Gérald/Dan :

Just wanted to report that my nVidia GeForce GTX 650 (2048MB RAM) is working fine with ver2 demo so far with static drape testing. Still need to test animated drapes, but it looks like minimum requirements can be below the recommended 700 series.

Also, just an FYI - you have two script folders for install - 'ver2 demo' and 'ver2.x' -- The DSE scripts in the demo folder (which I believed should be installed) do not work - just unspecified 'failed to start' error, look in Log File, which just states script 'failed to start'.

The scripts in the 'ver2.x' work, but this might be confusing to newcomers wishing to try the demo -- As I am not a newbie at this, I knew the avenues to pursue to get a working version (first used the beta DSA scripts), but I would not have installed the 'ver2.x' folder where I believed this would be for when I purchased the upgrade -- Using the demo, I only would install the demo folder...
