I'd like to report that the 32-bit version of the normal gesture viewer "gesture_viewer.exe" is extremely slow, something like 1 fps or 0.5 fps. I'm using Windows 7 64-bit.
The other versions are working. Here is a report of what different exe files are doing:
win32\gesture_viewer.exe - ~ 0.5 - 1 fps performance. I mean 1-2 second per image.
win32\gesture_viewer_simple.exe - full speed, ok
x64\gesture_viewer.exe - full speed, ok
x64\gesture_viewer_simple.exe - full speed, ok
