For documentation:
I made a successful DSDT override, but failed to find a solution via the following 36 bit compaction. This is due to some language problems in the files (so it applies to non-english users only)
The solution (many thanks again to nando!):
You have to execute EGPU-setup mount in your e-GPU folder and navigate to the resulting v:\config.
There, in the devcon.txt you have to remove the part about PCI Complex (there is only one).
After a reboot, i was able to make a simple 32 bit compaction and voila, it worked.

and then you should see in the sub-menu "dgpu=off" oder does it just freeze?

I do not understand the second part of your sentence after "on", but you can just deactivate it in the menu video card and then try a pci compaction.
-
Is it possible to deactivate your dGPU via BIOS? Do you have Setup 1.3 to deactivate it?
If you don't do it, it won't work I think.

Update: By some miracle, I did a teardown of my expresscard and put it back together and it worked the next day. My egpu turns on fine.
Now for the fun part! I did get the drivers that last supported the Optimus drivers, but the drivers are refusing to install or they come and go. I'm tempted to downgrade to Win 7 to see if it's a driver issue because my iGPU and my eGPU are not getting along.
Thankfully no Error 12. Mostly 28

Hi,
based on my own experience using Win 10, I'd recommend a downgrade from Win 10 to 7 . The automated driver installation of Win 10 screwed up everything for me. Even hiding the drivers with the special tool provided for Win 10 didn't work out well.

Optimus does work as intended, it's just that using the internal LCD takes a large chunk of the precious x1 bandwidth for video display data. Bandwidth sensitive games will then become choppy as you've noted. Decreasing resolution and/or depth will decrease internal LCD bandwidth requirements.
The better solution is to increase bandwidth by using a TB2-16Gbps or TB3-32Gbps eGPU. That's 4 or 8 times more bandwidth respectively than 4Gbps-EC2. Though that requires a replacement notebook & eGPU hardware. It's certainly more dollars than your current x1 eGPU hardware.
The choppiness is only occuring with the new NVIDIA drivers, now I'm using 331.xx and it runs smoothly. However, the general performance with the internal screen is very low.
When I was using my dGPU, the benchmark results were very low (a bit more than 1000 in 3dmark11 compared to 4200 with eGPU), however the gaming results are quite the same as with the eGPU, although all benchmarks indicate that I have 80-90% of the external score. Are the benchmarks that bandwith-unsensitive compared to real games? I thought that CS:GO would be a rather undemanding game, but I had problems in L4D2 and TF2 as well.
Furthermore, I'm having problems with BSOD Nr. 113 and 116 from time to time, but those are only occuring in internal screen mode. I would have expected decreased performance, but not total crashed. Is this a normal behaviour or is something messed up in general with my setup?

After reading some more threads and experimenting with the settings, it seems that my main problem is optimus.
On the external screen, everything runs smooth with high fps, but on the internal screen, no matter if I choose x1 2.0 or 1.1, everything is a mess of graphical glitches and flickering.
The only game that is running is Cs 1.6. In the Nvidia Driver menu, I've set preffered device to NVIDIA, so eGPU should be used right?
Any ideas why my optimus doesn't work as intended (I've also used different driver versions, even back til 341.xx)?

Hello everyone,
first of all, please excuse my English.
My Dell notebook has an integrated Intel HD4000 and a dedicated AMD HD7670m, RAM is 4 Gb. I'm using the PE4l 2.1 adapter and an AMD HD6950 as eGPU. I figured out that I have to use Setup 1.x to disable my dGPU.
Tolud is 2,24Gb and should be fine I think? 256mb space are free after pci compaction, the box goes from yes* to yes after compaction
Here are the steps that I've taken:
- PCI compaction using "ignore dGPU", 3,87 is OK and renders no errors
- Then I disable the dGPU
- Then reboot into Win10 via chainloader
But at this point the screen just goes black, sometimes the fan of the eGPU goes to max speed, sometimes it seems to slow down a bit. I can't even reach the login screen, external display plugged into the eGPU also doesn't show any reaction.
I've also tried to hotplug the eGPU, the screen just goes black and the system crashes.
Is there anything I've forgotten to do? After reading countless threads and guides, I still can't figure out what is wrong.
Thank you in advance!
After reverting back to Win7 and switching to an GTX 470 as eGPU, i finally got everything up and running...
However, even though the GPU should be able to handle Counter-Strike 1.6, I can't seem to get constant 100 fps. When starting CS: GO, there is much stuttering, even in the main menu and graphical errors.
Benchmarking with 3dmark11 works, I get 4200 points, so that should normally be no problem. GPU-Z confirms that x1 2,0 is running. Even switched the driver version back to 347.09, no change.
Do you have any hints or tips why I encounter that massive problems in real games?
Thanks in advance.

See post of Kizwan with the most common corrections. After I had fixed the first error (of 143), all other were resolved as well.
