Radeon Shaders Broken.

I did a few more tests... It appears libGLEW v1.5.2 does not properly detect, and that is what causes the framebuffer object to not work

Phew, glad that finally got sorted out.

vdrift: include/cartelemetry.h:63: void CARTELEMETRY::Update(double): Assertion `file' failed.

I think this is happening because it's trying to write telemetry to a file in whatever folder you're launching the executable from. It shouldn't be doing that (we should write any telemetry to the ~/.vdrift folder, and probably only with a command-line switch to enable telemetry). In the mean time you should be able to get this to work by running the executable from a folder where you have write permissions like /tmp or ~.
