VRR supported and enabled, but not working

[KWottrich]

I have the 2024 LG Gram Pro 16, which is equipped with the Intel i7 155H, and does not have a dedicated Nvidia GPU onboard. The screen is a 2880x1800 OLED display with a 120Hz refresh rate connected via eDP, and the hardware ID of the display is SDC41A5. I am running Windows 11 Pro 24H2, and I have Intel Graphics Driver 32.0.101.6458 installed (which I downloaded from the Intel website after deleting all older versions of the drivers with DDU).

My problem is that Windows and the Intel Graphics Software both report that my display is VRR-capable, and I have enabled the feature everywhere I can find, but I still experience significant stuttering during games as though VRR is not working.

As a note, I have tried enabling and disabling the "Dynamic refresh rate" setting in the Windows Advanced Display settings, but the stuttering persists in both cases.

I am using VRRTest to quickly verify the stuttering, although I experience the stuttering in every game I try, as well as when using Moonlight to stream from another PC.

Any help would be appreciated! Let me know if there's any other information I can provide, or configuration changes to test. Thank you!

Hello KWottrich,

Thank you for posting in our communities.

May I know what specific games you are trying to play that the issue occurred with?

Is it possible that you can share with me a video showing the issue so I can better understand the problem? (If you can share the game settings while you record the video, that would be better.)

Furthermore, please generate an SSU report to help me further analyze your system specifications and configurations.

To generate the SSU report, please refer to the article: How to Get the Intel® System Support Utility Logs on Windows. Please send me the generated SSU.txt file.

I have attached my SSU output.

I also uploaded a video showing the stutter as much as I can. My phone can only capture video at 60fps, so I've slowed down the video to 1/3 speed to highlight the stuttering after I drop the FPS from 120 to 118. Under VRR, there shouldn't be any stutter, just a slightly-slower smooth display rate that shouldn't be discernable. In the video though, you can see the brief stutters and pauses after the FPS drops.

The specific programs that all exhibit stutter are:

• Moonlight-QT
• VRRTest (shown in the attached video)
• Guild Wars 2
• Destiny 2
• The Riftbreaker

An update! I have gotten VRR to work correctly by running my applications through Special K. I don't understand what about the injection process would be fixing the issue, but whatever behavior it does by default is enough for VRR to function correctly in every game I've tested. I have not changed ANY settings in Special K, either in general or on a per-game basis. Just adding my game to its list and running it is sufficient to get it working for me.

Hello KWottrich,

Thank you so much for your quick response and for your update.

Based on your last post, it seems that you have already fixed the issue with regards to the VRR. I just wanted to confirm if you have any queries or need further assistance from me. If yes, please let me know; I will be glad to assist you.

Hi Carmona! I wanted to let you know that I was wrong about Special K, it seems that VRR is working now even without running Special K but I don't know why or what changed from when I was having issues before. I did also notice that VRR works all the way down to about 48 FPS/Hz, but there is really significant stuttering between 57-63 FPS/Hz. 56 FPS and below becomes smooth again, as well as 64 FPS and above, up to 115 FPS. I can't think of why stuttering would be bad right around 60 FPS/Hz, but it's really noticeable for lots of older games and emulators that run locked at 60 FPS. Is there anything you can think of that could be causing the issues around 60 FPS/Hz?

As a related question, I have found it very useful on my desktop computer to enable the G-Sync indicator in the Nvidia control panel, which overlays any 3D application that is doing VRR. Is there any such VRR indicator in the Intel software driver/control panel?

Hello KWottrich,

Thank you so much for the response.

Let me further check the query that we have; I will get back to you as soon as I already have an update or answer on our case.

Hello KWottrich,

Upon reviewing the system requirements for the games, it appears that a discrete graphics card is recommended for a better gameplay experience. May I know if the games were working fine before and what is the game digital distribution serve are you using to play the games (Steam, Epic Games, etc.)?

Additionally, please use CapFrameX to further analyze the performance of the games. Ensure that you play each game for a minimum of 5 minutes to thoroughly assess the game performance.
