I have fixed refresh set and also use maximum refresh rate set. V-sync disabled in sim and G-Sync turned off for all monitors, and my TV stays at 119/120HZ. If G-Sync was active and then disabled when the TV is turned on, It  reverts to VRR rather than G-Sync, so that could be the issue? 

@Cpt_Piett thanks for that. I will double check my settings to see what’s going on. 

As for changing the refresh rate of the LG… why would you do that? can you actually do that? And even if so, the reason for the VRR flicker is that the display charges the pixels based on a 120Hz refresh rate, and lowering the refresh rate (through VRR or presumably any other means) introduces flickering.

Perhaps. I had to turn G-Sync back on though, as I couldn’t deal with the screen tearing with it off. I guess I’ll choose the lesser of two evils. I’d go with low light flicker occasionally vs screen tearing most of the time. 

You don’t get tearing with both v- and g-sync off?

I was thinking there would be less risk of screen tearing with a fixed refresh rate closer to the output of the GPU. But I’m not sure. In NCP I have the choice between 120 and 100Hz in “PC mode”. In Win11 display settings there are more options e.g. 60Hz.

No, not at all. Not sure why?

It's subtle. Just tested again at Barra where there's nothing much around to stress the hardware. It's pretty smooth with a fixed refresh of 120 and no v/g-sync. Perhaps a tiny bit when panning in the external axis. I'll keep it like this for a while, it could be good enough.

If you have tearing, maybe try v-sync FAST in NV CP. That's what I'm using (no g-sync or v-sync in game) and it works well.

Yup, back to fast.

Hang on, perhaps I was a bit too fast there 😉

Fast sync is not supported for DirectX12 games. If a DirectX 12 game is launched with NVIDIA Control Panel Vertical Sync setting set to "Fast", the graphics card will automatically default to Application Controlled. In general, Fast Sync is designed to benefit games that are running with very fast native render rates (3 times or more the rate of the refresh on you monitor).

Hey Chris,

Did you ever get anywhere with the gsync flickering? I just picked up a 55 inch LG QNED85 (Mini LED) and have been experimenting with various picture settings. With VRR enabled in the game optimizer I am also getting a sight flickering as I pan around the cockpit with the hat switch on my yoke, I tried various refresh rates but haven't got rid of it. I am just doing my first real flight and settled for the following settings for now:

• VRR Off
• Vsync - Application controlled in NVCP
• TV Refresh rate - 100Hz
• In Sim - Vsync on @ half monitor refresh rate (50Hz)
• RTSS locked at 50 fps

I can maintain 50 fps in the Fenix & PMDG for the majority of the time and when I do the sim is super fluid and the frame time graph in Riva is a solid line, very consistent. It would be really nice though to be able to use the VRR feature on this TV but the flickering is a little too distracting for me.

It's important to note that the flickering issue I had is the result of a combination of a dark scene, g-sync, and low FPS. This issue is a well known problem with OLED displays. In a bright scene, no VRR, or higher FPS, you shouldn't have an issue.  I think the solution is a 4000 series Nvidia card with frame generation to increase FPS up to the 100+ range. Then the flickering shouldn't be an issue with G-Sync enabled.  Until then I will run with VSYNC set to FAST in NVCP and G-Sync disabled. I don't have any issues with this.

That's interesting Chris,

I was getting the flickering during the day and even when my fps were in the high 50's. I might try a different HDMI cable. It was worse when I had the TV set to 120Hz. I am still not sure Gsync is even working properly though. I set it up as per the blur busters tutorial and I am currently at 60Hz with Vsync - on in NVCP and using Riva to cap the fps at 57 but if the fps drop to even 52 - 54 range it is not smooth. According to the Game optimizer on the TV & the NVCP overlay Gsync is on and working but I thought if the frames were only dropping less than 10 it should stay smooth

If it’s on bright scenes, that’s probably some other issue.  OLED G-sync flicker should only be noticeable on dark scenes. If I was you, I would start with a baseline of settings and only turn on additional settings one at a time after thorough testing.

For example, try your display on its native refresh, no vsync in game or NVCP, no g-sync, and no frame limiter. Your only issue should be tearing. If you have other problems, then it’s probably time to try another game. It may be hardware, Windows, or drivers.

Then enable Vsync fast in NVCP and tearing should disappear.

Then try g-sync and check dark scenes for OLED flicker.
