The new gDEBugger V4.2 adds full support for Frame Buffer Objects (FBOs). It enables developers to view allocated FBOs and Renderbuffer objects, FBOs attachment points (depth, color and stencil) and Renderbuffers data as an image and raw data. This version adds full support for OpenGL context sharing. Shared objects are now displayed in each and every render context that shares them. In addition, NVIDIA GLExpert driver (v2.0) was integrated into this version. gDEBugger, an OpenGL and OpenGL ES debugger and profiler, traces application activity on top of the OpenGL API, lets programmers see what is happening within the graphic system implementation to find bugs and optimize OpenGL application performance. gDEBugger runs on Windows and Linux operating systems.
