Help me please

Hi,

 

I would like to run OBS with dGPU ONLY. OBS somehow still uses iGPU even when I do everything in my power to not let it do anything. It makes the system chuggy, and all system animations slow down to what seems like 10fps. (especially switching between different desktops) On a $3000 Dell XPS 9700. 

 

I'm currently attending all my classes from home, and the system really doesn't like to stream the session, record with OBS, and have multiple programs actively used + 3gb worth of MS Edge tabs in the background. I usually have Handbrake running too. I would like to offload more of my computational work to dGPU (rtx 2060max-q), because it's just sitting there doing nothing while iGPU is literally burning. 

 

Any suggestions are appreciated. Take me as a very experienced windows user, so don't shy away from more advanced solutions. 

 

Cheers

Is your encoder set to NVENC? That will make it run on the GPU.

OBS is run on dGPU from the start, and I'm encoding with it. Since display capture doesn't work on dGPU, I have to use app capture or window capture. I use Nvenc, of course. But with all that, somehow iGPU still does all the screen composition crap. And pegs it at 70-90% when I'm also streaming a class session. It's infuriating. I'm not even running the program with it. I swear, these passthrough connections from dGPU through iGPU to the display have to end. I'm so over it.

It's possible that's normal behaviour and you can't do anything about it, but take that with a grain of salt as I don't have a ton of OBS experience.

So you're doing all this just to record the classes you're attending? What software are you using that doesn't have session recording?

What happens if you disable your iGPU?

They don't record it. And even when they do, it's only online for a couple of days, then gets deleted for space preservation.

Our school wasn't prepared for online courses at all. Online classroom is crashing as it is..

There's no direct connection from dGPU to the laptop screen, there would just be no picture. I would need to use a secondary monitor and enable direct passthrough in bios. Which I could do, but I won't. Because then I could just use my desktop PC instead.

I just want to take strain off the iGPU so my desktop environment doesn't completely die.

Just as a side note, is it also chugging when just recording your class instead of blasting it with multiple heavy tasks? Maybe it's just a bit too much for it.

I only use it for Zoom meetings really and on Linux, but perhaps you can try setting OBS to "high performance" in Windows: https://obsproject.com/wiki/Laptop-GPU-Selection-Windows-10
