Is there anything you need to do, to enable Optimus? Or just boot with the eGPU and start the game?!

According to release highlights they added: Beta support on GeForce GTX GPUs for external graphics over Thunderbolt 3

 

In the past Optimus could be enabled using certain changes in the INF (and probably still can.) Ill be interested to see if there are any obvious changes in these to allow for external graphics (Optimus) support.

 

Edit: Looks like we do indeed have some newness.. 'Surprise Removal' sounds like eGPU support to me. :)

Can confirm Optimus now works on my mid-2014 Macbook Pro 15 with Iris only graphics using driver version 361.75

can i use optimus on egpu without disabling dgpu in windows 10? 

I am not too sure on that. Someone should try with the latest drivers on a dgpu model.

I can confirm it works. Well at least we can use the eGPU to power on the internal screen and we don't need setup1x to disable the dGPU before booting into Windows.

I've just tested it in my Asus G46VW using EXP GDC Beast mPCIe.

I can have the 660m and 750 2GB on at the same time with drivers 361.82. I was even able to have version 361.75 in the GTX660m while at the same time version 361.82 in the GTX750 2GB. In order to "force" the GTX 750 to power the laptops internal screen all I needed was to disable the 660m in the device manager and restart the laptop. Not restarting would the mean that only the HD4000 would power the laptops internal screen.

In my opinion this is a huge improvement compared to what we had before, specially in Windows 10. But on the other hand this should be like this since 2012... I guess its better late then never :)

If your machine only has a dGPU built in, will disabling the dGPU (no iGPU) after having the eGPU up and running route the output to the internal display if you turn on Optimus?

As far as I know in order to have optimus enabled, one of the requirements is to have a system with the Intel iGPU enabled.

Update

I tried the same with my GTX680 4GB, but I was unable to make it work with optimus. Either something went wrong, or NVIDIA is not supporting older generation cards. I hope something went wrong because a GTX680 4GB is still a very capable graphics card. And as we know a GTX770 is a GTX680 with a bit faster Ram, so there is no technical reason to limit its use, unless for comercial reasons....

I need to test the GTX680 4GB connected to my Dell E6430 (iGPU only model) with Windows 10 and this new NVIDIA drivers. Update! I tested it and as I thought it doesn't work. I wonder if it was intensional or not, if it wasn't maybe its just a matter of modding the drivers. I have no problems enabling optimus using the same hardware with Windows 8.1 and the same version of the NVIDIA drivers but for windows 8.1.

Made a total reset of my MacBook to test Windows 10 today.

I have eGPU performance on:

- external display

- internal display without external display

- internal display with external display connected and internal is main desktop

 

Had some trouble with the driver in the beginning but after some reboots and the installation of the latest driver it all worked great!

Can anyone else confirm a 60FPS cap on the internal display? No matter what settings I choose, I can't exceed 60FPS.

Small offtopic

My 20€ eGPU adapter. Just a mPCIe to PCIe converter and a mPCIe extender. Same performance and without the rigid and bulky hdmi cable.

In witch games? Some games cap the FPS at 60, some even 30..

FPS capped at 60. But only in directx 11 games or benchmarks, directx 9 runs normally.

Is there a way to handle Optimus in any way?

I sometimes boot into Windows and my internal MB display is turned off, because the Intel Iris GPU isn't recognized. Without the Iris GPU I have different Nvidia options, that are not available when the Intel Iris is available as well.

E.g. without the Intel Iris I can set and use Nvidia DSR (downsampling) in games to play in 4k on a full HD display. As soon as the Intel Iris is installed, I don't have that option anymore...

Good Afternoon, 

 

I have just installed the latests Nvidia Drivers on my MBPR ( Iris Pro + 750m ) in Windows 10  and have my GTX 750ti recognised in device manager as well as some of the options in Nvidia Control Panel. It does not give me an option, however, to enable a total switch to the GTX 750ti for applications and games.

 

Is there an additional step I must undertake ( presumable to enable optimus and allow a total switch ? ) I have tried disabling the gt750m however this then prevents nvidia control panel from recognising the gtx750ti. 

 

Many thanks for any response

Will follow this thread acordingly, planning to use a gtx 970 on pair of the inner k1100m for CUDA applications, being able to set the eGPU without the setup 1.x could be a great benefit from this new driver on W10

Can we use TB3 on non-Macbook? And run the internal display, all results and previously established functionality being equal?

 

Looking into going the TB3-laptop route if a dock is ~150 or 180usd.. Maybe 200 consideration. : ) These things need to go mainstream and get cheap(er), at some point.

 

Can we drive say, external 5kCinema or 8k (these things are getting, and going to be sanely priced/on market, surely by Tokyo 2020 Olympics, if not mid-17'-early 2018) to TB3 e-GPU from a laptop (Say 6700hq/950m) wherein each i-gpu/d-gpu do not, nominally 'support' above 4k,

though e-GPU will?

      I have always been a big fan of Windows 7. I have 4 Media PCs throughout my house and a laptop. I have recently updated some of them to Windows 10 Pro. I have tried everything to get them talking on my LAN. I cannot share files anymore. They all ping, but are missing in the network folder. Thank God for Plex. Any advice?

      Hi guys,
       
      I'm sorry for making another thread just for this but I really wanted to pick your brains on this!
       
      I have an m15x with a 770m running windows 7 and everything works. Rock. Solid. I'm pretty happy with it. Since windows 7 is on it's way out, I would like to upgrade to windows 10. Now I've looked into it before and had a really hard time getting the 770m to behave nicely and had all these issues with green/yellow/pink screens and I remember it being a miracle I got it to work on 7 as good as it does.
       
      My question is how well does the 970m install vs the 770m - particularly on windows 10? I would buy it in a heartbeat if it makes the install less tedious with the colored screens and all that. Especially if all the functions work on it! I have been searching the internet and I cannot find nearly as many problems with the 970m as I could with the 770m, or am I just  not looking in the right places?
       
      Thanks a million!

      Hello. I'm currently running windows 10 on bios version 1.00 and want to upgrade to 1.03 but cannot boot Ms dos flash in uefi. There is no option to enable Legacy mode and the option to disable uefi in bios is greed out. When I try booting from flash in bios, it shows black screen and returns back to bios screen. My rig is a p157sm. Any help will be appreciated as I'm looking to install prema bios mod.

      Hello
       
      My M18XR2 was working on Windows 10 with a 880M.
      Last week, I reinstalled my system, and I couldn't get nvidia driver working...
      I took the last installed modified driver, and even downloaded latest version, modified it again, nothing to do, I have same error : nvidia installation failed. 
      I only install the graphic driver too, it fail. The screen goes black, then light again, and it fail...
      Do someone have an idea how to fix this probleme ? 
      Thank you

      Hi all. I was wondering if anyone had ever figured out if windows 10 will work with the GTX 770m on the M15x (bios A09). I've found a few forum posts about it and they all end up off topic. Ive tried a few different driver versions but every single one ends up green/pink/white screening when I enable the IDT sound device in device manager and through driver setup. It is stable if I don't have the device enabled. Anyone have any advice?
