Questions about VR Execution Errors,Audio Errors and Resizable BAR Errors (ARC A770 16gb)

[MSAPR]

I am using the motherboard BIOS that supports ARC and the graphic driver used both the latest and beta

But Currently, I am struggling with two errors.

1.Unable to play VR games.

(EX:VRCHAT,Halflife etc)

I am currently using a virtual desktop program and have adjusted various codecs and graphics options

However, it only runs up to STREAMVR, and most VR games are not played after that.

2.The audio keeps stuttering.
I am currently using the audio interface, but I have the same symptoms when I do not use it

It's not constantly stuttering. When switching programs or taking certain actions, the audio is slightly pushed back.

It can't be used on Windows basic audio or regular speakers, and it feels good if I increase the buffer size a lot when using the audio interface
(It is not a problem with the audio interface or other parts of the computer. Before replacing with arc, I used the same part and tried it on other computers, but I have to use X2-3 the normal buffer size

Before replacing with ARC, there was no problem with the same parts and environment.)

It's really hard when I work on music.

BUT!!!!!!!!!!!!!!

Surprisingly, all of these problems work fine just by turning off the Resizable Bar option.

Maybe it's a problem with PCIe or other options, so I've tried a lot of BIOS, audio environment, graphics options, and Windows options, but I can't find the answer anymore.

Please let me know if you have any idea or if you know how to solve this problem.

Once again say, I used the graphics driver has used all previous versions, current versions, and beta versions
BIOS audio windows have also been replaced and combined, but there is no solution at all.

Thank you for reading

Hello MSAPR,

Thank you for posting on the Intel️® communities. I am sorry to hear that you are experiencing issues with your ARC A770 16gbs. We appreciate your patience.

In order to have a better understanding of your issue, please provide me with the following:

• What do you mean by saying that VR games are not played? Doesn't the game open?
• Are you getting any error messages when playing VR games?
• Do you experience any issues when you are at the STREAM VR?
• What VR headset are you using?
• Are you able to use the integrated GPU, and check if you can replicate the audio issue?
• What type of program causes the audio issue once you switch to them? Are they heavy-workload programs?
• Create a report using the Intel System Support Utility (Intel SSU).
  • Download the Intel SSU
  • Open the application and click "Scan" to see the system and device information. By default, Intel SSU will take you to the "Summary View." 
  • Click on the menu where it says: "Summary" to change it to "Detailed View." 
  • To save your scan: click "Next"; then "Save."
