Screen Replicator "Tool" Viewports Flicker Sporadically

[MadKreator37]

Not much to say currently except others have had this same issue. Just logging it here.

• Aircraft doesn't seem to matter
• Number of replicated viewports doesn't seem to matter
• Refresh/ update rate of the replication doesn't seem to matter
• Also doesn't happen all of the time.
• Almost like interruptions in the data stream.
• I have done anywhere from 2 to 5 or 6 at a time, some will flicker, some won't.

DCS: current and past versions
Helios: Current and past versions
Occurs when running a profile via Control Center

• Need to gather more info and maybe some control center logs

Here are logs from Sobe after it occurs:

Control Center.log

Almost like interruptions in the data stream.

No data stream involved with the screen replicator. It is a memory copy. Nothing obvious in the attached files (but I wasn't expecting to see anything in there for this type of problem).

I have done anywhere from 2 to 5 or 6 at a time, some will flicker, some won't

always the same ones flickering, or different ones. Do they still flicker if DCS is not running?

Is the flickering affected by G-Sync/Free-Sync being on or off?

Removing "Bug" label because not clear at this stage that the problem is related to Helios.

| always the same ones flickering, or different ones. Do they still flicker if DCS is not running?

• well Sobe has a couple in the f-14 that do it. I have had it do it in the f-16, f-14 when I trialed it, and another aircraft ( I believe the chinook,, when you first introduced the feature.
• Sobe's replications flicker like one or twice a second.. when I see it its only once ever 8-10 seconds.
• • theres no viewport to replicate when dcs isn't running.... but I will ask him to run the profile and see what it does

| fickering by gsync?

• I don't run either or v-sync.. I will see about Sobe.

• I do typically use DLSS though

| always the same ones flickering,

As an example, you have a single profile with 2 screen areas being replicated (A & B). If you run the profile once, is it only A that flickers, or sometimes A, sometimes B and sometimes both (over the same test run). If you run the same profile multiple times, do you observe exactly the same issue? The capture frequency is per replicator so is the flickering related to that frequency? Does increasing / decreasing the frequency alter the flickering... if so how?

theres no viewport to replicate when dcs isn't running

That's the point. I'm trying to understand whether the flicker is related to the capturing of the screen area, or whether it is related to how DCS is painting the viewport data.

Both the A and the B view ports flicker. You can view the flickering in 2 videos that I uploaded in CZ's Discord in the F14 channel.
Changing the frequency does not seem to stop the flickering. The flickering starts as soon as the cockpit of the F14 appears on the screen even before I hit the fly button. If you need any additional info, let me know. This is my first post ever on Github.

You'll be contributing code to Helios before you know it now that you are on GitHub.

Does the flickering change in any way (eg increases/decreases) when you change the frequency. What values for the replication frequency have you tried? Have you gone up to 60Hz?

[sobe1205]

I have used 5 10 and 30 with no changes in the flickering. I will try 60 later today and retest lower numbers.

I just tried it again at a frequency of 60 and the flickering seems to be faster (worst).

BTW, I should mention that I am not using a virtual monitor but about 1/4 of my third monitor as can be seen on my two videos.
