How to disable optimus on dell xps 15 completely?

Hey.

How to disable optimus on dell xps 15 completely?

I just want to use Nvidia all the time, for everything, how do I disable optimus so it does not use Intel graphics ever?

Thanks.

 

You can't.

 

Yup, go into the optimus settings and set it to use just the nVidia card.

 

You cant. All video signals go through the intel IGP. It's impossible to switch it off.

 

I never had problem with optimous, it seems to work good.

 

Not really sure why you'd want to do this unless you're having problems. This technology was designed for a reason, gpu power when you need it, battery life when you don't. It should switch automatically when it needs to without you ever knowing and work flawlessly. If it's not, less us know and maybe we can help you.

 

The only problem im having is that when i run the Windows Experience Index I only get a 4.8 for desktop graphics performance but all my other scores are 5.9 and above. I just want to run it with the nvidia card so that my score will be better haha. Ive tried playing with the graphics settings and changing it to use nvidia all the time but it still gave me the same score.

 

if u really want the WEI scores, just hook up a monitor to your laptop and then run it. it will use the nvidia card the aero score.

 

i think MS should upgrade thier way of analysing the graphics performance in system which uses technology like optimus to give us the accurate result...

anyway the idea you gave is really a good one...

 

Is there any way to make it so that running on battery the Optimus chooses the Intel Card to play videos rather than the NVIDIA to save battery?

 

mystycs: There's no way to do that in the current version, though in theory there's no reason they couldn't add that to a future driver. However, I haven't had any issues with setting video software to always play using the IGP--it's plenty powerful enough to HD video.

 

I was able to do it by using a non-optimus, non-dell driver that was posted here a month ago (266 or 267 series driver). That driver basically eliminated the optimus menu and all apps that launched saw the 525M as the main card instead of the Intel HD graphics.

 

Ah okay i guess its the only way, but doesnt using the IGP have less quality than using the NVIDIA for video quality for example 1080p or 720p mkv files?

 

There is no such thing as video quality, it plays smooth, or it doesn't. Even the HD4200 can handle smooth 1080p/60 playback.

 

The only thing you'd be missing out on are just some of the special processing that the NVIDIA card can do: Edge enhancement, noise reduction, deinterlacing. However, the IGP has its own enhancements that pretty much replicate the NVIDIA ones: Noise reduction, sharpness, film mode, skin tone enhancement, adaptive contrast enhancement.

 

Any news on this?

Is it still not possible?

 

You can set which card to ALWAYS use which is as close as it will EVER get. Go into the Nvidia Control Panel, under 3d settings, and choose system-wide GPU to be whichever you want.

 

I don't need the nvidia chip most of the time as my work is mostly office. So I have set the optimus to use the IGP all the time and I connect my external monitor using mini displayport which also bypasses nvidia chip (not the case if you use hdmi). Works very well...

 

Why would you want to is the real question?! The optimus does a very good of providing power on demand and thus great battery life.

 

Well that's my feeling, but not all are like that, and that's fine. There is a way to change it for those that do. I just leave mine on auto-select and put any games that detect incorrectly (only one or two so far) on the NVidia. Thus I rarely run on the NVidia, usually on Intel.

 

My laptop is on battery most of the time, as I have another laptop for carry around, so thats why dont really need Intel.

 

Errr? You mean always on AC?

It still generates less heat when running on Intel, a consideration when on AC and don't need the GPU. But hey, it's your system, the option is there for that reason.

 

Bump.

Ok I have a problem.
My system configs are Windows 7, i5, 4GB DDR3, 500 HDD & 1GB 425m NVIDIA with Optimus, but i'm still having problems with the graphics of quite a lot games.

My friends with half my config are playing certain games on MAX settings, while I can't play those games beyond Low settings.
I have put the Nvidia card as default.

Now, alos whenevr I try to check whether a game woudl run on my laptop vai Canyourunit dot com, its gives a thumbs up for everythin except for Video card where it displays Intel Graphic card even though my default is Nvidia.

What do i do now?
