I've downlosded Lightroom 4.1 RC2 but deveop module is still painfully slow anyone know how the problem is is solved or when a solution is likely going to be available. This is seriously affecting my business now.
The engineering team are aware of some remaining performance issues and are working to addrress them. As users we have no indication of when the fix might be forthcoming. In the meantime, it might be helpful if you provided details on hardware, OS, and specific issues you're having.
Note that painfully slow tells engineering very little about where and what to look at.
Ian my system is an Intel core i7 920 @ 2.67 GHz, 12.0GB RAM, ATI Radeon HD 4800 Series. In develope mode the slideres are not smooth. Doing anything at 100% takes ages to show adjustments, trying to navigate around a 100% image takes between 5-10 seconds to load, everytime I try to scroll around the image. When sharpening, holding down ALT key to see changes takes 3-4 second to show the B&W adjustment screens. The worst is when using the selection brush, I have to wait several seconds to see any adjustments so when you move the sliders nothing happens for several seconds making it very difficult if not impossible to use the sliders I have to make changes in 1 step intervals and wait several seconds for the change before I can make the next one. While all this is going on the screen also blacks out.
Hopefully that makes my frustration a bit clearer. I understand this software is very complex I just feel that with so many poeple having serious issues with it. Adobe released it to early, being such a reputable company I assumed it would be safe to buy this software.
My system is a Intel Core2Quad, 4 GB Ram and Windows 7 32bit - I am aware this is not a great constellation but LR 3.6 worked fine so far. As others mentioned LR 4 RC2 is still "painfully slow" and I really think of downgrading to LR 3.6 again. Develop module is really slow - I don't want to be more specific because I am sure you know what I'm talking about. It is almost unusable and a poor "user experience"!
