

I hope this will help to solve the issue

Recreation of todays MP landing: horrific

I matched the place, date, time, flight path was a harder and closer turn to runway

edit: preset low+medium+VR settings: no flickering (blank mirrors)

edit: preset high settings: yes flickerings (working mirrors)

Nineline here is what Im seeing. In the screen shots in the A10-C when I see the sun reflection on the canopy I get the black flashing but when I look back for the sun its not there. If I cant see the sun why am I seeing the reflection on the canopy? I can reproduce this every time with the A10.

To note if I fly the AV8B in the same mission and see the same reflection of the sun on the canopy i get no flashing. What is the difference between the two planes canopies.

Nine... quick question.

Do you know if ED tests with AMD GPUs?

It seems odd that you are reporting the issue cannot be reproduced when there are so many reports of issues among players with different hardware setups. AMD seems like a common theme. Which is why I ask.

I was able to replicate the issue with every driver set going back to August 2018 on my Vega 64 (Windows 10 1809....it took a minute but hopefully worth the effort).

The issue itself doesn’t go back that far, but it does seem to point more solidly to a recent change in DCS since no difference is made taking GPU drivers back long before the issue started.

Next I am deep diving into DCS logs to correlate modules that flicker with ones that don’t looking for warnings and errors. Maybe something will turn up.

Yes it is Im getting the same flickering that everyone is getting that you can see in the videos in this whole thread. I can reproduce the black flickering every time that I see the suns reflection. Its very hard to capture the flickering in a screen shot. I should have not said flashing.

Screen Flicker

I took the time to make a video on this ongoing problem. Sorry if I sound a bit heated about it but I really did enjoy flying that helicopter (Gazelle). My friend bought it and we were going to fly together but I can't fly with this bug. I understand it's hard to track it down but pleas try. I have an AMD 4core @ 3.2Ghz. 21 gigs of Ram and a Radion RX480 graphics card with the latest drivers. The game runs fine but the bug that emerged a few patches ago, eliminates this module as a choice for me. Occasionally I see the same flicker in other aircraft, but not nearly as bad.

A link to a video I uploaded showing the offending problem. I hope someone in development sees it and something clicks about what is causing it.

Thank you in advance!

*screams internally*

Plenty of Nvidia users have reported flickering; these are just from the first two pages:

For the love of God stop this AMD GPU nonsense, giving the devs wrong information does not help them. And yes, the issues started exactly with the first 2.5.4 build. Reverting back to 2.5.3 removes the flickers.

[REPORTED] Screen flickering since 2.5.4

I did not say it was an AMD exclusive issue. I am pretty sure I wrote the opposite as well as stating the issue is not related to drivers going back to Aug 2018 after testing every version between then and now.

FYI, I am going to offer to send my Vega 64 to ED for testing if they are not currently testing on AMD to help solve the issue (more data points to narrow it down). That is why I asked the question and provided AMD specific info.

Thanks NineLine.

My offer still stands if needed. DCS is the only game I play and it would be an honor to play a small role if it would be help.

More details...

With the Gazelle the issue is related to the spinning rotor blades. If you Zoom in the view until the blades are no longer on the screen (or look back at the rear seats...same result with blades out of view) the flickering stops.

For me with NV or ATI

It is the screen space reflections.

Any light reflected back at the canopy may produce a corona effect.

This is where i see heavy flickering.

Complete showstopper.

Worst case - approach, break, runway

I hope this madness causing flickering will fade out soon.

In Su-25T it depends on the mirror state.

suggested replay method: preset high graphics or with my settings

Cool, hopefully bug #1 was causing the dynamic weather water flickering with cloud shadows too. Two birds one stone.

Ok guys, I have an update for you via Rik.

 

There were/are a total of 3 bugs.

 

1 was related to sea shaders and was fixed and merged already (solved for some of you)

2 is related to mirrors and the fix is ongoing

3 is related to the SA342 rotor blades and the work is also ongoing

 

So 3 different bugs, all a similar result, 1 down 2 to go. Hopefully, they will be resolved soon, but at least with this, you might be able to avoid it a little more till then. Thanks for everyone sharing their experiences, it always helps the team ID issues so much faster, even when not all of us can reproduce or experience the issue.

Nice! Does this mean that disabling mirrors will remove the flickers?
