Anyone else tried using interleaved array format GL_T2F_N3F_V3F (and as it seems to me all the other “V3F” formats) on a Rage Pro card?
I tried this with various versions of the ICD drivers, but with every there is a very noticeable that can be observed, namely that the polygons that do not lie completely within the viewing frustum are not clipped as they are supposed to, but they dissapear as a whole. Even more worse it is in combination with the GL_EXT_compiled_vertex_array extension.
When using other formats (to my experience the “V4F” formats), everything works just fine, but well the performance is not that high as with the V3F formats.
Anyone sharing similar observings?
