Hi Alexy,
I used the highest settings for Dense Point Cloud Generation. My computer specifications are:
Intel Core i7-2600K @3.40 GHz, 3801 Mhz, 4 Cores, 8 Logical Processors
RAM: 24GB
64 bit, Windows 10
One GPU: NVidia GeForce GTX 560 Ti
As you can see from the Task Manager screen shots the CPU useage is in the 3-5% range while the memory useage has been consistently up in the 97% range.
Also, the program is still running this morning which is good, although the time left has increased to 49 hours.
Thank you very much for your help, Alexy!
