to have a procedural skydome texture above my head, i use perlin noise and glTexSubImage2D() function.
when i update the whole texture, everything works good, but is a bit slow.
to make it faster, i use the texture as a wrappable buffer, and i update only a single line of the texture while i modify the texture matrix accordingly to make the texture scroll.
well, if i use the generic MS implementation, it works.
if i use the nvidia ICD driver (tested on a tnt and nv10) it don’t work: it seems to don’t accept lines != 0 into the offset param.
have i found another nvidia ICD bug?
what are your experiences?
