I didn't try the suggested approach in the answer yet, but<br />
it makes sense and looks like it will probably work well.<br />

Is there a quick check you can do to find out if the RDTSC (time stamp)<br />
instruction<br />
is supported on the particular CPU that you're running on?<br />
<br />
I know you can back this out by doing a bunch of tests to see what brand<br />
and model<br />
CPU you have, and then figuring out from that info if the RDTSC<br />
instruction is supported,<br />
but I'm hoping to have a simpler runtime check that doesn't require us<br />
to keep track<br />
of every CPU brand and model.<br />
<br />
Currently if you execute the RDTSC on cpu's that don't support it, Win95<br />
pops up a<br />
box about an illegal instruction. Is there some way you can attempt to<br />
execute the<br />
RDTSC and then catch the fact that its not supported before Win95 gets<br />
upset<br />
about it? If so, will this work on NT also?<br />
<br />
Thanks for any help you can give me-<br />

Checking for RDTSC support

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.
