How to use GpuPerfStudio 3 to get gpu info from Chrome running a WebGL application ?

The server process sends messages to the client but the client application selection dialog stays empty.

Chrome consists of multiple processes may be that is the issue.

There is a commandline option --single-process but that does not work anymore (chrome does not start), will file a bug for that.

Any other ideas ?

This is with Chrome  37.0.2062.124 m (64-bit)  and PerfStudio 3, version 3.0.64.0 on Windows 7 64 bit

Re: How to use GpuPerfStudio 3 to get gpu info from Chrome running a WebGL application ?

Hi,

It all depends on how Chrome implements its double buffering in WebGL. The PerfStudio OpenGL server intercepts the wglSwapBuffers (or glXSwapBuffers on Linux) and this is where it does its housekeeping. If an application doesn't use *SwapBuffers, then the server can't get into the application, which is why the application selection dialog is empty.

Thanks,

Tony.

Thanks for the info.

--no-sandbox on the command line does the trick.
