    Lightroom CC not recognizing graphics card, Nvidia 960M?

    evan7981

      Hi,

       

      I recently got a 4k laptop to run lightroom. However, it's been awfully slow and laggy in certain areas (brush tool, full screen previews). Obviously, 4k display requires high specs but lightroom is only recognizing my Intel Graphics 4600 and not my Nvidia gefre GTX 960M which would I'm assuming would make the performance run much smoother.

       

      I get the error "Graphics processor acceleration has been disabled due to errors"

       

      Does anybody have any suggestions or help to offer?

       

      I will be returning this laptop in exchange for a non-4k if I can't use lightroom properly without frustrating lag

       

      Thank you!

          Try searching the site for the error - you'll find lots of material.

           

          But the short answer is - the card doesn't meet Lr's minimum spec.

            So you are using a Mac or a Windows PC?

             

            If a Mac they are notorious for not using the add-on, discrete, graphic card until you actually open a program that can and does want to use it.

             

            But in the end the GPU feature currently being used in LR isn't really ready for prime time and in 99% of the installs it is better to just turn it completely off.

              One thing to know about the graphics card acceleration is that it actually slows down the brush tool by quite a bit if it is working. So be careful what you wish for. That said, you should probably go into your graphics setup in windows (this sounds like a windows machine) and turn off the automatic switching between builtin graphics and discrete graphics card. That might enable you to use the GPU acceleration in Lightroom. It will speed up many tasks in Develop but not all especially on high resolution displays. If you can't get it to work even with only the discrete card enabled, you should see if you need driver updates for your card.

                I found the driver update for Nvidia on their website and I can use the GPU acceleration now with 960M ... but it's not exactly the smoothest still and the brush tool still lags about 1 sec. Also, I checked my CPU usage and it peaks at 100% sometimes a lot of the times when using Lightroom actively, is that normal?

                If I don't use any GPU acceleration it's even slower...

                 

                I don't understand why it's so slow, is it simply because the 4k display takes up too much power?

                 

                This is my system info if that helps

                  That's unfortunately pretty normal. It takes a lot of horsepower to render images at the resolution you are working at and this is not a very high powered gpu. If you run at 1/2 resolution you'll see it being much faster as it only needs to calculate 1/4 of the data. This sort of raw processing of high megapixel cameras and on high res displays is at the edge of what you can do.
