Awfully slow, full CPU usage

[anton.pussep]

I just compiled and installed the latest stable SVN version on my Debian 4.0. The compilation worked without any problems and I have nice .deb files now, many thanks for the great work! However, when I start the game it is awfully slow. It is hardly possible to move the mouse to a certain place in the main menu, not even mentioning the actual game...

I found out that the CPU usage rises to 100%. I suspected OpenGL being a problem, but glxinfo says that direct rendering is activated and glxgears runs almost without using the CPU at all. My chipset is a Intel mobile 915. I tested Debian stable with kernel 2.6.21.5 and Debian testing with kernel 2.6.18.8 with the very same effect. I configured everything according to http://www.larsen-b.com/Article/231.html and as I said, glxinfo output seems quite reasonable.

Any ideas what might be wrong?

your intel chipset is the problem - see http://ufoai.ninex.info/wiki/index.php/Manual/System_Requirements

if you find a solution - please let us know

I am running ufo:ai on a IBM X41 with i810 video driver under debian. First I had the same problems. But by changing config.cfg I got rid of them. Change/add the following line to config.cfg:  set gl_ext_pointparameters "0".

[Mattn]

that's good news - can you please send the vendor string of your intel card? or even better the hole ufoconsole.log (via pastebin maybe)

[Mattn]

can you maybe try the latest revision in trunk? does that fix your intel card problems?

[sparktherookie]

Wohoo, confirmed!

ibykus's fix makes this stunning game (finally!) run flawlessly on my machine.

Here are the specs:

- I'm running Ubuntu 7.04 "Feisty Fawn"
- The UFO:AI version is mattn's beta installer release (rev 9457)
- The video chipset is a Intel 945GM

Got IBM T60.
Intel Mobile 945GM
Fedora Core 6

With 2.1 FPS is about 6
With latest SVN version FPS jumped to 93
Game works well now.
Great work!
