I have a desktop dislay which has shown CPU usage at 99% since 1st beta ..... Task maanger process tab howver usually has me about or jjust under 50% on my lappie Core Duo (XP). Have to look at the Win 7 build (SB/SLI).

Just a note: if (on XP) you right clicked the process in the task manager, chose Set affinity and enabled both cores for the ryzom's process, it would probably go up above 50%.

Nope....never breaks 50% ..... 1 core or 2

[...]I'd wonder if I needed to drill through the Avast firewall, but that wouldn't explain the fact that it happened while I was still using McAffee and that the change happened while using McAffee.

I will continue thinking on this matter.

3 more thoughts from me:

A major issue i had with another firewall was that it did DNS lookups for every connection. That particular firewall tried DNS lookups on every UDP packet (Ryzom uses a lot of UDP communication which doesn't use connections the same way TCP does). They stacked up until response times went ugly. You could try disabling DNS lookup for the firewall. They are for readability purposes (log, messages) only and not required for security.

Another thought: Maybe Microsoft Update auto-installed some windows defender stuff? That one should be disabled if there is another antivirus solution in place.

Third: You said your antivirus takes about 50% cpu (at least i remember you said...?) Find out what exactly does it do using that much cpu time.

The comment about my AV was back when I was using McAfee (and is why I am no longer using McAfee). Avast is much better behaved. I'll check the behavior of the firewall with respect to DNS, and I'll check out the windows defender settings, too. Thanks.

Found Windows Firewall ICS running. Have disabled, because Avast looks to be happy all by its lonesome. Will report back.

Unfortunately, that did not solve the problem. I looked into Avast and was not able to find anything I could understand about UDP and the firewall. Does anyone have experience with that?

I just want to bump on this thread, I am using Mavericks and Snow both have high cpu usage from 120% to 190%. Hope someone could direct me on what to do about this issue.

Hi Afriel -- No idea what Mavericks and Snow are, but how can CPU usage be greater than 100%?

Finally solved my problem by getting a new machine (forced by a crack on the MB -- which might have been related to the problem). Once I figured out the whole dual CPU setup on the new comp things have been fine.

1 thread is 100%. if you have multi core/thread cpu like intel 4 cores/8 threads for example, and process is using all 8 threads in full, then cpu usage in that case can be 800%.

Maverick and Snow(Leopard) are Mac OS X versions
