[intel] iris xe - directx 12 not supported on your system

[slim onyx]

Hi. Can you provide any recommendations with this issue?

Intel Iris XE
(Intel 1355U)
Windows 11 22h2 (22621) • updates installed

Latest Driver Version installed. (32.0.101.7080)
Shaders Model version - 6.6
Everything looks good.
But game don't starting.

(directx 12 not supported on your system)

I believe Aion 2 doesn't run on DirectX 11

[slim onyx]

dxdiag

[proper peak]

Game requires directx 12_2
Your GPU driver doesn't support it

[proper peak]

Sadly the only way for you to play aion2 is on Linux #1439671523387375796 message windows sucks

Hi. I don't find any restrictions for dx12 ultimate support only. (12_2)
Also I have 1650 S Desktop GPU without dx 12.2 support and everything works great.
So, I think it's not true about 12_2 only support.

But anyway, I'm glad that Linux community has so significant progress in this direction. Hopefully more developers will be brought into this process.

Thanks for replying 💜

Also I find that new version of UE5 required Shaders Model version 6.
(With the same error message)
But here intel declared Shader Model version 6.6 for iris xe.

You gpu works with D11, and Aion2 UE5 requires D12...

Try with Linux S.O, maybe you get some lucky

[proper peak]

Because the GTX 1650 Nvidia Driver supports directx 12_2
Even if the card doesn't

Same issue here
Any solution?
DX12 runs perfectly fine for Throne and Liberty and the other games
And here I have exact same error

[proper peak]

Windows build version?
GPU/driver?

[slim onyx]

Can you make screenshots dxdiag for first two pages? (Or export)

[slim onyx]

And need debug.log if you can.
Probably in C:\Program Files (x86)\NCSOFT\Purple\2.25.1117.3\purple-zone\cefweb

I use search in Purple folder.

So I’ve tested many things and I’ve came to a conclusion that the Intel GPU is blacklisted on a launcher side
It doesn’t even try to run it with DX12
What I did : ran the test of pc specs inside the launcher for Aion
Ram and CPU are fine and marked as “Normal”
As for GPU “test is unavailable”
Same as a guy above I have Intel
Next step ive checked all the drivers update and everything is up to date
I also checked the DX and it’s not only listed as a working but also I’ve played a game for a year with DX12 on and it worked just fine
After that I did a few other attempts
created a custom shortcut with -dx11 added to the target.
Purple still forced DX12
Edited in Win 64 folder named d3d12core.dll , adding bak.
Purple still blocked the launch before the game even opened
Other games, which are more heavy are running perfectly fine with DX12

The issue seems to be in a fact that a launch happens on a Purple launcher and it whitelisted only AMD/Nvidia and no command line arguments or exe runs can bypass that

[slim onyx]

Can you post system information ? What printed in debug files?

[lusty solstice]

Illl try later
I gave up and installed on iPhone while waiting for NC to fix it maybe , since it’s not my system issue clearly and only a self created issuer of a Purple

[slim onyx]

You use WDDM 3.2? Windows version?

[lusty solstice]

im using windows 11

[lusty solstice]

also yes i do

the laucher isnt actually checking dx12 features

on dx diag everything supports dx12. purple is blocking intel. dev team needs to update the gpu detection logic to fix this issue

[slim onyx]

I can not imagine that they blocked all intel's gpu.

But situation is strange, i agree

[slim onyx]

What version?

[lusty solstice]

i think maybe a specific ones idk. i didnt have any issues with throne and liberty and i believe it might have even higher requirements

[lusty solstice]

Windows 11 Home Single Language 25H2

You will have the same error in recent games which use the same UE5 RT under directx 12_2. The only way is to switch API completely because Intel drivers can't run such features yet

[golden vale]

force the game to run in dirext x 11

Open your Windows Run box by pressing Win + R.

Type in: %LOCALAPPDATA% and hit Enter.

In the folder that opens, look for a folder named:

Aion2 (most likely)

AION2 > Saved > Config > Windows

Once you find the correct folder, look inside for a Saved folder, then a Config folder, and finally the Windows or WindowsClient folder.

Look for a file named GameUserSettings.ini or Engine.ini.

Your Next Step Here:

Open the configuration file (e.g., GameUserSettings.ini) with Notepad.

Search for terms like DirectX, DX12, or RHI.

If you find an entry that forces the rendering API (e.g., PreferredGraphicsAPI=DX12), try changing the value to DX11.

Save the file and try launching the game normally.

if this doesnt work

Find the main game executable (the file that actually runs the game, usually the largest .exe file).

Create a desktop shortcut to that executable.

Right-click the shortcut and select Properties.

In the Target field, add a space and then the DX11 command:

"C:\...\Aion2.exe" -dx11

Try launching the game using this modified shortcut.

[slim onyx]

The thing is. Aion2 is launching with Purple. And another way don't run.
So option with new shortcuts looks unusable.

Need to check first one.

[lusty solstice]

yeah this doesnt work

[brave arrow]

gaming on the intel iris xe is not good at all. the only solution i see is to upgrade.
