[BUG] Displaylink 7.4 M2 - Directx DDI issue

[otyg]

The displaylink driver 7.4 M2 causes the GPU / DirectX DDI version to downgrade from 11 to 10.1 , as you might of guessed this will break DirectX 11 detection in some games / programs
(I assume this is the main culprit 'bug' that triggered the issues other people are having with this driver, that never had problems before)

Just few affected games I have tested are
1. Tombraider 2013 (can no longer select / enable directx 11 features.)
2. Crysis 3
(I'm sure there are many more)

I have a Nvidia Geforce 560 TI gtx video card with the 331.82 drivers. (latest at the time of this post)
Displaylink device is the Sabrent USB-HRHD Usb 2.0
Windows 7 64bit Sp1 + all updates.

7.4 M2 (DDI 10.1 (should be 11 for a directx 11 supported video-card), broken WHQL detection)



----Here is an older driver screen shot, and also how I know this bug is related to the Displaylink driver-------


Old Displaylink driver 7.3. M1, 7.4 M0 (working correctly, DDI 11)

Hi,

Can you attach the logs from this tool with 7.4 M2 installed?

Sorry, but this is a bigsh***.
The Current actual Link Manager degrades DX11 to DX10.1. All DX11 Games and Applications are not Working.

I have for four days looked and searched in the Net and in my System where is the error. Why i can't Play DX11 Games.
i have postet in various Forums (Technet/AMD/PCGH).

I think it cannot be on 32bit runs Feature Level dx10.1 with Max Shader 4.x and on 64Bit DX11 with Shader 5.x.
I have a XFX 7850 Black Edition with DirectX 11.1 and use the USB 2.0 Link Manager with a Third Monitor.
I do a fresh install look in any dammned Windows Update and Install and run DXDiag 32bit and 64bit. Alls Fine, DX11 is here.

Now i Install Displaylink manager the comes from Windows Update and boom.. now i have dx10.1.

So i have now the actual Version deinstalled and runs with version 7.3. It does'nt degrades to DX10.1

Important and Prio One: This must be Quickly Fixed.
Best try and Research in development. Place a DX11 Card in a PC Maschine

PS: Sorry for the Hard words but i'm very stinky.........yes i'm German User with terrible English

Hi,

This issue has been raised internally - I'm seeing the same thing.

Thanks,

Lockheed Martin Prepare3D also has a problem with it.
