[Sticky] [GUIDE] accelerated internal LCD on non-Optimus systems in Windows and MacOS
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?
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.
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.
- I have latest windows and
adt r43sl I disabled dgpu and pcie x16 in device manager and I set high performance gpu gtx 1060 but games and screen still accelerated by cpu if I use hdmi dummy I get 120 fps cap limit I dont get it whats problem maybe amd gpu will be fine for internal screen because I cant move my monitor with my notebook all time.
I wonder if I have found such a solution
This video would also be the delay I wondered the screen with the player mirrored
sorry for my bad english
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
