I too upgraded from 5.3.5 to 6 (trial version) on a system running Windows 7 with 2GB memory and a 2.4ghz Core 2 Duo. DxO6 does seem much faster, but crashes after 25-35 images. Has anyone else had this problem on a 2gb machine?
DxO support suggested getting more RAM (I'm working on it.) They also suggested a long and complex procedure for collecting debug information. I will try that if the extra RAM doesn't help.
Edited by OP:
After adding 2gb to my Win/7 machine and doing other trickery with memory management, I was able to run 111 pictures through DxO6 without difficulty.
DxO6 seems to be faster than versions 5.xx, perhaps about 30%.
The trickery involved how Windows 7 uses the extra memory. After installing the RAM, my system showed only 2495mb memory, not 4096 (4gb). And DxO6 would run only about 90 images before crashing. After some Googling, I found that Windows XP, Vista, and 7 use memory above 2GB as resources for the operating system, leaving only part of the extra memory for applications such as DxO.
But when I turned on "Memory Mapping", the available memory dropped to 2gb, but DxO ran better, without crashing (111 images.) To turn memory mapping on, it is necessary to enter the computer BIOS, usually by pressing DEL while the computer is starting.
I don't fully understand the technical details, but interested users can Google "Windows 7 Usable Memory".
