After executing such sequence:
the value of the program.env is equal to (0,0,0,0). Is it a driver bug or a correct behavior?
Hardware: GeForceFX 5200

You don’t need to bind before making that call and I don’t think you need to have FP enabled.
How do you know it’s all zeroes?
I modulate with program.env in FP and it looks like it’s black, not white.
I also experienced this, for local constants, It worked in cases when i didnt change the program ( kept the one all the time) but when i changed to another and back again the parameter wasn’t updated ( bump specular), i moved the constant into the program itself and that worked… I dont own a FX card so i couldnt test it anymore, but it felt like a driverbug. ( same program worked on an ATI card, but since that is what i develop on its not that strange )
Really, It works only when I don’t switch to another program. Looks like we share the same problem.
Damn, is there any bug-free driver?
My program doesn’t work on ATI due to their render-texture bug, which is not being fixed for three or four months despite the fact that I sent a bugreport to them
