CPU usage 100%

[JeanClaudeTergal]

Hi!

I'm a new member of the community.

I've experienced 0ad recently.

I've not started to play yet but I've already a question.

I'm using kubuntu (precise pangolin) and the version of 0ad who stands in the official repository (I don't know the version number...)

The cpu usage is 100%.

The game seems run correctly.

Is this cpu usage regular?

Is it possible to limit the framerate?

Thank you!

Yes, it is to be expected. Please see the first item here: http://www.wildfiregames.com/forum/index.php?showtopic=15796

Hi Claude,

Try playing maps without water against maximum 1 AI player for the moment. Playing the game in multiplayer works even better!

We are aware of the high CPU usage, an overhaul of the pathfinder ought to improve matters.

for me it sounds like you 2 have misunderstood him…

I think he wanted the answer for this question: "Is it normal that the game consumes every cpu cycle it can grab, even if nothing happens like in the match setup screen?"

Am I right?

look at the screenshot(in the spoiler): even in the menu the game uses 100% of 2 cores(i’ve disabled dividing cpu load through number of cores to show it better)

that behavior causes my notebook to overheat even when i let the game idle in the menu

it looks like the game does some busy waiting or polling, which is quite bad

This is expected behaviour. It could probably be changed to not do this, however during game play it is likely to need a lot of cpu power anyway so I don't know whether it is worth spending time on this, I can't see many reasons for a player to sit in the menu unless waiting for a multiplayer game to start. Having a laptop which overheats under load is a hardware problem.
