Nvidia drivers 1.0-5328 Problems with ARBvp1.0

Hi there.

I’m not sure if this is a Linux specific problem, but since I only have the possibility to try it on Linux I’m posting it here.

I have an ARBvp1.0 and get an error on the following line
DP3C R2.w, R0, R1;

R0,R1,R2 are all used as temporary registers.

Well the program ran fine with the driver 1.0-4496, but after installing the new driver, I get the aforementioned error.

Can someone tell me if something changed in the ARB vertex programs concerning command syntax or if this might be a driver bug.

Thanks in advance


Looking at the ARB_vertex_program spec, it doesn’t look like DP3C is a valid instruction.

Thank you very much. I never would have found this on my own.

Your absolutely right. DP3C is only valid if you’re using NV vertex program2.
