Arc has issues with everything that uses Hardware acceleration

[Saveno]

I really like the Arc, but ever since i bought one earlier this year i constantly have problems with everything that uses Hardware acceleration.

For example:

When i use any browser and watch a video, my monitor turns black for a second from time to time. Sometimes it also happens that videos start sliding from left to right across the screen (next time it happens i will try to record it).

Same issue with Steam, Discord and GamePass, i have to disable Hardware acceleration there as well.

And rendering in After Effects via GPU acceleration often results in the program crashing and sometimes it even freezes my whole PC. 

Games on the other hand all work fine and don't cause any problems. The problem seems to be related to playing videos in any program with hardware acceleration.

Some more info

I have reinstalled Windows multiple times ever since.

Already used DDU a dozen times.

ReBar is of course enabled and functions.

Happens when screen is connected via HDMI or DisplayPort

When this happens, i often notice that Desktop Windows Manager suddenly starts taking a **bleep**ton of Ram and has to be restarted.

I used OCCT to check my CPU, RAM, GPU + VRAM and i did not get a single error.

When i tried to find a solution online, i also often read that it got fixed after people disabled hardware-accelerated GPU scheduling and that this issue also seems to happen on other GPUs and not just Intel ones. There are reddit threads for example that report the same problem on AMD and Nvidia cards and that the problem was always the Driver.

I've just given up tbh. No matter what issue you report many others have as well Intel is just like "Sorry can't reproduce bye".

I don't remember the last time i've regret buying something "expensive" that much. Will never get Intel Hardware again for sure.

I had a similar if not same issue, I run dual screens one monitor and one TV display connected to my intel 125h APU with integrated arc graphics.

The issue usually pops up with Google chrome browser and  youtube flashing black for a split second when scrolling up and down on Youtube on my TV 2nd display (1st monitor is fine)

I spent 1 day checking this out, the easiest and quickest fix for me was to use firefox instead of Chrome. Firefox browser gpu acceleration is working fine, Chrome, Edge and Brave is not.

I was not happy with this so tried using DDU found here

and booted into safe mode under windows 11, I removed the intel arch/graphic drivers fully and rebooted PC and re-downloaded latest Arc intel drivers and re-installed the latest drivers and rebooted again, this fixed my chrome and youtube issue 100% since I tested it several times.

I noticed previously in my intel arc control panel it mentioned variable refresh rate was set to OFF, setting it to on gave me an error message saying it was not possible to enable variable refresh mode. But doing the DDU in safe mode and reloading fresh now it auto sets variable refresh rate to ON. This might be important for others to check out.

I also think newer drivers or maybe more older drivers are worth a shot.

I have the same issue with NUC12 Enthusiast ARC 770M since day 1. Doesn't matter the driver version. I thought It happened more frequently when tv was connected via HDMI (main monitor is on DP). The truth is It never stopped happening. Intel offers no solution. I would send the pc to support though I use it for work and don't know how long it would take to get it back.

Does it happen in firefox browser?  did you disable gpu acceleration in chrome or firefox also?

These are the 2 "quick" fixes I found at least, but the better option was a clean windows 11 install + fresh arc intel drivers.

I have had no issues for past 2 weeks with YT and happy with the mini PC.

Haven't tried in other browsers, but with Opera disabling GPU acceleration worked ok.

The fresh install though. I'd hope that works but I have dual boot with two different installations, and both have these issues.

Anyway thanks for sharing. And I hope your system remains stable.

From the beginning the Intel Nuc 12 Extreme has been an issue.  I have run into many problems with the ARC Graphics...  the 10gb ethernet..  (not just one unit.. I have two.. both have the issue)..  Problems with the thunderbolt link..   Issues upgrading the BIOS..

The other issue is the "backdoor" access to the nuc.  The poorly documented ethernet access to the bios which can take over a system remotely...

Now.. transfering the Intel NUS over to ASUS...  Support was marginal before..  now..  I feel I have been let down!

I am very disappointed with Intel...
