FSLTL causes screen flashing/flickering?

[gal-m]

Hi all,

 

when I inject FSLTL traffic my screen flashes and flickers - more noticeable if I look at the bright sky and/or in the morning and evening, but is persistent no matter the "camera angle" - even in cockpit. It's obviously very annoying. 

I will attach a link to a YouTube video I have made in reference to this problem. Please note that the phone camera does not exaggerate the effect you see on my monitor, as it is even worse in real life - could probably cause seizures: 

 

 

Does anyone know how to fix this? 

 

More info: My game install is fresh and I don't have many mods: PMDG, Navigraph, two addon airports, FSRealistic Pro and that's about it. Have been using AIG in the past (it is now removed) and the game has been absolutely stable.

Looks like to me that your monitor refresh rate is now not being matched by your frame rate. It makes sense that it happens when your turn in FSLTL as this will decrease your over all FPS. 

This effect happens to me when I am using G-SYNC or Free Sync on my monitor. To solve it you must have in your settings VSYNC entables jn MSFS. It has to be locked to a fraction of your GSYNC rating that can be maintained. 
 

For example, my refresh rate on my monitor and NVIDIA setting is 120 HZ. So I lock my MSFS VSYNC to 33% refresh rate. That locks my FPS to 34 FPS. This can be maintained with out problem by my settings and the flickering is gone. If I did anything higher than 33% then the flickering would return. This is because I am selecting a FPS target for the simulator that cannot be constantly, so GSYNC is missing frames to create a smooth rendering. 
 

I hope this helps.

You were right @spearmint_flyer! I do have a G-SYNC monitor and an RTX 3090 and enabling V-SYNC seems to solve the issue.

 

Thanks a bunch!

I'm now experiencing the flicker on my main GSync monitor where MSFS will flicker the moment I pop out the TDS GTN750. and drag it over to another monitor. If I close the GTN750 window and just use the virtual cockpit one, the flicker remains. Its annoying,

So how exactly do I try your suggestion regards setting the V/Sync refresh rate as it sounds like I'm experiencing the same issue as the OP? It just might be a fix for me.

I do have Vsync enabled in the flight sim settings but that alone doesn't fix the flicker problem.

Try once, after you moved the GTN to the other screen, to Alt + Enter the MSFS screen, once to windowed and then back to «fullscreen». This might «reenable» Gsync.
