Recently (the last week or so) I have noticed that the Ryzom client is taking up 80%-100% of my available CPU -- to the significant detriment of performance of my machine in other tasks, or even just in Ryzom. Is anyone else having this problem.

XP Home, SP3, 2GB memory. Used to run without glitch.

I'm on an iMac with dual processors and running Ryzom takes 98-100% of both processors most of the time, and has done since I signed up (mid June this year).

Having said that, once in Ryzom I can start something else going in the background (download, stream video/audio etc.) without any noticable effect on Ryzom. I do get disconnections out of the game, but that happens when nothing else is going on.

It seems that Ryzom is taking all available processor capacity, but then releasing capacity when something else needs it.

CPU usage is lower for me, at least on Linux (tested with both a Core 2 and a more recent Core i7).

You can easily reduce usage with cpulimit and it actually runs fine on 80% CPU down-clocked at 800MHz or 30% CPU at 2.2GHz.

This behaviour can be easily corrected with some throttling (frame rates and UI event handling) or it always uses as much CPU as it can get.

Marla -- Say wha???

That sort of sounded like English, but comprehension eludes me. If you can explain more thoroughly how one throttles the client, how to use cpulimit and things like that so that a geek who is not a PC guru can understand it, I'd love to listen. Remember that I'm on Windoze XP SP3 and not on Lunux. (AMD Athalon 64 3200+, 2.0 GHz//Nvidia 9600GT with 512MB memory to add to the specs given in my original post.)

The main thing is that I believe this behavior started only a week or so ago for me. Do any of the devs have words on this?

Sorry Bittty, I'll try to be more explicit :)

Throttling was meant as a possible solution on the dev side (e.g., provide an option for capping frame rates at least), but the equivalently valid solution is to cap the amount of CPU that is allowed to the ryzom client. Throttling generally relies on microsleep to reduce resource consumption (baiscally wasting time, but not using resources to do so as would happen in busy waiting), and limiting CPU usage works in the same fashion, but relying on the OS scheduler to only allocate a lower number of time slices to a given process.

For Windows, alas, I have not used it for almost 15 years, so I cannot help. For Linux, you can use:
$ cpulimit -l <percentage_allowed> -p <process_id>

For example to limit cpu usage to 50% on a ryzom_client that has process ID, say 19788:
$ cpulimit -l 50 -p 19788

I believe similar tools exist for Windows, but you should google this for more precise info.

As far as I'm concerned, I use a script to launch the client, which maps the process to the appropriate core and limits CPU usage, so I have not "perceived" any change.

Ryzom has, to my knowledge. always taken 100% of CPU if allowed, but scales back if other activity is going on. The last patch was months ago so there has been no change to the client.

Perhaps some local thing has changed? New software installed that is running in the background or something similar?

Files too fragmented - a common problem with Windows. I use both Mac and Windows PCs and this has the ring of familiarity about it.

Seem that you have got to the bottom of it. : )

I noticed again that my Win XP system is having 100% CPU usage from Ryzom ...

At the point where the login splash page is waiting for the input of the password!!!

And it is doing 100% CPU usage at all times during the game except during logout. The problem is that this usage is interfering with things like entering text into chatboxes. I have recently done a re-install and I regularly defrag my disk. Neither of these has changed a thing. I first started noticing this after the last major patch, but only just now looked at the system monitor and saw what I saw.

When it's waiting for the loging password it uses CPU to such an extent that it slows down Firefox (a 2% user under normal circumstances).

Sywindt -- there is no "scaling back". Why should Ryzom use 100% of the CPU when it isn't *doing* anything? What is it doing with those CPU cycles?

File fragmentation does not produce CPU usage, but disk access usage. That, at least as far as I can tell, is not up.

Yesterday did drastic procedure of completely downloaded the installer and re-installing from that, then patching and bringing back my save folder. Still have problems with text entry speed into chat boxes and interference with Firefox.

:(

I'll give that a try and see what happends, Lwiz. On the other hand with a wireless mouse I'm not sure how to make it "hardware based". :))

Just checked in the Intellipoint control window and could not see a hardward/software change button. Looked to see if there were updatable drivers for the mouse (and keybd), but nada. :((
