Interested I use virtual desktop for VR (assume that’s what you mean) might give it an uninstall and a test. But I’d rather keep that over Intel AOP!

[Viscerous]

Yes, but you may be able to get away with only uninstalling the display driver, it's only used for additional virtual monitors in VR. I haven't checked if Virtual Desktop complains once you try though.

Thks all for you're help i did remove virtual desktop and everything working now....

[byronhinson]

Reported it to intel and VD. VD dev said they’ll look into it

Mmmm... I just removed "Meta Virtual Desktop" and it display driver. Gonna test by restart the PC. Will report soon.

I hope the SteamVR update don't mess with this too.

EDIT: Confirmed. Now it's working by removing Meta Virtual Desktop. Thanks everybody for the support!.

I managed to make it work by using a different installer of DTT v 11405.42569 for my 13th. I basically reinstalled on top of the same version posted here, no delete or driver cleanup, it had a .exe installer. Now it works; I also believe certain DTT versions are for 12-13th gen Cpus while other Dtt variants are better for 14th.

Intel DTT 9.0.11405.42569 (Ipf driver V1.0.11405.42038) for Windows 10 64-bit and Windows 11 64-bit.

What is GNA driver? Do I really need to instal this driver? Can someone explain please?

[Johnnie123451]

Hey emred,

The Intel GNA driver is for the Intel Gaussian & Neural Accelerator, it is a special purpose hardware on the chip that software can use to efficiently run some computations, namely neural network inference. This is similar to Apple's "neural engine" on their CPUs. GNA can run some simpler neural network models with perfect energy efficiency. You can install it tho.

Also in my experience you have to enable GNA in the BIOS. If not enabled then the driver is not needed;

Advanced | Onboard Devices Configuration | GNA Device | Enabled
Somehow its not by default enabled on my TUF GAMING Z790-PLUS WIFI motherboard.
