LabWindows/CVI Timer Functions Run Improperly on AMD Athlon 64 X2 Systems

[CB4]

"My timer functions run improperly on PCs with AMD-Athlon 64 X2 Processors, but seem to work on other systems. Why am I seeing this behavior?"

I am wondering if later versions of CVI will have a fix for this problem rather than constantly updating the boot.ini file in the host computer.  I noticed LabView does not have this problem.

Can someone tell me if National Instruments plans to fix this in CVI, and what version of CVI will have this fix?

QueryPerformanceCounter on AMD Athlon64 X2 processor is known to have problems.  If NI used QueryPerformanceCounter to implement the timer functions then this could be the problem.  It's more of a Windows problem than an NI problem.
