adapted SHOW_ALL_LIMIT value for VR purposes (best fps performance most important)
ﾒﾍﾀﾒﾍ

In fact the lower the value, the faster such a directory will load.
However, scrolling fps performance will be very bad (due to live
drawing). So, for VR purposes it's better to draw every single file at
once - better fps performance. 10000 files limit seems to be "optimal"
