Re: [osg-users] FBO and WGL_ARB_render_texture
Hi, It is possible that I solved the problem. In fact, my card GeForce FX 5700VE was declared AGP in the bios. By changing AGP to PCI OSG all is correct. Games and programs that were not working, working now and I have no problem. Thank you!

Re: [osg-users] FBO and WGL_ARB_render_texture
hi Robert, I get the same version string: OpenGL version string: 2.1.2 NVIDIA 177.82 Yet I most probably have a less recent Graphics Card than you : I have a NVidia Quadro FX 550 Do you think this is the reason? Why doesn't it occur every time?

I'm not familiar with the FX 550 so can't comment on it's capabilities. Have a look through what glxinfo reports. Why doesn't it occur every time? I can't answer this.

Hi Loic, I've just done a testing of using --hdr in osgprerender (--fbo is the default where supported) and it works fine. I'm using Kubuntu 8.10 + Geforce 8800GTS. glxinfo outputs lots of stuff including the version info: OpenGL version string: 2.1.2 NVIDIA 177.82 Check which version you are using, as it does sounds like you are encountering a bug.
