Refreshrate issues

Hi, I have been using my first Intel Arc for about a week or two now. I've noticed some issues mainly related to the refresh rate of my monitor. I have the B570 connected to my Asus VG27AQ1A. I saw that people have ran into this issue before where Windows doesn't show the option to select 144hz, only up to 120hz on monitors that support 144hz. My issue is that after I update my drivers the 144hz option goes away. It it is possible to select it when i change the Display Port cable to a different output on my card, though it seems to recognize my monitor as a new device. I imagine if I update my drivers again that I would need to switch ports again. And another issue I face is that primarily in DX9 games that are locked to 60fps like fighting games, having variable refresh rate turned on in the Intel settings makes the rate of frame look worse than it actually should be, but if i turn it off these games look great. for example, my monitor will be at 120hz and then drop down to 60hz or anywhere in between. Thanks in advanced

Hi Umbasa,


Thank you for sharing your recent discovery on this matter. Using DDU is indeed beneficial in these situations, as it thoroughly removes the previous driver from your system. This ensures that when you install a new driver, it's akin to a fresh installation. Regarding the VRR issue, as I mentioned earlier, it reduces your refresh rate and FPS because it dynamically adjusts the refresh rate to match the game's frame rate. As such can you tell me if we can close this inquiry?

Hi Umbasa,

Thank you for posting your concerns in the community. To better assist you, could you please answer a few questions:


  1. Do you know your DisplayPort version?
  2. Have you tried using HDMI 2.1 for testing?
  3. Is your system newly built? If not, did you use a different GPU before?
  4. Have you installed version 32.0.101.6262?
  5. What is the current resolution set to your monitor?


Additionally, can you try selecting 144Hz by following these steps:


  1. Access the advanced display settings under the display settings.
  2. Click on display adapter properties.
  3. In the pop-up window, navigate to the monitor tab and select 144Hz from the list.


Lastly, Variable Refresh Rate (VRR) dynamically adjusts the refresh rate to match the frame rate of the game. This is why the game may look better if VRR is turned off.

Thank you for the response, I built the PC myself, previously using nvidia 10 and 16 series graphics. The monitor should be DP 1.2. I did DDU the nvidia drivers out of my system. I am on the 32.0.101.6262.  The HDMI port is being used by my secondary 1080p monitor, my VG27AQ1A is using the Display Port, the cable has been reliable when using the nvidia devices. additionally in my response to MUC I experienced another oddity in my display with a strange flickering effect, almost looked like it was the brightness going up and down. During that time my monitor was at 2560x1440p 120hz, HDR was off and it was fixed when I replugged the DP cable.  I'd be interested if in the custom profiles in the Intel Graphics Software if VRR could be turned off on a per-game basis as a fix, I don't think that is an option at the moment. And to further reiterate, the 144hz option simply hasnt been an available option most of the time I have used the Arc, where with the nvidia it never was an issue.

ASUS TUF GAMING VG27AQ1A

2560 x 1440 @ 170 Hz

VESA AdaptiveSync

1 x HDMI 2.0 TMDS

1 x DisplayPort 1.2 HBR2

 

Arc B570

1 x HDMI 2.1 FRL

1 x DisplayPort 2.1 UHBR13.5

2 x DisplayPort 2.1 UHBR10

 

Connecting via a DisplayPort cable is the right choice.

 

If you have not activated the overclocking function in the monitor's On Screen Display (OSD), the monitor reports 165 Hz as the maximum to the graphics driver. As expected, this happens in the form of so-called Detailed Timing Descriptors (DTDs):

MUC_1-1738767191411.png

 

The areas marked in yellow are parameters that deviate from the VESA standard Coordinated Video Timing - Reduced Blanking (CVT-RB). I'm starting to get the impression that Intel drivers have problems with this. Changing the port shouldn't be necessary. Perhaps the graphics driver team can take a look at this problem (EDID attached).

I actually did try clocking my display to 155hz (minimum setting they have) I just double checked because i thought it would show options for 120hz and 155hz in Windows but it doesn't, just 120hz still. also when i did switch ports to get 144hz to appear again and rebooted 144hz yet again disappeared.  Also last night when I was playing Dragon's Dogma 2 my display was having an odd flickering effect that persisted on the desktop after I closed the game. It did go away when i replugged the Display Port cable back in. I've never seen anything like that before and it had me a little worried. I hope all of this is just on the software side of things that can be remedied with updates.

Hi Umbasa,


Thank you for sharing your answers with me. Upon reviewing your processor details, I noticed that the issue began after updating to version 101.6262. Could you please let me know which driver version you were using prior to this update? Additionally, have you tried rolling back to the previous driver that was working perfectly for you?


Also, thank you @MUC for providing this information. I appreciate it and will include it in my notes.


Best regards,

I do believe I noticed it happening on the initial driver for the B570, 101.6257. Then when I updated to 101.626, the option for 144hz was present until I restarted my pc if I recall correctly.  From what it looks like to me, it is when I have a new driver install the 144hz is available until I reboot. I haven't double checked yet but I will soon. to clarify I don't think there was a driver version where the 144hz option was consistently available. Thanks

Hi Umbasa,


Could you please try rolling back the driver to see if the latest version is affecting your refresh rate? Specifically, try using versions 101.6256, 101.6257, and 101.6252. All of these drivers are WHQL certified. When installing, please make sure to select the custom installation option and check the clean installation box.

Hi DhannielM,

 

I seem to have good news. performed a clean install of 101.6259. and then 101.6257, both using the installer's "Clean Install" option. I had coincidentally had an issue with the IGS where it did not seem to be running and wouldnt load when I used the shortcut. both rollbacks didn't solve the refresh rate issues. I then noticed the 101.6559 had released the day before. So, I used DDU to clean out the drivers and install the new one. It seems that the 101.6559 has fixed all my issues however, I am interested if it really was a case of me needing to have used DDU for when I first updated my drivers to whichever version that was that released after the initial B570 driver, or if the latest driver implemented better support for my monitor

edit on 2/13. i can't be sure if the VRR issues are fixed or not, and if i should open a new ticket for that, but the 144hz is still working great!

Hi DhannielM.

 

Yes, I'm familiar with how VRR works, im just concerned with how the games I play that are made with a 60fps cap don't look as smooth with my Arc using VRR compared to how I remember the same games looked with g-sync. I'll do my own investigation before I consider opening a ticket about VRR.
