Question

Extremely Slow lightroom import/use performance

Hello All,

I have been using Lightroom for several years now and I have never had a problem with its performance aside from a few little quirks.

Whenever I have used Lightroom, it is always a case where I have a high end PC. I have built all my PC's and have never used one (for personal use) that comes fully built from a factory.

This being said, the GPU's in the computers I have used have always aided Lightroom in its operations. I have never had had to disable the GPU acceleration in the preferences.

This time, it is a bit different. I recently built a brand-new computer utilizing AMD's new Threadripper 2950X along with an AMD Vega 64 GPU. Whenever I tried importing, in this case it was 835 24mpx photos, Lightroom would begin the importing process but it would take an abysmally long time, and during this import it took 6 hours!!! That is ridiculous. I restarted my computer (several times) checked my hardware, software, antivirus, firewall, malware....you name it, I checked it. I also did research on this forum but to no avail...there was no fix. I upped the cache size to 20GB, that didn't help either. Like I said, I have NEVER had this problem before. Lightroom would always import at a reasonable speed. Lightroom is fully up to date. Drivers up to date, OS up to date. No viruses or malware.

In one of my last troubleshooting instances, I decided to turn off GPU acceleration and Lightroom magically decided to work the way it was meant to work. After 3 days of trouble shooting, the simple answer was to uncheck a box in the preferences.

Anyone else having this type of issue, but was able to fix it another way?

I am not sure as to why Lightroom is not communicating with the GPU correctly, or if it is a hardware snag on my end, maybe a software issue??? I don't know, it works as it should now.

TL;DR - If you are experiencing horrible import performance, disable GPU acceleration in the preferences.

MY Computer specifications:

  1. Processor: AMD Threadripper 2950X
  2. Motherboard: ASUS ROG Zenith Extreme
  3. Ram: G.SKILL TridentZ RGB 64gb
  4. Graphics card: Saphire Nitro+ Radeon Rx VEGA 64 GPU - 8GB HMB2
  5. NVMe Storage: (2) Samsung 970 PRO M.2 512gb - (1) Samsung 960 PRO M.2 512gb
  6. SSD Storage: (2) Samsung 850 PRO 512gb - (1) Samsung 860 EVO 2TB - (1) Samsung 840 EVO 512gb
  7. Operating System: Windows 10 PRO 64bit

    Also

    1. On what hard drive is your catalog located

    2. How much unused space exists on that drive.

    3. On what hard drive is your Camera RAW CACHE located

    4. How much unused space exists on that drive (not as important as 2)

    1. On what hard drive is your catalog located

         C:\ Drive. M.2 Samsung Evo 970

    2. How much unused space exists on that drive.

         100GB

    3. On what hard drive is your Camera RAW CACHE located

         Same drive.

    consider moving both the catalog and the CAMERA RAW CACHE to another drive other than the C drive. In other words, not on the OS drive.

    make sure that you have at least 25% hard drive free space available on whatever drive you place the catalog in.

    yes, fastest drive is best, but perhaps not C. Avoid competing with OS operations in read/write from/to drive when possible.

    also better to relocate camera RAW CACHE elsewhere than C.

    Perhaps a corrupted or out-of-date GPU driver?

    I have the exact same problem. Running i9 9900k + Vega 64 GPU. A shame it doesn't run like it should. My Macbook Pro from 2014 runs faster than my brand new build.

    Using the brush tool, toggling red overlay, zooming in and out, just general workflow in the UI. Exporting is fine. Compared to my 2014 Macbook Pro this is running much slower.
