GPU acceleration uses >90% of graphic card memory - normal?

Hi everyone!

by activating the full GPU acceleration in the LR settings I find the following effect:

 

LR uses a lot of graphic memory. After working on 2 or 3 raws, 90% of the memory is used by LR.
The system runs stable but I´m afraid this will affect other GPU-accelerated applications, e.g. PS, wich I uses parallel to LR for the fine-tuning of my pictures.

Using the GPU only for the display output needs only 25% of the graphics memory.
I used the search but could not find any topics with this issue. 

 

So I would be thankful if anyone can tell me if this is a normal behavior wich would not affect any other applications of if this is a bug. Are there any solutions?

 

Here are some system-informations:

Windows 10 (Ver. 1903)

LR 9.1

32GB RAM

CPU: AMD Ryzen 5 2600

GPU: Nvidia Geforce GTX 1050 TI

GPU-RAM: 4GB 

GPU-Driver: 441.66  - Studio, 10bit support activated

Have you tried updating the graphics driver from the Nvidia website? When installing new drivers make sure to select 'Custom' and check only ‘Graphics Driver,’ ‘Nvidia WMI,’ and 'Clean Install' boxes.

This excessive VRAM usage has come up a number of times recently. Several posters have had Lightroom go straight to 90% or so upon launch.

 

When I checked my own Quadro P2000 it did not happen. Lightroom took about 0.8 GB out of 5 total, and stayed there throughout. It was not possible to get VRAM usage to increase significantly beyond that, except in brief transients.

 

So the evidence so far clearly points to a driver bug. For a while I've been convinced that Quadro drivers are less prone to bugs than the GeForce drivers, and this seems to confirm it.

I have noticed the same results, but have also experienced a recent symptom. When I am using LR and editing images in PS, PS will either lag or freeze and won't resume until I either wait, or toggle to another program and back. I have only recently experienced this and I have been doing the same processes for years, and almost 2 years on this machine. If I quit LR and open the same image in PS, the lags and freezes go away.

 

Windows 10

Latest version of LR and PS

32GB RAM

Nvidia Geforce 1070, 8GB GRAM

    Thanks, that did the trick! I assumed that when I asked Windows to check for an updated driver that it would be correct when it said that it had the current driver...my bad!

    I'm seeing the same GPU memory usage with a similar spec'd system with no impact to LR or PS performance. I suggest try editing in both LR and PS and see if you have a performance slow down. Lacking that I wouldn't worry about it.
