G750JZ w/ Nvidia 880M want to disable Optimus and run only 880M card not Intel

[Art3mis777]

Ok, so I was running the XTU stuff and I was getting weird numbers. First, I ran the stress test for around 10 minutes and it reported back that the CPU got up to 87-88C. Then, I went on a little later and ran the Prime95 Benchmark included in the software, got 711 marks, and racked up a max temp of 90C. Is something wrong with the laptop? During regular gaming and stuff like that, I'm don't really ever go above 70-75C (GPU usually gets to around 70C too). I got it from Prostar and they did some customization work on it and I just wanted to know if it is too hot or something. Thanks! And also, I was wondering about this Optimus stuff, and after searching around, I settled on just designating certain programs for use by only the Nvidia GPU. This should get around the whole Optimus BS and I haven't seen it get overruled yet. You can do it in the Nvidia control panel.

The problem is the desktop wants to use the Intel GPU, and when you have multiple programs running, some do and some don't use the Nvidia GPU - so there is switching going on all the time - at least that is how it was on other laptops with Optimus I have used - my G750JH doesn't have optimus.

I am/was planning on getting a JZ, so I am concerned about the day to day use of multiple programs running at the same time and how they trip the Nvidia processing on and off as I multitask.

There doesn't seem to be a way, as per this thread title, to disable Optimus / Intel GPU completely, and only use the Nvidia GPU - and yes I do know that all the display outputs come through the Intel GPU - worst idea ever - so you can't completely disable the Intel connection with the video display - I just want to keep the 3D processing and acceleration to go only through the Nvidia. We don't seem to be able to do that.

And, as Windows desktop does more than more 3D assist processing to do it's work, I am concerned about the switching back and forth and how it affects performance - glitches - lags - dropouts - etc.

Hmmm, well, I am completely new to all of this (bought my JS only a couple weeks ago) and as far as I've seen, everything has worked perfectly. However, I do understand what you're talking about because I can just imagine, like, rendering a video and using the Nvidia GPU and then opening a youtube video to pass the time and the Intel card comes on. With my super-limited knowledge, I think that it'll just be up to Intel or Asus to fiddle with the programming to have the computer prefer the Nvidia GPU for everything, but still route the display through the Intel GPU since that's the one connected to the display. It would be even cooler if you could run both at the same time so that you could be running something like Affter effects or Solidworks on the Nvidia, and then be watching a youtube video or browsing at the same time with no interuption of the speed in either GPU. That may be wishful thinking though.

Art3mis777, all good thoughts

We are also all relying on Intel/Nvidia/Asus to get things running smoothly, and it looks like for the most part it does. Once you figure out how to set an app to Nvidia GPU only, and how to recognize when to do that, it is smooth sailing.

It would be nice to have a switch that says Nvidia only, Intel only, or "please muck around behind my back and then default to Intel Power Saving even while I am on AC power" - unfortunately only the 3rd option is implemented.

Why would we care to use Intel GPU on AC Power, ever? Why add heat to the CPU, and idle the most expensive item in our laptop - the exact item I spent so much money to get - the item that provides the best performance. Why???

I should mention I waiting for the call for my JZ to replace my JH

use this
https://app.box.com/shared/v7jpoateoq

it's a program called powermizer switch. on systems that improperly switch, this can be used to disable the powermizer feature. reboot after applying. when installing new drivers the switch will reset to default. after installing new drivers, run the program and again disable powermizer.

it must be run as administrator.

hope this helps.

I believe the nVidia driver settings have the ability to add a right-click option to the menu to say: run with Intel, run with nVidia.

I can't make Movie Maker use NVIDIA GTX 880M, it is impossible, it is locked on integrated.

Master Po, yup, Movie Maker has problems when set to Nvidia as preferred, you need to keep it on Intel Preferred.

you can try my steps here. I think somehow its related :

Jukkaz, that is a good tip, Master Po give that a shot.

What I have seen so far with Optimus before now is that it won't work on Nvidia, but if Jukkaz's tweak works, it would be good to know.
