rottweiler said:I guess it's like Hito said, if there was an error shutting down the core previously it turns SSE boost off.
Looking at the logs I see this is what matters:

The second one is the same thing Hito posted, I'm just showing the difference for anyone else who might have had this problem.Code:[11:36:19] Preparing to commence simulation [11:36:19] - Looking at optimizations...

If it sees there was an error the last time it ran, it uses standard loops, which I guess turns off SSE boost.
So -forceasm doesn't actually force it to use SSE, only if there wasn't an error previously.
At least now I know, "And knowing is half the battle."![]()
Actually, that is exactly what -forceasm is for. If you are running the clients as a service, you will need to edit the registry and change the registry entry for them to use the -forceasm switch. I had an occasional problem because of this before I added the -forceasm switch to the registry entry.
