Lightroom sluggishness with Nvidia drivers

SNAG · 25th May 2008

Hi all,

Thought I might want to post this for future reference:

I was previously using a ATI X1600 card on LR 1.41, and everything worked beautifully.

I upgraded my card to a Nvidia 9600GT yesterday, (running Forceware 175.16) and realised that LR was running sluggishly with loading and refreshing images. As I did not install nView, that wasn't the case (some documentation online linked the sluggishness to nView s/w).

However, I realised that there was a setting that caused the issue (might need to show advanced settings):

3D Settings > Manage 3D Settings > Global Settings > Multi-display/mixed GPU Acceleration

By default it should be multiple display performance mode. Change this to a single display performance mode (I only have 1 screen anyway).

This worked for me beautifully.

if i am not wrong, lightroom is more RAM-intensive, and does not rely so much on the GPU (graphics processor) unlike something like aperture. could be a RAM issue, i think.
