guys, i’m having a whale of a time getting acceleration with texture fetches in my vertex shaders
to be clear, it works, but it’s not accelerated.
tried these formats:
using texture2DLod(s, xy, 0.0) for sampling.
it seem some folks have had success with fiddling with the texture format, but try as i might i can’t get it to budge.
the opengl vertex texturing demo from nvidia works nicely, but uses nv_vertex_program3.
3dlabs validate says all is ok. infologs are clean. no opengl errors either
p.s. it strikes me as incredibly freaky to need a 3rd party tool to tell me what my own compiler should
geforce 6800 gs
forceware 82.12 and 83.90 (beta, no official drivers exist for this board, yet)
glsl 1.10 via cg 1.3 compiler
windows xp sp2
