Once again game eating 100% CPU - Linux

DuoMaxwell you hit the nail on the head when you said high priority where when a game takes high priority there is a point where more power just doesn't help it.

Graphically the home brew 3d engine behind Regnum is on par with the id Tech 3 engine. For those of you who have never had the displeasure of working on a 3d game (I been doing this since Glide was popular) the Tech 3 engine is what was used for Quake3.

Just for fun I loaded Regnum on my personal desktop today (it also doubles as our devel SQL/Apache/SAMBA file server. I ran it in a window at a low resolution 1280x960 @ 16

Have a look @ CPU's usage from Regnum and Top it's only 3% off.



So in response to the reply from (Froste) "A game (any game) will always take whatever is available, if a game is only taking 40% of the cpu, then something else is taking 60%, or you are interpreting the data incorrectly" That good sir is a uneducated statement as my screen shot proves. My CPU's were 37.2% idle. This was with Apache/SQL/Dovecot/Gimp/Amarok/X windows/Gaim/Azureus/SAMBA/Sendmail active and running.

I fear if I made a habit of interpreting data incorrectly I would find my persons quite unemployed. @ 37% CPU usage Regnum HAS to be using only one core out of the 4 (2 dual-core Opterons (4 cores, 270 Italy) since running a synthetic Apache benchmark via (Jmeter) this box is only under 40% load @ 25,000 request @ 5,000 clients per second.

Don't get me right I really like Regnum and buy premium content just to support the game. It's fun and the game does not look bad graphically but I think there is plenty of room for optimization, at least for the Linux client. Regnum is not a graphically intensive game and unless the Linux client was built with debugging it should not use as much CPU.

Yet the game is just out of beta so I can't complain and I look forward to new releases of the Linux client.

On the last note magnet said If you have a dual core, it will use only one of the cores. but niclam from NGD said The games uses all the CPU it can chew its teeth on

I have to say it looks like Regnum in fact does not support (SMP/dual core) and this explains why WoW uses so much less since it does support a multi core arch. It does not matter how many teeth Regnum sinks it's teeth into if it's only sinking it's teeth into one of the four available cores between 2 CPU'S.

I guess I should also note everything here runs CentOS minus the Netra's that are running Solaris.
