-Admin rights: yes. I take it that by this you mean the service(s) on controller and/or generators for Loadrunner having admin rights: that's a yes. If you mean otherwise, please let me know.
-CPU consumption above 80% for entirety of the test, with few exceptions: usually at full 100% CPU.
-No mismatch in LR version patches; everything at LR 11.52: controller & generators. As far as I know, Windows 2008 has same patches on all servers; same for .NET. Are you indicating that Windows and/or .NET patch discrepancies would cause this high CPU usages on generators? (I assume it would be discrepancy between controller <--> generator windows patches)
Unfortunately, we have "official" support for HP Loadrunner through SAP: it's how the contract is written. I'd hoped someone else had seen this same situation, knew an easy fix, or something to try to alleviate the situation.
