you wrote in your post, that you had W7. how did the upgrade to W10 work? did you have to make the 1.3 setup new?

im using w7 atm but i want to have W10 for some reasons. 

 

  I did not have to use Setup 1.3 on my Windows 7 system in the first place so I do not know how that will work. But for Windows 10 I did a clean install using the Media creation tool. Though I read that the in place upgrade feature works pretty well.

Just a update to my above report, I tried 361 drivers with an external LCD. To my surprise Starcraft 2 was flickering in the main menu as well, though much less than using the internal LCD. Tomb raider still crashes in the main menu.

At this point, I want to point out that perhaps there might be some issues (hardware or otherwise) with my setup and the above results might not be related to the optimus issues at all. However, all these problems certaintly did not happen with Windows 7 + older drivers.

I tried Nvidia's 361.43 notebook driver. A thing to take note is that the notebook driver and the desktop version of 361.43 have the same filesize and version number. I did not check the files contents to see if they are identical. All tests were done using internal LCD only.

Update: 361.43 drivers whether for desktop or notebook are exactly the same, same file size, same folder structure when extracted

Background:

I am currently on Nvidia 344.75 desktop driver on Windows 10, I find that any newer drivers gave me stuttery performance and flickering in Starcraft 2, WoW and Furmark. This has been happening even when I was on Windows 7, starting with drivers around 347.XX range (can't remember exactly which).

System Specs:

Thinkpad X220 Tablet

i5-2520m

16GB Ram

HD graphics 3000

Geforce GTX 560SE @ PE4L 2.1b running on internal LCD only (1366 x 768)

WIndows 10 64bit

Nvidia notebook driver test:

Unmodded

Surprisingly, the 361.43 notebook driver install without any problem unmodded. The flickering and stuttering only occur when I start a game in Starcraft 2. Tomb raider 2013 crashed while navigating in the main menu.

Modded (with Nando's instruction above)

Since it's a Windows 10 driver, some steps will differ such as "[NVIDIA_SetA_Devices.NTamd64.6.0]" will be "...NTamd64.10.0" instead. For this driver, Starcraft 2 starts flcikering and stuttering even in the main menu. This symptom is similar to some of the newer desktop driver I tried (35X.XX). Was not able to start a game due to the amount of flickering. Tomb Raider 2013 crashed as well. Thus, performance and stablity is worse than the unmodded driver.

In the end I reverted back to driver 344.75. Hope the above info helps anyone who is troubleshooting optimus problems on their systems.

Is anyone experiencing performance issues with NVidia drivers 350.xx series and above? I'm having problems like freezing (even in the menus!) and the next frame loading a few seconds later and stuttering. Thus, I'm currently on 347.09 drivers in Windows 10 where these issues are non-present and my games like StarCraft 2 and Heroes of the storm works perfectly.

Both Windows 7 and Windows 10 exhibits the same behaviour even with the latest Windows 10 NVidia driver. Anybody having similar issues?

Docking and Undocking:

The docking and undocking is easy. But before you do one of the options, you need to power on the eGPU while your laptop is booting and the windows dots are merging (in case you haven't disabled the dGPU). If successful and set the external monitor as your main display, you can undock it by going to "safely remove hardware and eject media" icon that's hidden in Windows taskbar, and then select eject video controller. To dock it again, simply connect the eGPU to the laptop.

Thanks!. This is a little OT but I did not know you could freely plug in and out like this ones the laptop has booted up with the eGPU. What I did before was to completely shut down my laptop before plugging in or out, much more cumbersome.

So I decided to redo my enclosure for my setup. By using 3 baskets from Daiso, I ended up with this:

Quite snug and compact. Up next: will mount a thin cover on the 3 stakes.

Did a eGPU a while back, here are my specs and results. Everything was pretty much plug and play with the X220t, easy to setup.
