The rotation isn't smooth like it is in the 32 bit version.
I think the difference isn't 32bit vs 64bit, but rather the version of QT that the respective builds use.
The 32bit build uses QT4 and the 64bit uses QT5.
On the 64bit version you can try to navigate to the bin directory and find the file openglsw.dll and rename it to opengl.dll, then restart FreeCAD. See if the problem goes away.
