Hello Guys i need help with my eGPU
I newly installed windows 10 and when i want to play a game on internal monitor (notebook) then its working only on iGPU
not eGPU and i want to be able to play games on my eGPU (GTX 760)

what version of windows are you using?

You're kidding, right?

ThinkPad X230t, i7-3520M @ 2.9 GHz, Windows 7
EVGA GTX 1070 Hybrid, 2113 MHz @ 1043 mV
x1.2Opt, PE4C V3.0, 4Gbps-EC2

The headless ghost method still works on 2018 15" Macs. However, I get INSANE stuttering, even when locked at 60 fps. Is there a solution?

My Setup:
Acer Aspire [email protected]/4GB Ram/SSD/dgpu: nVidia Go 7600 256Mb ~ egpu: nVidia GTS 450 1024Mb (EXP GDC Express Card)
Windows 10 Pro 1809 x64 with Last Updates
Drivers from Windows Update 307.68 last one which work with dGPU - Geforce 7600go & eGPU - GTS 450 without annoying nvlddmkm.sys BSOD at last.
Graphics settings from Internal Desktop
Graphics settings from External Desktop

I don't have iGPU at system only dGPU. Disabling PCI-Bridge of Internal dGPU switch my screen to Standart Microsoft Adapter with Low Resolution and begin to see at Graphics Settings GTS 450 like High Graphics GPU, but switching don't work anyway.

When I use Dummy DVI or External monitor I can't get Duplicate screen also. So work only trick with Expand Workspace and DualMonitors soft with hotkey which grab active window to another display. Only windowed of course.

Nvidia Panel

Maybe some registry tweak possible forcing High Graphics eGPU and Windows Graphics Settings? any idea will appreciated.

P.S.>Very interesting remark. Games which use Unity 3D engine can work at internal notebook screen fullscreen with egpu  accelerated. Like Gwent and Hearthstone. I don't now how they do it but if we fugure it out it very help.

Sorry for bad english anyway.

Systems without an Intel HD iGPU do not get Optimus accelerated internal LCD mode in Windows. They however do allow *windowed* apps to be started on an external LCD and then dragged to the internal LCD.

Figured I'd point out that if I use extend and drag a window from an external monitor to the internal one there is a dramatic loss in performance (like 50% from using duplicate and running it on the internal display). I'm using an RX 480 via Expresscard 2.0, with the dGPU being a quadro K3000M.  I used 3dmark's Firestrike GT1 for testing:

RX-480 w/ external monitor: 62 fps

RX-480 windowed dragging it onto internal (extend): 13 fps

K3000M internal: 9 fps

RX 480 duplicating external and internal (duplicate): 31 fps

Dell Precision M6700 + RX Vega 64(EXP GDC @ 4Gbps Expresscard) STILL HAVING RANDOM DISCONNECTS ON GEN2!

Hello all,

I know in previous years that it was a considerably difficult task to pipe back to a laptop/internal monitor, especially when dealing with AMD cards. has this changed at all in recent years? Are AMD cards (opposed to Nvidea) viable for this now? Moreover, are there any extra intricacies when dealing with M.2 connectors as would need to be utilized in my case?
