Problem latest drivers with OBS streaming software.

[Rongamer]

I have the Intel ARC-750 for my streaming computer the video card by the way did this fine but with the drivers 101.6299.

After updating the drivers to the latest version video encoder capabilities disappeared ( QuickSync ) ,
And that's a problem you can only use x264 which gives a lower quality.
My temporary solution is that if you start OBS with admin rights all QuickSync options are there again.
Somehow Windows 11 suddenly needs admin rights for OBS but this happens after the latest Intel Arc drivers.

This is not really a nice solution to the arising problem ( admin rights ) so I hope this gets fixed.

I have attached some picture for clarificatio.

Streaming system :

Mainbord : Asus Rog Strix 550B-F Gaming
CPU : AMD Ryzen 9 - 5900X
Memory : DDR4 32GB
Video : Acer Predator Bifrost Intel ARC A750 OC
Capture card : Avermedia live gamer 4K GC573
windows 11 - 10.0.26100 Build 26100

Can confirm this is a driver issue. I am using a Asrock Steel Legend B580 12G OC GPU.

I am on this driver version:
32.0.101.6559

Hi Rongamer, 

Thank you for posting in the Community.

I appreciate your efforts on providing this information. I want to know more about the issue so I can assist you effectively.

Did you do recent changes with the system? 

Have you performed other troubleshooting steps? 

Have you tried performing a clean installation of the driver using a tool like Display Driver Uninstaller (DDU) before installing the new driver? You may follow the instructions here: How to Use the Display Driver Uninstaller (DDU) to Uninstall an... Clean Installation of Intel® Graphics Drivers in Windows*

Latest Graphics Driver download: Intel® Arc™ & Iris® Xe Graphics - Windows*

Are there any specific error messages or logs from OBS or other applications that might give more insight into the encoder issue?

To better understand your system's configuration, I kindly request that you download the Intel® System Support Utility for Windows* software. 

You can find the download link here: 

• Intel® System Support Utility for Windows* 
• Here's a quick guide on using the Intel SSU: 

1. Download and launch SSU.exe. 
2. Check the box for "Everything." 
3. Click "Scan." 
4. When the scanning is complete, click "Next."

No only the regular updates from Windows 11 the problem occur when i did the update from  101.6299 to the newer version if i rol back to the drivers 101.6299 the problem is gone.

Now i use the new drivers again 32.0.101.6559 but i must start OBS Studio with admin rights to not having the problem that the QuickSync options are gone.

It is strange that OBS needs admin rights after the last driver update if a rol back to the previous version the problem is gone with no other system changes.

I already try two times to do a clean install of the new drivers the solution with OBS starting as admin a find on the internet and that works for now but program starting as admin is not a very smart solution. 

I must say that I am otherwise very satisfied with the streaming quality of this video card. As an example, I will give you a link to a livestream video of mine just to show how good it works ( https://www.youtube.com/live/ZhnPw8Pa6KU?feature=shared )

I can confirm this issue using driver 32.0.101.6559 on an ARC A770 16GB

This issue also occurred on Handbrake, and not Moonlight/Sunshine, running the applications in admin mode temporarily fixes the issue.

However it requires running the applications every time in admin mode.
