It doesn't support G-SYNC!
Quote: | The Samsung S95C is not officially compatible with Nvidia G-Sync, but it supports AMD FreeSync Premium Pro, which provides similar variable refresh rate (VRR) functionality. |
Quote: | S95C TV Specifications
Screen type: Quantum Dot OLED
Refresh rate: 120Hz
HDR support: HDR10, HDR10+, HLG
Audio support: Dolby Atmos, DTS
Smart TV: Tizen
HDMI ports: 4 HDMI 2.1
Built-in tuner: ATSC 3.0
Screen size: 65 inches
Resolution: 3,840 x 2,160
Video inputs: HDMI, RF, USB
Screen brightness: 888.9 nits
Black level: Not specified
Contrast ratio: Infinite
Refresh rate (1080p120): 1.8 ms
AMD FreeSync: FreeSync
Nvidia G-Sync: None |
Quote: | The S95C OLED TV has been reported to experience G-SYNC stutter issues, particularly when used as a PC monitor. Users have noted that enabling G-SYNC can sometimes lead to stuttering, especially in games with fluctuating frame rates or demanding graphical scenes.
Some users have found that disabling G-SYNC or using VRR Control can help reduce flicker and stutter.
Additionally, users have reported that certain settings, such as enabling V-SYNC in the NVIDIA Control Panel, can exacerbate stuttering. It is recommended to experiment with different configurations, such as capping the frame rate to a multiple of the monitor's refresh rate or using tools like RivaTuner Statistics Server (RTSS) to smooth out frame pacing. |

I know but it shows as G-Sync compatible,I thought that should be enough to get stutter free gaming at varying framerates, even with Nvidia GPU?

The pendulum demo is working fine so that is strange.
Maybe I didn't test enough games or there is something in Nvidia Inspector I got to change?
However I tried the same COD on the FreeSync Laptop display I got and there the variable refresh is definitely working without stutter.

That is interesting, so it might be a firmware issue? Sounds like an AI answer though.
I tried all V-Sync configurations. There is no VRR Control option. Not sure RTSS will work..maybe worth a try.

G-Sync and G-Sync compatible are not the same.
From my experience and talking to Avi, G-Sync compatible really just means: Freesync and wish you luck on G-Sync it should be ok more than 1/2 the time. G-sync is certified to work with G-sync cards. Freesync (G-Sync compatible) is "It works but we didn't test all situations. Your mileage may vary"
I (well he...he has a LOT more daily experience on customers rigs) have yet to see a situation freesync works flawlessly with Nvidia GPU across the board for games.
None of the freesync monitors in my house is trouble free trying to use g sync. My sons PC it's just turned off, 1/2 his games sucked in it. My daughters is better but she only plays 3 games and they all are fine.
G-Sync monitors have an embedded G-sync module your card talks back and forth to. G-Sync compatible (freesync) has a freesync module that is middle man that translates between what your monitor wants, and what g-sync wants (kinda..but rough enough analogy).

Quote: | While the primary function is the same, G-Sync monitors have direct communication pathways with the GPU, which potentially results in a more reliable performance. Meanwhile, G-Sync compatibility relies on the standard protocols and may experience a few variations (which depend a lot on the monitor and GPU being used). |

Yeah, both games I tried have exclusive fullscreen, I have the opposite problem with borderless fullscreen not working. AC Oranges forces me back to exclusive fullscreen every time. Don't believe that issue is connected though.
@SumZero
I know about the seperate G-Sync chip but didn't expect there still to be so many problems in practice with FreeSync after all those years. Sounds like some of it may be intentional..
Gotta test more games when I have time.

I don't think it's intentional. More freesync can only do so much to be compatible with proprietary hardware modules they cant see the raw specs and 'workings' of since its Nvidia property.
Nvidia made it, Gsync is directly connected. Freesync just gets to talk thru 'API' to it, so to speak.
They could reverse engineer one, but that's a whole legal can of worms if they did.
I see it sort of like using a USB adapter, to old PS2 for a mouse. Both interfaces are valid mouse interfaces. But using a PS2 mouse through adapters to get USB to talk to it expect weird compatibility issues in some software.

It boils down to the TV not having/supporting G-SYNC. You're out of luck. I guess you have to use normal v-sync.
Quote: | It’s worth noting that while the Samsung S95C does have VRR support, it is not currently compatible with Nvidia’s G-Sync. This is because G-Sync is a proprietary technology developed by NVIDIA, and it is only available on select gaming monitors and TVs.
That being said, AMD’s FreeSync technology is just as capable as G-Sync, and it offers a broader range of compatibility with different hardware. So while the Samsung S95C is not compatible with G-Sync, in no case does it downgrade it as an excellent option for gamers looking for the ultimate TV for gaming purposes. |
