I notice that there is a new message line, "Extra SSE boost OK.", added.
You must have downloaded the new 3.25 client. From stanford's site here's the blurb:
F@H Beta Change log wrote:
- If -forceasm is used, then on every execution of the core until the
client is restarted, SSE optimizations will be used if possible (if
the chip is an AMD chip, then be default, without the flag, it would
not be chosen over 3DNow). Prior to this client, this effect would have
held true only for the first work unit run after starting the client.
Shouldn't make of a change for most people, but won't slow you down any either.
