Poor LR-performance

[TomasHermansson]

LR-friends.

My LR is getting slower and slower over time. To overcome this I decided to spend some money on my hardware...  but still slow...why?

I upgraded the graphics card to a GeForce GTX 1050 Ti / PCIe - no significant improvement

Then I decided to change motherboard (Asus H270-PRO), processor (Intel i7-7700 4.2 GHz) and memory (64GB DDR4 2400MHz) ... I kept my SSD and Windows 10-installation - but still no boost of performance.

For example;

When I open/change image the right tools panel is redrawn, I am able to see the tiles drawn.

When I am using filters for adjustments with my Wacom (or mouse) I can draw and when I am done the effect of the filter is shown... I have to wait to see what effect the adjustment had to my image... when I have lots of adjustments this is really annoying, draw - wait - draw - wait... ops, undo and redraw - wait...

What’s wrong? I believe I have Close to the fastest h/w currently available... the CPU utilization isn’t high while working within LR... why?

I am eager to get this resolved... should I do a Clean install of my computer?

If you are doing a lot of brushing and/or spot healing, this is a known issue in Lightroom. In my opinion, you have reached a limitation of the non-destructive editing paradigm in Lightroom, and also a limitation of your hardware to do the calculations in "real time".

Some things you can try:

1. Turn the GPU acceleration off (brushing and spot healing actually get slower with the GPU acceleration on)
2. In Lightroom, do the brushing/spot healing as the next to last editing step, and the last editing step would be to turn on the lens corrections and transformations
3. Do the brushing/spot healing in Photoshop Elements or Photoshop
4. Normally I say get a faster CPU, but it seems like you have a very fast CPU (for anyone else reading along, increasing CPU speed will improve this problem, but I can't say if it will improve enough to make the problem go away)

Thanks for your answer!

1) I tested to disable the GPU... when I adjust the Tone Curve with or without the GPU... its sooo slow... no big difference
2) ok, I usually do the brushing as the last step... 3) Photoshop might be an alternative but I would slow down my image processing... I usually have 100+ images each time...

4) yep, I Think I got Close to the fastest CPU on the market right now...

But the point was to test the brushing/spot healing, not the Tone Curve, with the GPU off.
