Question

Lightroom always using / activating Nvidia GPU (same goes for LR CC and PS CC)

Hi guys,

I have a rather curious issue with LR. I own a Lenovo Yoga 730, which is equipped with nvidia optimus to allow switchable graphics between the integrated Intel UHD 620 and dedicated GTX 1050.

For Battery-saving reasons, I would like to limit LR to the integrated GPU when on the go, however it always seems to activate the nvidia GPU, regardless of the settings. What I mean by that is, that it still seems to activate the nvidia gpu, even though I set the integrated Intel GPU as preffered in the nvidia and windows settings...

And that is, even though LR correctly seems to be using the Intel GPU for acceleration..!

Also when completely disabling the GPU Acceleration, it still activates the dedicated GPU, completely crushing battery life...

Any ideas?

Also be aware that your Optimus software allows for specific settings for specific applications, is Lightroom setup for using the NVIDIA instead of the INTEL, if you are setting a general setting and not looking for a Lightroom specific setting, the software may not be doing what you think it is doing

Thanks for your replies.

I checked and updated all the updatable drivers. Nvidia just released their "Creator Ready"-Driver Package, so I went with that. Other than that I'm running Windows 10 Build 1809 and all of the newest drivers...

Only the Intel DCH Drivers are not the newest ones from Intel (6557) but hte newest ones from Lenovo (6227); can't install the intel drivers because they need to be validated by Lenovo first apparently.

So, all said and done, I still have the same issue.

I looked at MSI Afterburner while opening Lightroom; it seems that Lightroom uses the dedicated GPU ONLY for rendering the Lightroom Window (using D3D 12); checking the accelerated effects (e.g. Radial Filter); I noticed that the dedicated GPU is not used and in fact the Intel GPU struggles a bit with the effect. However, the dedicated GPU still has to render the finished Window and that is going to beat down Battery-life.

Can anyone else confirm this behaviour with Optimus-enabled Laptops?

Actually, you may have to bring up the OS control panel, then get into the device manager, scroll down to the graphics, or perhaps display, and turn one off, followed by a reboot. Not what you are hoping for

however now that I think of it first check NVIDIA for a driver update, AND a utility software update. Updates to the OS, including security patches may have caused issues. (Incidentally see this: Utilizing the NVIDIA GeForce Graphics of your Legion Y530 - Lenovo Community )

ohh, returning to paragraph one, check this out: How to configure switchable graphics on idea/Lenovo laptops - US Make sure the device manager info is correct.

The 'Use Graphic Processor' checkbox enables/disables GPU 'acceleration' features not the GPU itself. It's the OS that determines whether the GPU is enabled in lieu of the integrated GPU.

Right, but why is it that only Adobe Products seem to "ignore" my settings in the Nvidia Control Panel / Windows Display Settings? (Or at least partly ignore them)

It's really a shame that the gpu is woken and not left completely deactivated (I mean, windows can be rendered on the UHD 620 after all)... This kind of defeats the purpose of having switchable graphics.
