GL3 Shader Error (could not load gl3 shader)

GL3 Shader Error (could not load gl3 shader)
Hi everyone!

i get an GL3 Shader Error (see log below) when i start vdrift, so it switches to GL2 for rendering. Is there a way to fix this, so i can use GL3 instead of GL2?
Another problem is that vdrift uses the CPU instead of GPU to render the scene, although it recognises my graphics card.

i have a nvidia quadro 2000 and using driver version 297.03. Vdrift (development version) is running on a windows 7 x64 operating system.


Here's the log:

Here's the profiling, where you can see that the rendering is done on the cpu:
