Profile OpenGL / GLSL with NSight?

Development Tools Nsight Systems Nsight Eclipse Edition
#1

Is it possible to profile OpenGL with NSight? All I get from it and nvprof is:

======== Warning: No CUDA application was profiled, exiting

Thanks

#2

Nsight Eclipse Edition does not support OpenGL profiling.

#3

Hm, that’s a shame. Any recommendations? Preferably FOSS or at least gratis? :)

Thanks
