I'm still dealing with unresponsive sliders and slow application of adjustments with LR4.1 has anyone had any luck correcting issues? I know some were never effected and some issues were corrected with the 4.1 release but I wondering if any of you who had issues after 4.1 have gained any ground.
After upgrading to 4.1 my issues have all been corrected as far as I can tell. The speed has been much improved, in fact I am thinking it might even be a little fast then 3.6... Sorry to here you are still have issues as I know first hand how frustrating that can be. Have you tried rebuilding all your previews from scratch? That has helped some people in terms of speed.
I think LR 4.1 is clearly faster than version 4.0.
A small cosmetic bug in the Library module is not yet fixed, though: when moving the mouse from the image area to the panel of keywords on the right (e.g., to set check marks to the names of persons found in the current picture), the cursor changes to left-right resizing arrow in between the panels but does not always change back to the pointer arrow on the keyword panel side. Of course, the mouse still keeps working.
I have completely rebuilt the catalog with no luck. I'm hoping we'll see a fix soon. the results for this program are excellent but the performance lag is something I can only tolerate for short periods of time
you did not tell what kind of computer you're using (Windows or Mac), how old it is, how many cores the CPU has or how much RAM you have.
One place to check is the Camera Raw Cache Settings in the File Handling tab of the Preferences dialog. I belive the default is 1 GB. I learned from an Adobe web site recommending setting this to 10 GB or more.
Another tip might be to render proper size preview when importing images. Then the change between normal and 1:1 view does not take so long.
Certainly it helps to have more cores or CPUs and RAM. Having a fast hard disk helps, too, but I don't think many of us would be willing to buy a whole new computer just to do some post-processing.
I have a 4-core AMD CPU (four year old machine), 6 GB of RAM, a quite ordinary hard drive and relatively modest graphics adapter. I can see that all the cores are in full use when Lightroom renders images. I also have a 24 inch monitor and usually run Lightroom at maximum size. That means that the image shows a lot of pixels. I don't know how much this affects the performance. I also don't know if Lightroom is capable of using NVidia GPU to perform computations; probably not.
admittedly my machine is not ideal for this work but LR3.6 was MUCH faster. I'm running a dual core 32 bit windows machine with 4Gb ram. I have my Camera Raw Cache set to 40Gb. I do render to full size on import. I am in need of a hardware upgrade but its just not in the cards right now. I just hope a workable fix will allow me to run 4.1 on this machine.
Update : Im a little embarrassed that i disnt think to check for this issue in the very begging but now that I have I thought I would remind others here. It seems a great deal of the issues I've been having were caused by older video drivers. Once updated things are much better.
