Nsight 4 rc1, Opengl APP trace broken

Worked with Nsight 3.2 version quite for a while, doing Trace Application with System, Tools Extensions and OpenGL trace settings. Everything was fine, cpu and gpu frame captured succcessfully, and timeline awas available.

When tried tracing my app with Nsight 4 RC1 after stopping capturing NSight says “there are N CPU frames and 0 GPU” frames. And there are always zero GPU frames, so timeline is left unavailable.
Any clues what i`m doing wrong?

Thanks for attention.

Hi msomeone,

Are you using recommended driver 334.89? And what your GPU is? If you don’t mind, could you provide us your application? If it’s too large to attach, ping me and I will give you an FTP link. Thanks.
