OpenGL Headline News
gDEBugger, an OpenGL 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 application performance. The new V2.3 introduces a Calls Statistics view that allows viewing the number of times each OpenGL function call was executed in the previous frame and it’s percentage from the total functions execution count. This helps you to locate (and then remove) redundant OpenGL function calls, state changes, etc.
This version also adds support for GL_ARB_texture_rectangle and GL_NV_texture_rectangle.
