Who does not want to ruin his performance on the computer currently does not upgrade.

I have current and good hardware, all software products are purchased with a license, I never had problems with the processing of my pictures not with Lightroom to 3.6 even with RAW converters or Adobe Elements 9 and 10 and various expensive filters of NIK and Alien Skin. My hard disk is cleaned and serviced properly by me.

Now I have installed Lightroom 4 and since then the performance is there. Countless crashes, the Catalog Access and thumbnail takes much longer to be able to long for it somehow bearable accept yet. Moment during the initial measurement of the newly stored in the catalog 300 photos I took several hours. Again and again "no feedback" and crash the system, no leaves in different windows possible. Commands are accepted very delayed or you have to repeatedly click on it. The cursor no longer flows through the screen, the pointer moves delayed and intermittently only. Until an image displayed vollstänig will pass more than 10 seconds, as are individual processing steps with a time delay to see. The processor runs continuously on high speed.

After several possible error analysis I've decided the software again to remove it. 70 Euro for the chimney. In future I will buy no more products from Adobe, as I prefer to wait half a year to the problems - if any - are resolved.

Those who do not necessarily need to wait should.
