OK, maybe that has to do with my big catalog file that has taken LR4 of LR3, I thought. So acquired catalog in LR cleared 4 (LR3 runs parallel with its own catalog on), created a new catalog and read a list with 2,500 images. Unfortunately, that did not bring any performance improvement.
At the computer, it may actually not be, eventually LR 3.6 runs fast enough, but for completeness:
Intel quad-core CPU, 8GB of DDR3 Ram, 128GB SSD, very fast 1TB HD, Nvidia GTX 570 and Windows 7 64bit. Are processed so that only 12 MPix-RAWs a Nikon D300s.
Now I'm sitting there, a high-performance LR 3.6 and a non-use of these underground performance LR 4. Since I am convinced of the new development tools in LR 4 and also the integrated geo-tagging module (also very slow) would like to take, now remains only to hope that Adobe quickly released a high-performance version 4.1.
A word to the packaging:
Adobe has always appeared in the past so a little creative when it comes to packaging, but with LR 4 you have the bird shot: The DVD is in a paper bag, this in a small box (13x13), this then in a bigger carton ( ca. A5), and then in turn inserted in the printed packaging with a folding flap.
Oh, except for the DVD contains only air in this onion packaging. At a Quick Start flyer or even a printed manual Adobe has (probably for environmental reasons) waived again, the more surprised one of these unnecessary packaging delusion.
