GTX 960m

[Umeshwarnath]

Hey peeps,

So I am having trouble with my laptop, not being able to watch 4k videos.(i7 4710hq , 960m 4g, 8gb ram). For some reason the thing tries to use the cpu to play the videos.

So I changed the power options on intel properties to high performance, changed nvidia settings to use dedicated nvidia gpu but to no avail. Normally on my desktop i see the video being played on the 1070 (in the task manager under the video decode box) but on the laptop it constantly tries to play it on the cpu and fails miserably.

Even 1080p videos play on the cpu and i can hear all sorts of pops and crackles in the audio and lost frames too.

But games run just fine( fine for a 960m that is).

All drivers are up to date. Laptop plugged into power.

 

PLEASE HELP. I am going to punch a hole in the screen very soon.

 

Edit: Since posting i tried playing Planetside 2(dx11) and i can see the 960m at 80% usage and the intel hd 4600 at about 70 percent usage. Nvidia reporting 50fps but its unplayable due to stuttering! at this point i have no idea what is going on.

check if hardware acceleration is disabled (it should be on) in the browser settings

You need to force it to use GPU in the Nvidia settings.

[Umeshwarnath]

Hardware acceleration on, global nvidia settings set to use dedicated high performance nvidi gpu.

What browser? Assuming you're meaning Youtube.

What video player? Assuming you're meaning downloaded content.

[Umeshwarnath]

Firefox (same issue on all 3 browsers ) 

VLC (same issue on windows default player)

The edit of the original post has another issue stated now. Planetside 2 is unplayable. The last time I played it ... a year ago... it wasn't so bad. Recently it had received a dx11 update (from 9) but that couldn't have possibly made it so much worse. Unplayable at 50fps

Can you turn off the IGPU in BIOS and leave ONLY the 960M turned on? If so, do that, see how it performs. Have you done a DDU to wipe all the old drivers then reinstalled the drivers? Every now and then updating over old drivers will do weird stuff.

i reinstalled windows after a full c drive format and got all the laterst drivers. the problem remains. even 1080p videos are dropping frames/ crackling audio.

The problem is with it trying to use the onboard graphics when it shouldnt be.

i dont see an option in the bios to turn off onboard graphics(although there is an option to turn the 960m off)

And i cannot afford to buy a new laptop

anyone know how to disable onboard graphics?

did you try safe mode?

The Intel HD4600 graphics should NOT have a hard time playing back 1080P video on Youtube or with VLC, my laptop has an i5 580M which has Intel HD graphics (Westmere) which is substantially weaker than your HD 4600 and it has NO problem with 1080P 30FPS video playback, it does choke on 1080P 60 Youtube some though. I think you have a problem beyond graphics switching.

@starcoaster i have already reinstalled win 10. It didnt help. Still having the same issue. do you still suggest purging drivers separately(which i had done before reinstall and it didnt help).

 

How do i nuke the intel drivers? what do you mean by that?

 

[Bitter]

If you run a different operating system, like a linux distro, does it do the same thing?

[Umeshwarnath]

@Bitter I dont known. Haven't tried that yet. 

@starcoaster didnt know laptops had a bios battery. I will find it and remove the thing and let you know if it changes anything.

Don't use the newest driver on the 960m, try and roll it back to an older driver, should be able to find it on the nvidia website. Rather it will work or not I'm not sure, but it's worth a try, make sure to DDU it first, and don't reboot it until you installed the older driver or windows may install one automatically on a reboot. Might try the same thing on the Intel graphics as well. Hope this helps.

Ok guys, will try this and update soon! Thanks.
