Hi. 
Sometimes even with just one prop iCLone suddenly becomes very sluggish. It happens often when I have "Reflection" checked in the Materials tab, then if I uncheck it, everything goes back to normal. Other times, with only a few props, it becomes sluggish.  In Task Manager CPU is barely breaking a sweat, RAM is at 37%, in iClone GPU is at 1.4 / 8 Gigs (Nvidia GTX 1070). Everything becomes sluggish: moving or rotating props, browsing the menus, etc.
Any ideas?
Thanks
