Irrlicht Performance on Linux: Lag/Skipping?

thoughtcube · Post by **thoughtcube** » Sat May 24, 2008 11:50 am

Hello,

I am evaluating Irrlicht for a project of ours (it's on our shortlist of 3D engines). However, I seem to have a problem when running Irrlicht on my Linux machine, and I'd appreciate an answer if this is a problem with my setup or not.

Basically, all the samples run and give nice graphics, but rendering isn't smooth. Every few seconds there is a 'skip' where Irrlicht doesn't render all the frames. Like a visual stutter or lag. This happens on all the examples, and not just in the more graphics-intensive ones in particular, so it's odd. I tried to do a search on these forums for similar problems, but maybe I can't think of the right phrase.

I'm running on Ubuntu 8.04, on an Athlon3000 and Nvidia FX5200, and the Irrlicht samples run in fairly small windows, so I doubt it's an issue of my system not being strong enough.

Any ideas why I'm getting this problem? I hope its fixable so that we can continue to consider using Irrlicht, because this is a show-stopper at the moment. Thanks in advance.

You could try disabling compiz? That caused similar issues for me.

Could also be a driver problem, or a multi-core scheduling issue.

when you run it do you chose to render it in opengl or software mode?
Also have you installed your nvidia drivers?if not clicks system-administration-restricted drivers and check the box from there ubuntu should download your needed drivers.
