From the following post in Hardware
The effect of SSE2 in P4s

To disable SSE2, I put "CpuSupportsSSE2=0" in local.ini.
CpuSupportsSSE2=1 in local.ini should enable it.

Prime95 may use SSE2 depending on the CPU features only
( if it detects the features at runtime,
if not (just info in a table) then either
the CpuSupportsSSE2=1 or the type 12 for P4 is needed )

What really determines what hardware features are used/code path run ?

Is it runtime detection of CPU features ?
Is it settings in local.ini ?
Is it some combination with overides ?
