Graphic Remedy has released a new version of gDEBugger that allows you to pinpoint the exact location of application performance bottlenecks in the graphic pipeline. gDEBugger, an OpenGL API debugger, traces application activity on top of the OpenGL API letting programmers see what is happening within the graphic system implementation.
Version 1.3 includes a set of commands enabling you to turn off the graphic pipeline stages one after the other. For example, you can turn off stages such as: Eliminate all OpenGL Draw Commands, Force Single Pixel View Port and Force 2x2 Stub Textures. By following application performance using the heads-on FPS display when turning off individual stages, you can determine the exact location of a bottleneck.
