LR CC is Slow

[marcelk10526647]

Good Morning. I have a Macbook Pro Retina, i7, 16GB RAM, 1.5GB video card and even then the Lightroom CC is slow. I was using the LR5 previously, and it worked very well. As I bought a CANON 5D mark4 I had to upgrade. Does anyone know how I can solve this problem? Maybe some LR setup? Thank you

Exactly what tasks in Lightroom are slow? Please be very specific.

[marcelk10526647]

It gets slow in develop mode. It takes about 2 to 3 seconds to load each photo, slow when using zoom, crop and when I use the X and U keys to filter photos.

What is the exact make and model of the video card?

What is the exact model number of the i7 processor?

What is the size in pixels (do not tell me inches) of the monitor?

What happens if you change the setting on using the Graphics Acceleration? Go to Preferences->Performance Tab->"Use Graphics Processor"?

Try turning it off.

It seems to me that you have changed cameras to one that takes a relatively large RAW images (30 Megapixels), after using one that presumably took smaller RAW images, and now suddenly your Lightroom is slow. The culprit is the new larger size of the images. In addition, it seems to me that you have a relatively underpowered computer (although you haven't really provided the exact make and model of your CPU), and more processing power (faster CPU) would certainly be helpful with 30 MP images. Also, you have a relatively underpowered graphics card that (as far as I can tell) is not supported for graphics acceleration in Lightroom.
