GLExpert: What is it?Helps eliminate performance issues on the CPUOpenGL portion of the Instrumented DriverOutput information to console/stdout or debuggerDifferent groups and levels of information detailControlled using tab in NVDevCPLWhat it can do (today)GL Errors: print when they are raisedSoftware Fallbacks: indicate when the driver is in fall backGPU Programs: errors during compile or linkVBOs: show where they reside, mapping detailsFBOs: print reasons a configuration is unsupportedFeature list to grow with future driversCopyright © <strong>NVIDIA</strong> Corporation 2004
