View Full Version : Vertex Program on Geforce2

03-13-2001, 01:01 AM
Hi, I am trying to use Vertex Programs on nVidia's GeForce2, but every time I use glEnable( GL_VERTEX_PROGRAM_NV) I get and Access Violation error on NVOPENGL.DLL.
I am currently using Creative GeForce2 GTS, with Detonator 10.80 drivers for Win95 in Visual C++ 5.0. Has anyone ever encountered this before? Any advice would be greatly appreciated!

Sorry I can't give you any suggestions but
I am successfuly using nv_vertex_program with 10.40 win2k drivers on my GF2MX.
I havn't encountered any problems with my code or with demos from nvidia sdk.

it crashes often, yes.. for example when the program itselfs ( the vp ) is wrong written or you forgot something in etc.. it could be that it crashes when you enable and then render something without setting a standartprogram.. no one knows.. they arent official yet http://www.opengl.org/discussion_boards/ubb/smile.gif

perhaps try 1050 or like the other one 1040..

You may try to enable the NV20Emulate option (in registry).
You can use geforcetweak to do that.

Oh, I found out what's the problem. Apparently there are mistakes in my vertex program, but once corrected, the NV_vertex_program extension works fine.
Thanks everyone!

Nvidia as a debugger for shaders. It really helps!
