Bug QN90C 1430 firmware: VRR in GameMode flickers almost unwatchable

[Hellknight]

Devices

Samsung QN94C (NeoQLED) + XBOX Series X

VRR - Mode

AMD Freesync Premium on 120 hz

After testing the latest firmware for the QN94C I came to the conclusion that there is a severe bug in the VRR Code: When playing games like Diablo 4 or The Ascent I get ugly blueish (?) flickering in scenes with static content where are slight animations (loading screens, even slight freezes due to loading of textures).

This bug is not so bad with 60hz but its still there.

You can easily check this behaviour in "The Ascent" when you load a game. Or in Diablo 4 while switching to the skill tree or collecting the "Gold Urn" in the new Horde mode when you have around 700 aether where the screen gets frozen for 2 sec due to all gold which drops ou of that urn.

Disabling VRR doesnt show this behaviour.

At the moment with the current firmware 1430.3 I cant recommend the qn90/94C for XBOX gaming.

Hopefully Samsung fixes this problem asap...

Hi @Hellknight,

did you already try another HDMI cable?

Kind regards

Thank you for answering my observations.

Yes - the XBox Series X cable an an Oehlbach Flex Evolution both have the same symptoms.

60 hz mode (in XBox settings) reduces this problem greatly but not completely.

When connecting the Series X to my Samsung Q995C soundbar (only 60 hz possible) I have the same problem like the console is directly connected to the TV.

Does the TV still process the VRR when the XBox is connected to the soundbar? If yes TV may be the problem if the soundbar processes the VRR my XBox may be the problem.

Update - still not fixed with the latest OneUI Update. So this TV still shouldnt be used for serious gaming with XBox Series X.

I have the same Problem on my 55" QN92C. It has really bad flickering when there are frame drops below 70-80 fps. I also have the QN92D, which does not have this problem anymore so they have somehow fixed it in the new model. Samsung, please also deploy the fix to the 2023 model!

This is not good - seems we have to buy a new Samsung TV to fix this obvious problem...

Btw. still not fixed with the Update after the OneUI Update so it doesnt seem that Samsung is willing to fix this problem...
