Text Geometry Node not working on buffered nodes

hi there, I am working with the Text geometry Node (dx11), everything is fine if is connected to a goureaud directiona or a cosntant node , etc , but when i connect to the gouread buffered, nothing happens, it doesn show anything, i tried to use the ex9 tex geom with a mesh join with a dx11 mesh and, is the same i can’t see anything. Any Idea why is this happening? some help.
The thing is i need to put the countries names of a databases, on the vertex positions, of a geom, so to process 145000 (3d positions) on cpu reduce my FPS, so i need the buffered power.

thanks a lot.
