FYI I recently was testing the theoretical limit on a card and went down the path of: `glxspheres -p 1000000` "no difference" `glxspheres -p 10000000` "hmmm, not breaking a sweat" `glxspheres -p 1000000000` "wow" Then I took a trace and found out that the number of actual ROPs was no different between 10 million and 1 billion. gluSphere() apparently hits a limit on how much geometry it produces and won't go higher (increasing window size didn't do anything; I didn't read the GLU source). Bottom line: `glxspheres -p 3500000` (which equates to a little over 14 millon ROPs per frame) is the highest load the stock glxspheres/libGLU will produce. -Nathan -- Nathan Kidd OpenText Connectivity Solutions nk...@opentext.com Software Developer http://connectivity.opentext.com +1 905-762-6001 ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
