You don't say what drivers you tried. If you downloaded from nvidia.com they probably won't work, because FBO is supported only by beta drivers. I downloaded the latest 76.45 from www.guru3d.com and it works.

*decodes the AP's post*
its a better and true render-to-texture system, where the data ends up in the texture. With a pbuffer the data stays with the pbuffer and is just aliased by a texture ID, also using a pbuffer requires 2 context switches (to and from) where as FBO requires none.

I have 76.91 and it works fine (not from guru3d tho)

What actually happends for you? does it not appear in the extension string? do the entry points screw up? do you simply have an old version of glext.h which is hasnt got FBO in it yet? tell us.

Read the section on FBOs here. You may find it useful.

I checked it with sisoft sandra (he pulls out gl string).
And try to run FBO example from nvidia.
And all I get is "Unable to load the following extension(s): GL_EXT_framebuffer_object"

I was on the discussion on opengl.org forum few days ago.
Try all the things. But without success.
May be, I just wait for non-beta drivers ;-)

Have you tried a driver cleaner before installing a 75 series? YOu may have an old dll in the path.
